GENERAL INFORMATION
Boater's Responsibilities
The operator (driver) is responsible for the correct and safe operation of the boat and safety of its occupants and general public. It is strongly recommended that each operator (driver) read and understand this entire manual before operating the outboard.
Be sure at least one additional person onboard is instructed in the basics of starting and operating the outboard and boat handling in case the driver is unable to operate the boat.
Before Operating Your Outboard
Read this manual carefully. Learn how to operate your outboard properly. If you have any questions, contact your dealer.
Safety and operating information that is practiced, along with using good common sense, can help prevent personal injury and product damage.
This manual as well as safety labels posted on the outboard use the following safety alerts to draw your attention to special safety instructions that should be followed.
!
DANGER
Indicates a hazardous situation which, if not avoided, will result in death or serious injury.
!
WARNING
Indicates a hazardous situation which, if not avoided, could result in death or serious injury.

GENERAL INFORMATION
Boat Horsepower Capacity
!
WARNING
Exceeding the boat's maximum horsepower rating can cause serious injury or death. Overpowering the boat can affect boat control and flotation characteristics or break the transom. Do not install an engine that exceeds the boat's maximum power rating.
Do not overpower or overload your boat. Most boats will carry a required capacity plate indicating the maximum acceptable power and load as determined by the manufacturer following certain federal guidelines. If in doubt, contact your dealer or the boat manufacturer.

High‑Speed and High‑Performance Boat Operation
If your outboard is to be used on a high‑speed or high‑performance boat with which you are unfamiliar, we recommend that you never operate it at its high speed capability without first requesting an initial orientation and familiarization demonstration ride with your dealer or an operator experienced with your boat/outboard combination. For additional information, obtain a copy of our
Hi‑Performance Boat Operation booklet from your dealer, distributor, or Mercury Marine.
Propeller Selection
The propeller on your outboard is one of the most important components in the propulsion system. An improper propeller choice can significantly affect the performance of your boat and could result in damage to the outboard engine.
13
GENERAL INFORMATION
When choosing a propeller, a full selection of aluminum and stainless steel propellers specifically designed for your outboard are available through Mercury Marine. To view the entire product offering and find the correct propeller that is best suited for your application, visit www.mercmarinepropellers.com or see your local authorized Mercury dealer.
SELECTING THE CORRECT PROPELLER
An accurate tachometer for measuring engine speed is important in choosing the correct propeller.
Choose a propeller for your boating application that will allow the engine to operate within the specified full throttle operating range.
When operating the boat at full throttle under normal load conditions, the engine RPM should be in the upper half of the recommended full throttle RPM range. Refer to Specifications. If engine RPM is above that range, select a propeller of increased pitch in order to reduce engine RPM. If engine RPM is below the recommended range, select a propeller of reduced pitch to increase engine RPM.
IMPORTANT: To ensure proper fit, and performance, Mercury
Marine recommends the use of Mercury or Quicksilver branded propellers and mounting hardware.
14
GENERAL INFORMATION
Propellers are designated by the diameter, pitch, number of blades, and material. The diameter and pitch are stamped (cast) into the side or the end of the propeller hub. The first number represents the diameter of the propeller and the second number represents the pitch. For example, 14x19 represents a propeller with a 14 inch diameter and 19 inches of pitch.
a a Diameter b
22669 b Pitch ‑ Travel during one revolution
The following are some propeller basics that will help you determine the correct propeller for your boating application.
Diameter ‑ The diameter is the distance across the imaginary circle that is made when the propeller rotates. The correct diameter for each propeller has been predetermined for the design of your outboard. However, when more than one diameter is available for the same pitch, use a larger diameter for heavy boat applications and a smaller diameter for lighter applications.
Pitch ‑ The pitch is the theoretical distance, in inches, that a propeller travels forward during one revolution. Pitch can be thought of similar to gears in a car. The lower the gear, the faster the car will accelerate, but with lower overall top speed. Likewise, a lower pitch propeller will accelerate quickly, but top‑end speed will be reduced. The higher the propeller pitch the faster the boat will usually go; though typically slowing acceleration.
Determining the Correct Pitch size ‑ First, check the full throttle
RPM under normal load condition. If the full throttle RPM is within the recommended range, select a replacement or upgrade propeller with the same pitch as the current propeller.
