SAFETY SAFETY INFORMATION For your safety and the safety of others, pay special attention to these precautions. Operator Responsibility • TOHATSU outboard motor is designed to give safe and dependable service if operated according to instructions. Read and understand the Owner’s Manual before operating the outboard motor. Failure to do so could result in personal injury or equipment damage. 6 Shift to the neutral position and then shift to the reverse position at low engine speed. Do not shift to the reverse position suddenly at high engine speed. • Gasoline is harmful or fatal if swallowed. Keep the fuel tank out of reach of children. • Gasoline is extremely flammable and is explosive under certain conditions. Refuel in a well-ventilated area with the engine stopped. • Do not smoke or allow flames or sparks where the engine is refueled or where gasoline is stored. • Do not overfill the fuel tank. After refueling make sure that the fuel tank cap is closed properly and securely. • Be careful not to spill any fuel while refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled make sure that the area is dry before starting the engine. • Know how to stop the engine quickly in case of emergency. Understand the use of all controls. • Do not exceed the boat manufacturer’s power recommendation, and be sure that the outboard motor is properly mounted. • Never permit anyone to operate the outboard motor without proper instruction. • Before operating the outboard motor, familiarize yourself with all laws and regulations relating to boating and the use of outboard motors. • Do not attempt to modify the outboard motor. • Always wear a life-jacket when on board. SAFETY • Do not operate the outboard motor without the engine cover. Exposed moving parts can cause injury. • Do not remove any guards, labels, shields, covers or safety devices; they are installed for your safety. • Stop the engine immediately if anyone falls overboard. • Do not run the engine while the boat is near anyone in the water. • Attach the emergency stop switch lanyard securely to the operator. The engine and exhaust system become very hot during operation and remain hot for a while after stopping. Contact with hot engine components can cause burns and may ignite some materials. • Avoid touching a hot engine or exhaust system. • Allow the engine to cool before performing maintenance or transporting. Carbon Monoxide Poisoning Hazard Exhaust contains poisonous carbon monoxide, a colorless and odorless gas. Breathing exhaust can cause loss of consciousness and may lead to death. • If you run the engine in an area that is confined, or even partially enclosed, the air can become contaminated with a dangerous amount of exhaust gas. To keep exhaust gas from building up, provide adequate ventilation. 7 2. SAFETY LABEL LOCATIONS These labels are in the locations shown.

Contact your dealer for more information. TACHOMETER The tachometer shows the engine speed in revolutions per minute. NMEA INTERFACE COUPLER 28 5. INSTALLATION Transom Height Improperly installed outboard motor can result in the outboard motor dropped into the water, boat not able to cruise straight ahead, engine speed not increase, and much fuel consumption. Do not exceed the boat manufacturer’s power recommendation. Damage and injury may result. T We recommend that the outboard motor be installed by an authorized TOHATSU outboard motor dealer. Consult the authorized TOHATSU dealer in your area for the Y-OP (User Optional Parts)/equipments installation and operation. Applicable Boat Select the boat suitable for the engine power. Engine power: BFT115A: 84.6 kW (115 PS) BFT150A: 110.3 kW (150 PS) Power recommendation is indicated on most of the boats. Type: T (Outboard Motor Transom Height) <when transom angle is 12°> L: 508 mm (20.0 in) X: 635 mm (25.0 in) Select the outboard motor which is correct for the boat transom height of your boat. 29 INSTALLATION Location Installation Height IDLE PORT TRANSOM HEIGHT 150 mm (5.9 in) or more 0 – 25 mm (0 – 1 in) CENTER LINE Install the outboard motor at the stern, at the center line of the boat. 30 100 mm (4 in) BOAT TRANSOM HEIGHT ANTICAVITATION PLATE The anticavitation plate of the outboard motor should be 0 – 25 mm (0 – 1 in) below the bottom of the boat. The correct dimensions differ according to the type of boat and the configuration of the bottom of the boat. Follow the manufacture’s recommended installation height. WATER LEVEL FULLY TRIM/TILT DOWN • The water level must be at least 100 mm (4 in) above the anticavitation plate, otherwise the water pump may not receive sufficient cooling water, and the engine will overheat. • Adverse effect to the engine can occur if the installation position of the outboard motor is too low. Trim/tilt down the outboard motor with the boat fully loaded and stop the engine. Check that the idle port is 150 mm (5.9 in) or more above the water level. INSTALLATION Outboard Motor Installation BOLT (4) WASHER (4) NUT (8) Standard torque: 55 N·m (5.6 kgf·m, 41 lbf·ft) The standard torque is given just as a guideline. Torque of the nut can be different according to the material of the boat. Consult with an authorized TOHATSU outboard motor dealer. LIFTING EYES (3) WASHER (8) STERN BRACKET 1. Apply the silicone sealant (Three Bond 1216 or equivalent) to the outboard motor mounting holes. 2. Set the outboard motor on the boat and secure with the bolts, washers, and lock nuts. Install the outboard motor securely. Loosely mounted outboard motor can result in accidental loss of the outboard motor and damage and injury to the equipment and personnel. Before installing the outboard motor on the boat, hang the outboard motor with the hoist or equivalent devise by attaching the three lifting eyes to the outboard motor. Use the hoist which allowable load is 250 kg (551 lbs) or above. 31 INSTALLATION Outboard Motor Angle Inspection (Cruising) INCORRECT CAUSES BOAT TO ‘‘SQUAT’’ Install the outboard motor at the best trim angle for stable cruising and maximum power. Trim angle too large: Incorrect causes boat to ‘‘squat.’’ INCORRECT CAUSES BOAT TO ‘‘PLOW’’ Trim angle too small: Incorrect causes boat to ‘‘plow.’’ CORRECT GIVES MAXIMUM PERFORMANCE The trim angle differs according to the combination of the boat, outboard motor, and propeller, and the operating conditions. Adjust the outboard motor so that it is perpendicular to the water surface (i.e. axis of the propeller is parallel with the water surface). 32 INSTALLATION Battery Connections Use a battery which has CCA (COLD CRANKING AMPERES) 622A at – 18°C (0°F) and a reserve capacity 229 minutes (12V-64Ah/ 5HR or 80Ah/20HR) or more specifications. The battery is an optional part (i.e. part to be purchased separately from the outboard motor). Batteries produce explosive gases: If ignited, an explosion can cause serious injury or blindness. Provide adequate ventilation when charging. • CHEMICAL HAZARD: Battery electrolyte contains sulfuric acid. Contact with eyes or skin, even through clothing, may cause severe burns. Wear a faceshield and protective clothing. • Keep flames and sparks away, and do not smoke in the area. ANTIDOTE: If electrolyte gets into your eyes, flush thoroughly with warm water for at least 15 minutes and call a physician immediately. • POISON: Electrolyte is poison. ANTIDOTE: ─ External: Flush thoroughly with water. ─ Internal: Drink large quantities of water or milk. Follow with milk of magnesia or vegetable oil, and call a physician immediately. • KEEP OUT OF REACH OF CHILDREN. To protect the battery from mechanical damage and to prevent the battery from falling or tipping over, the battery must be: • Installed in the correct size corrosion-resistant battery box. • Properly secured in the boat. • Secured in a location free from direct sunlight and water spray. • Secured away from the fuel tank to avoid potential sparks near the fuel tank. 33 INSTALLATION (–) TERMINAL (+) TERMINAL RED BLACK Connect the battery cables: 1. Connect the cable with the red terminal cover to the positive (+) terminal of the battery. 2. Connect the cable with the black terminal cover to the negative (–) terminal of the battery. When more than one outboard motor is mounted on a boat, connect a battery to each respective outboard motors. 34 • Be sure to connect the (+) side battery cable first. When disconnecting the cables, disconnect the (–) side first then the (+) side. • Unless the cables are properly connected to the terminals, the starter motor may fail to operate normally. • Be careful to avoid connecting the battery in reverse polarity, as this will damage the battery-charging system in the outboard motor. • Do not disconnect the battery cables while the engine is running. Disconnecting the cables while the engine is running, will damage the outboard motor’s electrical system. • Do not place the fuel tank near the battery. • Battery cable extension: Extending the original battery cable will cause the battery voltage to drop due to the increased length of the cable and number of connections. This voltage drop may cause the buzzer to sound momentarily when engaging the starter motor and may prevent the outboard from starting. If the outboard starts and the buzzer sounds momentarily, there may be barely sufficient voltage reaching the engine. WARNING: Battery posts, terminals, and related accessories contain lead and lead compounds. Wash your hands after handling. INSTALLATION Remote Control Installation (optional equipment) Improperly installed steering system, remote control box, and remote control cable, or installing those of the different types could cause unpredictable accident. Consult an authorized TOHATSU outboard motor dealer for proper installation. The control box is available in three types as shown. Select the most suitable control box for your outboard motor considering the installation position, operationability, etc. of the control box. See an authorized TOHATSU outboard motor dealer for further information. TOP-MOUNT TYPE CONTROL BOX AND SWITCH PANEL SIDE-MOUNT TYPE CONTROL BOX (FOR SINGLE OUTBOARD MOTOR TYPE) PANEL-MOUNT TYPE CONTROL BOX AND SWITCH PANEL TOP-MOUNT TYPE CONTROL BOX AND SWITCH PANELS (FOR DUAL OUTBOARD MOTOR TYPE) 35 INSTALLATION <Remote Control Box Location> <Remote Control Cable Length> REMOTE CONTROL LEVER REMOTE CONTROL BOX Install the remote control box in the position where is easy to operate the remote control lever and switches. Be sure that there are no obstacles on the route of the control cable. The control box position of the R2 type and the R3 type should be determined in the same manner. 36 Do not bend the remote control cable as sharp as its route diameter is 300 mm (11.8 in) or less, or it affects the service life of the cable and the remote control lever operation. REMOTE CONTROL CABLE Measure the distance from the control box to the outboard motor along the cable routing. Recommended cable length is 300 – 450 mm (11.8 – 17.7 in) longer than the measured distance. Set the cable along the predetermined route and be sure that it is long enough to the route. Connect the cable to the engine and be sure it is not kinked, bent sharp, pulled taut, or interfered while steering. INSTALLATION Propeller Selection Select the adequate propeller so that the engine speed at full throttle is BFT115A: 4,500 min-1 (rpm) to 6,000 min-1 (rpm). BFT150A: 5,000 min-1 (rpm) to 6,000 min-1 (rpm) when the boat is loaded. Engine speed varies according to the propeller size and the boat condition. Use of the outboard motor outside the full throttle speed range will adversely affect the engine and cause serious problem. Use of the correct propeller assures powerful acceleration, top speed, excellency in terms of economy and cruising comfort, and it assures longer engine life as well. Consult with your authorized TOHATSU outboard motor dealer for proper propeller selection. Fuel Line Connection Connect the fuel line to the tank and the outboard motor. Follow the boat manufacturer’s instructions. Gasoline is extremely flammable, and gasoline vapor can explode, causing serious injury or death. • Be careful not to spill fuel. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting, storing or transporting the engine. • Do not smoke or allow flames or sparks where fuel is refueled or stored. 