15
GENERAL INFORMATION
• Adding 1 inch of pitch will reduce the full throttle RPM by 150 to 200
• Subtracting 1 inch of pitch will increase full throttle RPM by
150 to 200
• Upgrading from a 3‑blade propeller to a 4‑blade propeller will generally decrease full throttle RPM by 50 to 100
IMPORTANT: Avoid damage to the engine. Never use a propeller which allows the engine to exceed the recommended full throttle
RPM range when under normal full throttle operation.
PROPELLER MATERIAL
Most propellers manufactured by Mercury Marine are made from either aluminum or stainless steel. Aluminum is suitable for general purpose use and is standard equipment on many new boats.
Stainless steel is over five times more durable than aluminum and typically provides performance gains in acceleration and top end speed due to design efficiencies. Stainless steel propellers also come in a larger variety of sizes and styles that allow you to dial in the ultimate performance for your boat.
3 BLADE VS. 4 BLADE
Available in many sizes of both aluminum and stainless, 3 and
4‑blade propellers have unique performance characteristics. In general, 3‑blade propellers offer good all around performance and higher top speed than 4‑blade propellers. However, 4‑blade propellers are usually faster to plane and more efficient at cruising speeds, but lack the top end speed of a 3‑blade propeller.
Outboard Remote Control Models
The remote control connected to your outboard must be equipped with a start in neutral only protection device. This prevents the engine from starting when the shift is actuated in any position other than neutral.
16
GENERAL INFORMATION
!
WARNING
Starting the engine with the drive in gear can cause serious injury or death. Never operate a boat that does not have a neutral‑safety‑protection device.
26779
Remote Steering Notice
The steering link rod that connects the steering cable to the engine must be fastened utilizing self‑locking nuts. These self‑locking nuts must never be replaced with common nuts (non‑locking) as they will work loose and vibrate off, freeing the link rod to disengage.
!
WARNING
Improper fasteners or improper installation procedures can result in loosening or disengagement of the steering link rod. This can cause a sudden, unexpected loss of boat control, resulting in serious injury or death due to occupants being thrown within or out of the boat. Always use required components and follow instructions and torque procedures.

GENERAL INFORMATION
Lanyard Stop Switch
The purpose of a lanyard stop switch is to turn off the engine when the operator moves far enough away from the operator's position
(as in accidental ejection from the operator's position) to activate the switch. Tiller handle outboards and some remote control units are equipped with a lanyard stop switch. A lanyard stop switch can be installed as an accessory ‑ generally on the dashboard or side adjacent to the operator's position.
The lanyard is a cord usually 122 ‑ 152 cm (4 ‑ 5 feet) in length when stretched out, with an element on one end made to be inserted into the switch and a snap on the other end for attaching to the operator. The lanyard is coiled to make its at‑rest condition as short as possible to minimize the likelihood of lanyard entanglement with nearby objects. Its stretched‑out length is made to minimize the likelihood of accidental activation should the operator choose to move around in an area close to the normal operator's position. If it is desired to have a shorter lanyard, wrap the lanyard around the operator's wrist or leg, or tie a knot in the lanyard.

Read the following Safety Information before proceeding.
18
GENERAL INFORMATION
Important Safety Information: The purpose of a lanyard stop switch is to stop the engine when the operator moves far enough away from the operator's position to activate the switch. This would occur if the operator accidentally falls overboard or moves within the boat a sufficient distance from the operator's position. Falling overboard and accidental ejections are more likely to occur in certain types of boats such as low sided inflatables, bass boats, high performance boats, and light, sensitive handling fishing boats operated by a hand tiller. Falling overboard and accidental ejections are also likely to occur as a result of poor operating practices such as sitting on the back of the seat or gunwale at planing speeds, standing at planing speeds, sitting on elevated fishing boat decks, operating at planing speeds in shallow or obstacle infested waters, releasing your grip on a steering wheel or tiller handle that is pulling in one direction, drinking alcohol or consuming drugs, or daring high speed boat maneuvers.
While activation of the lanyard stop switch will stop the engine immediately, a boat will continue to coast for some distance depending upon the velocity and degree of any turn at shut down.