37 6. PRE-OPERATION CHECKS BFT115A/150A is 4-stroke, water cooled outboard motor which uses unleaded regular gasoline for fuel. It also requires the engine oil. Check the following before operating the outboard motor. Engine Cover Removal/Installation ENGINE COVER Perform the following pre-operation checks with the engine stopped. Before each use, look around and underneath the engine for signs of oil or gasoline leaks. ENGINE COVER LATCH • To remove, pull the engine cover latch and lift the engine cover straight up. • To install, place the engine cover on the outboard motor, and push down evenly. When reinstalling the covers, make sure not to jam the wire harnesses in between the covers and engine case. 38 Do not operate the outboard motor without the engine cover. Exposed moving parts can cause injury. PRE-OPERATION CHECKS Engine Oil • Engine oil is a major factor affecting engine performance and service life. Nondetergent and low quality oils are not recommended, because they have inadequate lubricating properties. • Running the engine with insufficient oil can cause serious engine damage. <Recommended oil> Use 4-stroke high detergent, premium quality motor oil certified to meet or exceed U.S. automobile manufacturer’s requirements for API Service category SG, SH or SJ. Motor oils classified SG, SH or SJ will show this designation on the container. SAE 10W-30 is recommended for general use. <Inspection and Refilling> UPPER LEVEL MARK LOWER LEVEL MARK AMBIENT TEMPERATURE OIL LEVEL DIPSTICK 1. Position the outboard motor vertically, and remove the engine cover. 2. Remove the oil level dipstick and wipe with a clean rag. 3. Reinsert the dipstick all the way in, then pull it out and read the level. If near or below the lower level mark, remove the oil filler cap and fill to the upper level mark with the recommended oil. Tighten the oil filler cap and install the dipstick securely. Do not overtighten. 39 PRE-OPERATION CHECKS OIL FILLER CAP When the engine oil is contaminated or discolored, replace with the fresh engine oil (see page 85 for replacement interval and procedure). 4. Install the engine cover and lock it securely. Do not overfill the engine oil. Check the engine oil after refilling. Excessive engine oil as well as the insufficient oil could cause damage to the engine. 40 PRE-OPERATION CHECKS When you check the oil level with the dipstick, you might notice the engine oil appears milky or the oil level has increased. If you notice either condition, change the engine oil. See the following table for an explanation of these conditions. Operating Method Running the engine below 3,000 rpm for more than 30% of the time so the engine does not warm up. Frequent starting and stopping without allowing the engine to warm up. Result Effect • Water condenses in the engine and mixes with the oil, resulting in a milky appearance. • Unburned fuel mixes with the oil, increasing the volume of oil. The engine oil deteriorates, becomes less efficient as a lubricant, and causes an engine malfunction. Fuel Check the fuel level and refill if necessary. Do not fill the fuel tank above the UPPER LIMIT. Refer to the boat manufacturer’s instructions. Use unleaded gasoline with a Research Octane Number of 91 or higher (a Pump Octane Number of 86 or higher). Use of leaded gasoline may cause damage to the engine. Never use an oil/gasoline mixture or dirty gasoline. Avoid getting dirt, dust or water in the fuel tank. 41 PRE-OPERATION CHECKS Gasoline is extremely flammable and is explosive under certain conditions. • Refuel in a well-ventilated area with the engine stopped. • Do not smoke or allow flames or sparks in the area where the engine is refueled or where gasoline is stored. • Do not overfill the fuel tank (there should be no fuel in the filler neck). After refueling, make sure the fuel filler cap is closed properly and securely. • Be careful not to spill fuel when refueling. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine. • Avoid repeated or prolonged contact with skin or breathing of vapor. KEEP OUT OF REACH OF CHILDREN. 42 GASOLINE CONTAINING ALCOHOL If you decide to use a gasoline containing alcohol (gasohol), be sure its octane rating is at least as high as that recommended by TOHATSU. There are two types of “gasohol”: one containing ethanol, and the other containing methanol. Do not use gasohol that contains more than 10% ethanol. Do not use gasoline containing more than 5% methanol (methyl or wood alcohol) and that does not also contain co-solvents and corrosion inhibitors for methanol. • Fuel system damage or engine performance problems resulting from the use of gasoline that contains more alcohol than recommended is not covered under the warranty. • Before buying gasoline from an unfamiliar station, first determine if the gasoline contains alcohol, if it does, find out the type and percentage of alcohol used. If you notice any undesirable operating symptoms while using a particular gasoline. Switch to a gasoline that you know contains less than the recommended amount of alcohol. PRE-OPERATION CHECKS Propeller and Cotter Pin Inspection COTTER PIN The propeller blades are thin and sharp. Careless handling of the propeller can result in injury. When checking the propeller: • Remove the emergency stop switch clip to prevent an accidental start of the engine. • Wear heavy gloves. Propeller rotates rapidly while cruising. Before starting the engine, check the propeller blades for damage and deformation and replace if necessary. Obtain a spare propeller for the event of an unpredictable accident while cruising. If no spare propeller is available, return to the pier at low speed and replace (see page 104). Consult an authorized TOHATSU outboard motor dealer for propeller selection. Keep the spare washer, castle nut and cotter pin with you on your boat. CASTLE NUT PROPELLER Engine speed varies according to the propeller size and the boat condition. Use of the outboard motor outside the full throttle speed range will adversely affect the engine and cause a serious problem. Use of the correct propeller assures powerful acceleration, top speed, excellency in terms of economy and cruising comfort, and it assures longer engine life as well. Consult with your authorized TOHATSU outboard motor dealer for proper propeller selection. 1. Check the propeller for damage, wear, or deformation. Replace whenever the propeller is faulty (see page 104). 2. Check whether the propeller is installed properly. 3. Check the cotter pin for damage. 43 PRE-OPERATION CHECKS Water Separator (R2 type) Remote Control Lever Friction (R1 type) INTAKE MANIFOLD To increase friction CONTROL LEVER FRICTION ADJUSTER To increase friction To decrease friction To decrease friction CONTROL LEVER FRICTION ADJUSTER (R3 type) Check whether the remote control lever moves smoothly. Friction of the remote control lever can be adjusted by turning the control lever friction adjuster right or left. To increase friction To decrease friction CONTROL LEVER FRICTION ADJUSTER 44 WATER SEPARATOR Water separator is located below the intake manifold. Check the water separator for water accumulation. Clean it or consult with an authorized TOHATSU outboard motor dealer for cleaning (see page 97). PRE-OPERATION CHECKS Battery Battery handling differs according to the type of the battery and the instructions described below might not be applicable to the battery of your outboard. Refer to the battery manufacturer’s instructions. Battery Inspection Check whether the battery fluid is between the upper and lower levels, and check the vent hole in the battery caps for clogging. If the battery fluid is near or below the lower level, add the distilled water to the upper level (see page 100). Check that the battery cables are connected securely. If the battery terminals are contaminated or corroded, remove the battery and clean the terminals (see page 101). POSITIVE (+) TERMINAL UPPER LEVEL LOWER LEVEL Batteries produce explosive gases: If ignited, an explosion can cause serious injury or blindness. Provide adequate ventilation when charging. • CHEMICAL HAZARD: Battery electrolyte contains sulfuric acid. Contact with eyes or skin, even through clothing, may cause severe burns. Wear a faceshield and protective clothing. • Keep flames and sparks away, and do not smoke in the area. ANTIDOTE: If electrolyte gets into your eyes, flush thoroughly with warm water for at least 15 minutes and call a physician immediately. • POISON: Electrolyte is poison. ANTIDOTE: ─ External: Flush thoroughly with water. ─ Internal: Drink large quantities of water or milk. Follow with milk of magnesia or vegetable oil, and call a physician immediately. • KEEP OUT OF REACH OF CHILDREN. 45 PRE-OPERATION CHECKS Other Checks (2) (5) TOOL KIT (page 82) (4) (3) (1) Check the following items: (1) The fuel hose for kinking, collapsing or a loose connection. (2) The remote control lever for smooth operation. (3) The switches for correct operation. (4) The stern bracket for damage. (5) The tool kit for missing spare parts and tools (page 82). (6) The anode metal for damage, looseness or excessive corrosion. 46 (6) The anode (sacrificed metal) helps to protect the outboard motor from corrosion damage; it must be exposed directly to the water whenever the outboard motor is in use. Replace the anodes when they have been reduced to about two-thirds of their original size, or if they are crumbling. The possibility of corrosion damage is increased if the anode is painted over or allowed to deteriorate. Parts/materials which should be installed on board: • Owner’s Manual • Tool kit • Spare parts: spark plugs, engine oil, spare propeller, castle nut, washer and cotter pin. • Spare emergency stop switch clip. • Other parts/materials required by laws/regulations. 7. STARTING THE ENGINE Fuel Priming Do not touch the priming bulb with the engine running or when tilting up the outboard motor. The vapor separator could overflow. ARROW OUTLET END (outboard motor side) PRIMING BULB INLET END (tank side) Hold the priming bulb so that the outlet end is higher than the inlet (so that the arrow on the priming bulb points up), and squeeze it until it feels firm, indicating that fuel has reached the outboard motor. Check for leaks. Starting the Engine (R1 type) The exhaust contains poisonous carbon monoxide. Do not start the engine in a poor ventilation area such as in a boat house. To prevent damage to the outboard from overheating, never run the engine with the propeller out of water. EMERGENCY STOP SWITCH STOP Be careful not to spill any fuel. Spilled fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before starting the engine. EMERGENCY STOP EMERGENCY STOP SWITCH CLIP SWITCH LANYARD 47 STARTING THE ENGINE 1. Insert the emergency stop switch clip at one end of the emergency stop switch lanyard into the emergency stop switch. Attach the other end of the emergency stop switch lanyard securely to the operator. SPARE EMERGENCY STOP SWITCH CLIP NEUTRAL NEUTRAL If the operator does not attach the emergency stop switch lanyard, and is thrown from his seat or out of the boat, the out-of-control boat can seriously injure the operator, passengers, or bystanders. Always properly attach the lanyard before starting the engine. The engine will not start unless the emergency stop switch clip is engaged with the emergency stop switch. 48 REMOTE CONTROL LEVER A spare emergency stop switch clip is provided on the remote control box. 2.

If the engine does not start within 5 seconds, wait at least 10 seconds before running the starter motor again. • Do not turn the engine switch key to the START position while the engine is running. COOLING WATER CHECK HOLE ENGINE SWITCH KEY 4. Turn the engine switch key to the START position and hold it there until the engine starts. When the engine starts, release the key, allowing it to return to the ON position. The ‘‘Neutral Starting System’’ prevents the engine from being started unless the control lever is set in the N (neutral) position even though the engine is cranked by the starting engine. COOLING WATER INTAKE PORT (each side) 5. After starting, check whether the cooling water is flowing out of the cooling water check hole. Amount of water flowing out of the check hole might vary due to the thermostat operation, but this is normal. 49 STARTING THE ENGINE If water does not flow out, or if steam comes out, stop the engine. Check to see if the screen in the cooling water intake port is obstructed and remove foreign materials if necessary. Check the cooling water check hole for clogging. If water still does not flow out, have your outboard motor checked by an authorized TOHATSU outboard motor dealer. Do not operate the engine until the problem has been corrected. 6. Check to see if the oil pressure indicator turns ON. If it does not turn on, stop the engine and perform the following inspections. 1) Check the oil level (see page 39). 2) If the oil level is normal and the oil pressure indicator light does not turn ON, consult with an authorized TOHATSU outboard motor dealer. 50 OIL PRESSURE INDICATOR LIGHT NORMAL: ON ABNORMAL: OFF 7.