However, the boat will not complete a full circle. While the boat is coasting, it can cause injury to anyone in the boat's path as seriously as the boat would when under power.
We strongly recommend that other occupants be instructed on proper starting and operating procedures should they be required to operate the engine in an emergency (e.g. if the operator is accidentally ejected).
!
WARNING
If the operator falls out of the boat, stop the engine immediately to reduce the possibility of serious injury or death from being struck by the boat. Always properly connect the operator to the stop switch using a lanyard.
!
WARNING
Avoid serious injury or death from deceleration forces resulting from accidental or unintended stop switch activation. The boat operator should never leave the operator's station without first disconnecting the stop switch lanyard from the operator.
19
GENERAL INFORMATION
Accidental or unintended activation of the switch during normal operation is also a possibility. This could cause any, or all, of the following potentially hazardous situations:
• Occupants could be thrown forward due to unexpected loss of forward motion ‑ a particular concern for passengers in the front of the boat who could be ejected over the bow and possibly struck by the gearcase or propeller.
• Loss of power and directional control in heavy seas, strong current or high winds.
• Loss of control when docking.
Protecting People in the Water
WHILE YOU ARE CRUISING
It is very difficult for a person standing or floating in the water to take quick action to avoid a boat heading in his/her direction, even at slow speed.
21604
Always slow down and exercise extreme caution any time you are boating in an area where there might be people in the water.
Whenever a boat is moving (coasting) and the outboard gear shift is in neutral position, there is sufficient force by the water on the propeller to cause the propeller to rotate. This neutral propeller rotation can cause serious injury.
WHILE BOAT IS STATIONARY
!
WARNING
A spinning propeller, a moving boat, or any solid device attached to the boat can cause serious injury or death to swimmers. Stop the engine immediately whenever anyone in the water is near your boat.
20
GENERAL INFORMATION
Shift outboard into neutral and shut off the engine before allowing people to swim or be in the water near your boat.
Passenger Safety Message ‑ Pontoon Boats and
Deck Boats
Whenever the boat is in motion, observe the location of all passengers. Do not allow any passengers to stand or use seats other than those designated for traveling faster than idle speed. A sudden reduction in boat speed, such as plunging into a large wave or wake, a sudden throttle reduction, or a sharp change of boat direction, could throw them over the front of the boat. Falling over the front of the boat between the two pontoons will position them to be run over by the outboard.
BOATS HAVING AN OPEN FRONT DECK
No one should ever be on the deck in front of the fence while the boat is in motion. Keep all passengers behind the front fence or enclosure.
Persons on the front deck could easily be thrown overboard or persons dangling their feet over the front edge could get their legs caught by a wave and pulled into the water.
26782
!
WARNING
Sitting or standing in an area of the boat not designed for passengers at speeds above idle can cause serious injury or death. Stay back from the front end of deck boats or raised platforms and remain seated while the boat is in motion.
21
GENERAL INFORMATION
BOATS WITH FRONT MOUNTED, RAISED PEDESTAL
FISHING SEATS
Elevated fishing seats are not intended for use when the boat is traveling faster than idle or trolling speed. Sit only in seats designated for traveling at faster speeds.
Any unexpected, sudden reduction in boat speed could result in the elevated passenger falling over the front of the boat.
26783
Wave and Wake Jumping
Operating recreational boats over waves and wake is a natural part of boating. However, when this activity is done with sufficient speed to force the boat hull partially or completely out of the water, certain hazards arise, particularly when the boat reenters the water.
26784
The primary concern is the boat changing direction while in the midst of the jump. In such case, the landing may cause the boat to veer violently in a new direction. Such a sharp change in direction can cause occupants to be thrown out of their seats, or out of the boat.
22
GENERAL INFORMATION
!
WARNING
Wave or wake jumping can cause serious injury or death from occupants being thrown within or out of the boat. Avoid wave or wake jumping whenever possible.
There is another less common hazardous result from allowing your boat to launch off a wave or wake. If the bow of your boat pitches down far enough while airborne, upon water contact it may penetrate under the water surface and submarine for an instant.
This will bring the boat to a nearly instantaneous stop and can send the occupants flying forward. The boat may also steer sharply to one side.