Cruising at high speed without warming the engine up may cause engine damage. Before leaving the dock, check the operation of the emergency stop switch. 8. OPERATION Break-in Procedure Break-in period: 10 hours Break-in operation allows the mating surfaces of the moving parts to wear evenly and thus ensures proper performance and longer outboard motor life. Break-in your new outboard motor as follows. First 15 minutes: Run the outboard motor at trolling speed. Use the minimum amount of throttle opening necessary to operate the boat at a safe trolling speed. Next 45 minutes: Run the outboard motor up to a maximum of 2,000 to 3,000 min-1 (rpm) or 10% to 30% throttle opening. Next 60 minutes: Run the outboard motor up to maximum of 4,000 to 5,000 min-1 (rpm) or 50% to 80% throttle opening. Short bursts of full throttle are acceptable but do not operate the outboard motor continuously at full throttle. Next 8 hours: Avoid continuous full throttle operation (100% throttle opening). Do not run the outboard motor at full throttle for more than 5 minutes at a time. For boats that plane easily, bring the boat up on plane then reduce the throttle opening to the specified break-in settings called out above. 55 OPERATION Gear Shifting (R1 type) REMOTE CONTROL LEVER NEUTRAL FORWARD FORWARD NEUTRAL REVERSE NEUTRAL REVERSE MAXIMUM OPENING Moving the remote control lever further from approximately 30° will increase throttle opening and boat speed.

Move the remote control lever from NEUTRAL toward FORWARD position. R1 type: Moving about 30° engages the gear. Moving the remote control lever further opens the throttle and increases the engine speed. R2, R3 types: Moving about 35° engages the gear. Moving the remote control lever further opens the throttle and increases the engine speed. For the sake of fuel economy, open the throttle about 80%. • When cruising at full throttle, note that the engine speed must be in the range BFT115A: between 4,500 min-1 (rpm) and 6,000 min-1 (rpm), BFT150A: between 5,000 min-1 (rpm) and 6,000 min-1 (rpm). • If you feel that the engine speed jumped up when the hull jumped or at ventilation, cruise the boat by returning the throttle to the slow speed side. • See “Propeller Selection” (page 37) for a relation between the propeller and the engine speed. Do not operate without the engine cover. Exposed moving parts could cause injury; water may damage the engine. For best performance, passengers and equipment should be distributed evenly to balance the boat. 60 OPERATION TRL (Trolling) Control Switch (optional equipment) TROLLING CONTROL SWITCH PANEL UP DOWN TRL (Trolling) CONTROL SWITCH UP: Increase engine speed DN: Reduce engine speed After the engine has warmed up, keeping the UP or DN button pushed when cruising with the throttle fully closed, changes the mode to trolling mode. A long buzz sounds once. When the mode is changed to trolling mode, the engine speed is 650 min-1 (rpm). Continuing to press the switch will not decrease or increase the engine speed beyond the lower (650 min-1 (rpm)) or higher (900 min-1 (rpm)) limit. If you try to do this, a short buzz sounds twice. The throttle may be operated while in trolling mode. The trolling mode is cancelled when you reach 3,000 min-1 (rpm). You can adjust the engine speed by 50 min-1 (rpm) every time you press the switch once. You will hear a short buzz. The engine speed can be adjusted within the range of 650 – 900 min-1 (rpm). 61 OPERATION Trimming the Outboard Motor POWER TRIM/TILT SWITCH (R1 type) Press UP to raise bow. Press UP to raise bow.

To trim down slightly, press on DN (down) in the same manner. OPERATION • Improper trim angle results in unstable steering condition. • Do not trim excessively while cruising through rough waves, or it may cause an accident. • Excessive trim angle can result in cavitation and racing of the propeller, and trimming up the outboard motor excessively can cause damage to the water pump. • Decrease the trim angle on high speed turns to reduce the possibility of propeller ventilation. • Improper outboard motor trim angle can result in an unstable steering condition. OUTBOARD MOTOR TRIMMED TOO LOW OUTBOARD MOTOR TRIMMED TOO HIGH OUTBOARD MOTOR TRIMMED CORRECTLY When cruising: (A) Into a high wind, trim the outboard motor down slightly to lower the bow and improve boat stability. (B) With a tail wind, trim the outboard motor up slightly to raise the bow and improve boat stability. (C) Through rough waves, do not trim the outboard motor too low or too high to avoid an unstable steering condition. 63 OPERATION Trim Meter (optional equipment) The trim meter indicates the trim angle of the outboard motor. Refer to the trim meter, and press the UP or DN (down) portion of the power trim/ tilt switch to adjust the outboard motor trim angle to achieve boat performance and stability. BOW TOO LOW DUE TO 1. LOAD IN THE FRONT 2. OUTBOARD MOTOR TRIMMED TOO LOW BOW TOO HIGH DUE TO 1. LOAD IN THE REAR 2. OUTBOARD MOTOR TRIMMED TOO HIGH With the outboard motor trimmed low the trim meter will read as shown. To raise the bow increase the outboard motor trim angle by pressing the UP portion of the power trim/tilt switch. With the outboard motor trimmed high the trim meter will read as shown. To lower the bow decrease the outboard motor trim angle by pressing the DN (down) portion of the power trim/tilt switch. The illustration represents R1 type. Perform the same procedure for the other types. 64 OPERATION Tilting the Outboard Motor Tilt the outboard motor to prevent the propeller and gear case from hitting the bottom when the boat is beached or stopped in shallow water.

LOCK TRIM ROD STERN BRACKET Tilt up the outboard motor using the tilt lock lever when mooring the boat. Shift the remote control lever into the NEUTRAL position and stop the engine before tilting up the outboard motor. Before tilting up, leave the outboard motor in the running position for one minute after stopping the engine to drain the water from inside the engine. 66 Stop the engine and disconnect the fuel line from the outboard motor before tilting the outboard motor. 1. Raise the outboard motor as full as it goes using the power trim/tilt switch. 2. Move the tilt lock lever to the LOCK position and lower the outboard motor until the lock lever contacts the stern bracket. 3. Press the DN (down) of the power trim/tilt switch and fully shorten the trim rods. OPERATION (R3 type) (DUAL TYPE) POWER TRIM/TILT SWITCH (RIGHT) (LEFT) When the boat is mounted with the two outboard motors, tilt up the right and left outboard motors one by one using the switch. Set the tilt lock lever of one outboard motor at the LOCK position, then tilt up another outboard motor. After tilting down the outboard motors, adjust the trim angle of the right and left outboard motors using the switch. Power Tilt Switch (outboard motor pan) POWER TILT SWITCH When you are away from the power trim/tilt switch on the control lever side, you can operate the power tilt switch on the outboard motor side. The switch operation is the same as that of the power trim/tilt switch on the remote control lever side. Do not operate this power tilt switch on the outboard motor while sailing. 67 OPERATION Manual Relief Valve MANUAL RELIEF VALVE POWER (To fix) MANUAL (To release) When power trim/tilt system does not operate because of dead battery or faulty power trim/tilt motor, the outboard motor can be manually tilted up or down by operating the manual relief valve. To tilt the outboard motor manually, turn the manual relief valve under the stern bracket 1 or 2 turns counterclockwise using a screwdriver. 68 After tilting up/down manually, close the manual relief valve to lock the outboard motor in the position. Check that no person is under the outboard motor before carrying out this operation because if the manual relief valve is loosened (turned counterclockwise) when the outboard motor is tilted up, the outboard motor will suddenly tilt down. The manual relief valve must be tightened securely before operating the outboard motor or the outboard motor could tilt when operating in reverse. OPERATION Trim Tab Adjustment TIGHTENING BOLT RIGHT LEFT RIGHT LEFT TRIM TAB The trim tab is provided to adjust for “torque steer” which is a reaction of the propeller rotation or propeller torque. If during a high speed turn an unequal amount of effort is required to turn the boat right or left, adjust the trim tab so that an equal amount of effort is required. Distribute the load evenly in the boat and run the boat in a straight course at full throttle. Slightly turn the steering wheel for both right and left turns to determine the amount of effort required. If less effort is required to make left turns: Loosen the trim tab tightening bolt and turn the rear end of the trim tab toward the left. Tighten the bolt securely. If less effort is required to make right turns: Loosen the trim tab tightening bolt and turn the rear end of the trim tab toward the right. Tighten the bolt securely. Make small adjustments at a time and retest. Incorrect trim tab adjustment can cause adverse steering. 69 OPERATION Engine Protection System <Engine Oil Pressure, Overheat, Water Contamination, PGM-FI and ACG Warning Systems> OIL PRESSURE INDICATOR (GREEN) OIL PRESSURE INDICATOR (GREEN) ACG INDICATOR (RED) ACG INDICATOR (RED) Each warning system of PGM-FI, ACG, oil pressure, overheat, and water contamination is activated as described in the following table. BUZZER OVERHEAT INDICATOR (RED) PGM-FI INDICATOR BUZZER (RED) (R1 type) If the engine oil pressure drops and/ or the engine overheats, either or both warning systems could be activated. When activated the engine speed will decrease gradually and the oil pressure indicator will turn OFF and the overheat indicator will turn ON. A continuous buzzer will sound on 70 If the engine overheats, the engine will stop in 20 seconds after the engine protection system will limit engine speed. OVERHEAT INDICATOR (RED) PGM-FI INDICATOR (RED) (R2, R3 types) the remote control type. The engine speed can not be increased with a larger throttle opening until the malfunction is corrected. When the malfunction is corrected the engine speed will increase gradually. OPERATION System INDICATOR LIGHTS Overheat ACG (Red) (Red) PGM-FI (Red) BUZZER CORRESPONDING SYSTEM With the engine switch key turned on: ON (2 times) Symptom Oil pressure (Green) At starting ON (2 sec) ON (2 sec) ON ON (2 sec) During operation ON OFF OFF OFF OFF Low oil pressure OFF OFF OFF OFF ON (continuously) Overheat ON ON OFF OFF ON (continuously) ACG warning ON OFF ON OFF PGM-FI warning ON* OFF* OFF ON Water contamination ON OFF OFF OFF alternating ON and OFF (at long intervals) alternating ON and OFF (at long intervals) alternating ON and OFF (at short intervals) Some indicator and/or buzzer will be activated at the same time due to the occurrence of a malfunction. *: Occasionally may blink due to the occurrence of a malfunction. 71 OPERATION When the oil pressure warning system is activated: COOLING WATER CHECK HOLE 1. Stop the engine immediately and check the engine oil level (see page 39). 2. If the oil is up to the recommended level, restart the engine. If the oil pressure warning system stops after 30 seconds, the system is normal. If the throttle was closed suddenly after cruising at full throttle, the engine speed may drop below the specified idle speed. This could cause the oil pressure warning system to activate momentarily. 3. If the oil pressure warning system stays activated after 30 seconds, return to the closest boat landing and contact your closest authorized TOHATSU outboard motor dealer. 72 When the overheat warning system is activated: 1. Return the remote control lever to the N (neutral) position immediately. Check to see if water is flowing out of the cooling water check hole. 2. If water is flowing out of the cooling water check hole, continue idling for 30 seconds. If the overheat warning system stops after 30 seconds the system is normal. If the engine is turned off after running at full throttle, the engine temperature may rise above normal. If the engine is restarted, shortly after being turned off, the overheat warning system could be activated momentarily. OPERATION When the PGM-FI activated: 1. Consult with an authorized TOHATSU outboard motor dealer. When the ACG warning system is activated. 1. Check the battery (see page 45). If the battery is OK, consult with an authorized TOHATSU outboard motor dealer. COOLING WATER INTAKE PORT (each side) 3. If the overheat warning system stays activated, stop the engine. Tilt up the outboard motor and check the water intakes for obstructions. If there are no obstructions at the water intakes, return to the closest boat landing and contact your closest authorized TOHATSU outboard motor dealer. WATER SEPARATOR When the water separator buzzer sounds: 1. Check the water separator for water contamination. If water is accumulated, clean them (see page 97). 73 OPERATION <Over-rev Limiter> This outboard motor is equipped with an engine over-rev limiter which activates when the engine speed increases excessively. The over-rev limiter can be activated while cruising, tilting up the outboard motor, or when ventilation occurs during a sharp turn. When the over-rev limiter is activated: 1. Reduce the throttle opening immediately and check the trim angle. 2. If the trim angle is correct but the over-rev limiter stays activated, stop the engine, check the condition of the outboard motor, check to see if the correct propeller is installed and check it for damage. Correct or service as necessary, by contacting your authorized TOHATSU outboard motor dealer. 74 Shallow Water Operation <Anodes> Excessive trim/tilt angle during operation can cause the propeller to raise out of the water and cause propeller ventilation and engine over-revving. Excessive trim/tilt angle can also damage the water pump and overheat the engine. ANODE (each side of extension case) ANODE (stern bracket) The anodes are a sacrificial material which helps to protect the outboard motor from corrosion. Painting or coating the anodes will lead to rust and corrosion damage to the outboard motor. There are also 2 small sacrificial anodes in the water passages of the engine block. When operating in shallow water, tilt the outboard motor up to prevent the propeller and gear case from hitting the bottom (see page 65). With the outboard motor tilted up, operate the outboard motor at low speed. Monitor the cooling water check hole for water discharge. Be sure that the outboard motor is not tilted so high that the water intakes are out of the water. OPERATION Multiple Outboard Motors On boats equipped with more than one outboard motor, all motors normally operate at the same time. If one or more motor(s) is stopped while the other(s) is running, put the stopped motor in “N” (neutral) and tilt it up so its propeller is above the water’s surface. If the propeller of the stopped motor is left in the water, it may turn as the boat moves through the water, causing a reverse flow of water from the exhaust side. This reverse flow will happen if the stopped engine’s propeller is in the water, its gearshift is in “R” (reverse), and the boat is moving forward. Reverse flow can cause an engine malfunction. 75 9. STOPPING THE ENGINE Emergency Engine Stop Normal Engine Stop (R1 type) NEUTRAL EMERGENCY STOP SWITCH LANYARD NEUTRAL STOP NEUTRAL STOP EMERGENCY STOP SWITCH CLIP EMERGENCY STOP SWITCH LANYARD (R2, R3 types) Pull the lanyard of the emergency stop switch and remove the emergency stop switch clip from the switch; this will stop the engine. It is a good idea to stop the engine with the emergency stop switch lanyard from time to time to be sure that the emergency stop switch is operating properly. 76 REMOTE CONTROL LEVER REMOTE CONTROL LEVER NEUTRAL (R2 type) NEUTRAL (R1 type) 1. Move the remote control lever(s) to the NEUTRAL position. After sailing with the throttle fully REMOTE open, cool down the engine by CONTROL LEVER running it at the idle speed for a few minutes.

TRANSPORTING Fuel Line Disconnection Before transporting the outboard motor, disconnect and remove the fuel line. Gasoline is extremely flammable, and gasoline vapor can explode, causing serious injury or death. • Be careful not to spill fuel. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before storing or transporting the outboard motor. • Do not smoke or allow flames or sparks where fuel is drained or stored. 78 Transporting LIFTING EYES When transporting the outboard motor on a vehicle, perform the following. 1. Remove the engine cover (see page 38). HOIST HOOKS 2. Set the hoist hooks against the lifting eyes and hang the outboard motor to remove it from the boat. TRANSPORTING Trailering When trailering or transporting the boat with the outboard motor attached, it is recommended that the outboard motor remain in normal running position. OUTBOARD MOTOR STAND 3. Secure the outboard motor on an outboard motor stand with the mounting bolts and nuts. Do not trailer or transport the boat with the outboard motor in the tilted position. The boat or outboard motor could be severely damaged if the outboard motor drops. The outboard motor should be trailered in the normal running position. If there is insufficient road clearance in this position, then trailer the outboard motor in the tilted position using an outboard motor support device such as a transom saver bar, or remove the outboard motor from the boat. 4. Remove the hoist hook and reinstall the engine cover. 79 11. CLEANING AND FLUSHING After each use in salt water or dirty water, thoroughly clean and flush the outboard motor with fresh water. Do not apply water or corrosion inhibitor directly to the electrical components under the engine cover, such as the AC generator, LAF sensor, or the AC generator belt. If water or corrosion inhibitor penetrates these components, they may be damaged. Before applying a corrosion inhibitor, cover the AC generator, belt and LAF sensor with a protective material to prevent damage. Shut off the engine before performing the cleaning and flushing. 1. Disconnect the fuel line from the outboard motor. 2. Tilt down the outboard motor. 80 FLUSH PLUG CONNECTOR FLUSH PLUG CONNECTOR WATER HOSE WATER HOSE JOINT (commercially available) 3. Clean and wash the outside of the outboard motor with fresh water. 6. Connect a fresh water hose to the water hose joint. 4. Remove the flush plug connector from the outboard motor. 7.

MAINTENANCE Submerged Outboard Motor A submerged outboard motor must be serviced immediately after it is recovered from the water in order to minimize corrosion. If there is a TOHATSU outboard motor dealer nearby, take the outboard motor immediately to the dealer. If you are far from a dealer, proceed as follows: 1. Remove the engine cover, and rinse the outboard motor with fresh water to remove salt water, sand, mud, etc. 3. Change the engine oil (see page 85). If there was water in the engine crankcase, or if the used engine oil showed signs of water contamination, then a second engine oil change should be performed after running the engine for 1/2 hour. 4. Remove the spark plugs (see page 87). Operate the starter to expel water from the engine’s cylinder. 5. Pour a teaspoon of engine oil into each spark plug hole to lubricate the inside of the cylinders. Reinstall the spark plugs. If the outboard motor was running when it submerged, there may be mechanical damage, such as bent connecting rods. If the engine binds when cranked, do not attempt to run the outboard motor until it has been repaired. 2. Drain the vapor separator as described on page 107. 105 MAINTENANCE 6. Install the engine cover and lock the latch securely (see page 38). 7. Attempt to start the engine. • If the engine fails to start, remove the spark plugs, clean and dry the electrodes, then reinstall the spark plugs and attempt to start the engine again. • If there was water in the engine crankcase, or the used engine oil showed signs of water contamination, then a second engine oil change should be performed after running the engine for 1/2 hour. • If the engine starts, and no mechanical damage is evident, continue to run the engine for 1/2 hour or longer (be sure the water level is at least 100 mm (4 in) above the anticavitation plate). 106 8. As soon as possible, take the outboard motor to a TOHATSU outboard motor dealer for inspection and service. 13. STORAGE For longer service life of the outboard motor, have your outboard motor serviced by an authorized TOHATSU outboard motor dealer before storage. However, the following procedures can be performed by you, the owner, with a minimum of tools. Fuel Gasoline spoils very quickly depending on factors such as light exposure, temperature and time. In worst cases, gasoline can be contaminated within 30 days. Using contaminated gasoline can seriously damage the engine (fuel system clogged, valve stuck). Such damage due to spoiled fuel is disallowed from coverage by the warranty. To avoid this please strictly follow these recommendations: • Only use specified gasoline (see page 41). • Use fresh and clean gasoline. • To slow deterioration, keep gasoline in a certified fuel container. • If long storage (more than 30 days) is foreseen, drain fuel tank and vapor separator. Vapor Separator Draining Gasoline is extremely flammable, and gasoline vapor can explode, causing serious injury or death. Do not smoke or allow flames or sparks in your working area. KEEP OUT OF REACH OF CHILDREN. • Be careful not to spill fuel. Spilled fuel or fuel vapor may ignite. If any fuel is spilled, make sure the area is dry before storing or transporting the outboard motor. • Do not smoke or allow flames or sparks where fuel is drained or stored. 107 STORAGE FRONT BRACKET CLAMP 5. Tilt up the outboard motor. 6. When the gasoline starts to flow out of the drain tube, tilt up the outboard motor and hold it in the position until the gasoline stops flowing. After draining the gasoline completely, return the outboard motor to the vertical position. DRAIN SCREW DRAIN TUBE 7. After draining thoroughly, tighten the drain screw securely. VAPOR SEPARATOR 1. Remove the engine cover. 2. Unhook the drain tube from the front bracket clamp. 3. Set the end of the tube toward the outside of the engine undercase. Draining the fuel becomes easier when the front end of the drain tube is as low as possible. 4. Loosen the vapor separator drain screw. 108 8. Clamp the drain tube on the front bracket clamp. Engine Oil 1. Change the engine oil (see page 85). 2. Remove the spark plugs (see page 87), and remove the clip from the emergency stop switch. 3. Pour 1 – 2 teaspoons (5 – 10 cm3) of clean engine oil into the cylinder. 4. Rotate the engine a few revolutions to distribute the oil in the cylinders. 5. Reinstall the spark plugs (see page 90). STORAGE Battery Storage Battery handling differs according to the type of the battery and the instructions described below might not be applicable to the battery of your outboard motor. Refer to the battery manufacturer’s instructions. Batteries produce explosive gases: If ignited, an explosion can cause serious injury or blindness. Provide adequate ventilation when charging. • CHEMICAL HAZARD: Battery electrolyte contains sulfuric acid. Contact with eyes or skin, even through clothing, may cause severe burns. Wear a faceshield and protective clothing. • Keep flames and sparks away, and do not smoke in the area. ANTIDOTE: If electrolyte gets into your eyes, flush thoroughly with warm water for at least 15 minutes and call a physician immediately. • POISON: Electrolyte is poison. ANTIDOTE ─ External: Flush thoroughly with water. ─ Internal: Drink large quantities of water or milk. Follow with milk of magnesia or vegetable oil, and call a physician immediately. • KEEP OUT OF REACH OF CHILDREN. (+) TERMINAL (–) TERMINAL RED BLACK 1. Disconnect the battery cable at the battery negative (–) terminal, then at the battery positive (+) terminal. 2. Remove the battery and clean the battery terminals and battery cable terminals with a wire brush or sand paper. Clean the battery with a solution of baking soda and warm water, taking care not to get the solution of water in the battery cells. Dry the battery thoroughly. 109 STORAGE UPPER LEVEL Outboard Motor Position (Port side turned down as shown.) LOWER LEVEL 3. Fill the battery with distilled water to the upper level line. Never overfill the battery. 4. Store the battery on a level surface in a cool, dry, well ventilated place out of direct sunlight. 5. Once a month, check the specific gravity of the electrolyte and recharge as required to prolong battery life. 110 OUTBOARD MOTOR STAND Transport and store the outboard motor either vertically or horizontally, as shown above. Attach the stern bracket to stand and secure the outboard motor with bolts and nuts. Store the outboard motor in a well-ventilated area free from direct sunlight and humidity. Vertical transport or storage: Attach the stern bracket to a stand. Horizontal transport or storage: Rest the outboard motor on a cushion of protective material. Do not place the outboard motor on its side during a prolonged period of storage. If you are obliged to place the outboard motor on its side, drain the engine oil, protect the outboard motor by wrapping it with the urethane material or the blanket as shown. 14. DISPOSAL To protect the environment, do not dispose of this product, battery, engine oil, etc. carelessly by leaving them in the waste.