Impact with Underwater Hazards
Reduce speed and proceed with caution whenever you drive a boat in shallow water areas, or in areas where you suspect underwater obstacles may exist which could be struck by the outboard or the boat bottom. The most important thing you can do to help reduce injury or impact damage from striking a floating or underwater object is to control the boat speed. Under these conditions, boat speed should be kept to a minimum planing speed of 24 to 40 km/h (15 to 25 MPH).
26785
Striking a floating or underwater object could result in an infinite number of situations. Some of these situations could result in the following:
• Part of the outboard or the entire outboard could break loose and fly into the boat.
23
GENERAL INFORMATION
• The boat could move suddenly in a new direction. Such a sharp change in direction can cause occupants to be thrown out of their seats or out of the boat.
• A rapid reduction in speed. This will cause occupants to be thrown forward, or even out of the boat.
• Impact damage to the outboard and/or boat.
Keep in mind, the most important thing you can do to help reduce injury or impact damage during an impact is control the boat speed.
Boat speed should be kept to a minimum planing speed when driving in waters known to have underwater obstacles.
After striking a submerged object, stop the engine as soon as possible and inspect it for any broken or loose parts. If damage is present or suspected, the outboard should be taken to an authorized dealer for a thorough inspection and necessary repair.
The boat should also be checked for any hull fractures, transom fractures, or water leaks.
Operating a damaged outboard could cause additional damage to other parts of the outboard, or could affect control of the boat. If continued running is necessary, do so at greatly reduced speeds.
!
WARNING
Operating a boat or engine with impact damage can result in product damage, serious injury, or death. If the vessel experiences any form of impact, have an authorized Mercury
Marine dealer inspect and repair the vessel or power package.
Exhaust Emissions
BE ALERT TO CARBON MONOXIDE POISONING
Carbon monoxide is present in the exhaust fumes of all internal combustion engines. This includes the outboards, sterndrives, and inboard engines that propel boats, as well as the generators that power various boat accessories. Carbon monoxide is a deadly gas that is odorless, colorless, and tasteless.
Early symptoms of carbon monoxide poisoning which should not be confused with seasickness or intoxication, include headache, dizziness, drowsiness, and nausea.
24
GENERAL INFORMATION
!
WARNING
Carbon monoxide poisoning can lead to unconsciousness, brain damage, or death. Keep the boat well ventilated while at rest or underway and avoid prolonged exposure to carbon monoxide.
GOOD VENTILATION
Ventilate passenger area, open side curtains or forward hatches to remove fumes.
21622
Example of desired air flow through the boat
POOR VENTILATION
Under certain running and/or wind conditions, permanently enclosed or canvas enclosed cabins or cockpits with insufficient ventilation may draw in carbon monoxide. Install one or more carbon monoxide detectors in your boat.
Although the occurrence is rare, on a very calm day, swimmers and passengers in an enclosed area of a stationary boat that contains or is near a running engine may be exposed to a hazardous level of carbon monoxide.

Selecting Accessories for Your Outboard
Genuine Mercury Precision or Quicksilver Accessories have been specifically designed and tested for your outboard. These accessories are available from Mercury Marine dealers.
IMPORTANT: Check with your dealer before installing accessories. The misuse of approved accessories or the use of nonapproved accessories can damage the product.
Some accessories not manufactured or sold by Mercury Marine are not designed to be safely used with your outboard or outboard operating system. Acquire and read the installation, operation, and maintenance manuals for all your selected accessories.
Safe Boating Suggestions
In order to safely enjoy the waterways, familiarize yourself with local and other governmental boating regulations and restrictions, and consider the following suggestions.
Use flotation devices. Have an approved personal flotation device of suitable size for each person aboard (it is the law) and have it readily accessible.
Do not overload your boat. Most boats are rated and certified for maximum load (weight) capacities (refer to your boat capacity plate). If in doubt, contact your dealer or the boat's manufacturer.
Perform safety checks and required maintenance. Follow a regular schedule and ensure that all repairs are properly made.
26
GENERAL INFORMATION
Know and obey all nautical rules and laws of the waterways. Boat operators should complete a boating safety course. Courses are offered in the U.S.A. by 1) the U.S. Coast Guard Auxiliary, 2) the
Power Squadron, 3) the Red Cross, and 4) your state boating law enforcement agency. Inquiries may be made to the Boating
Hotline, 1‑800‑368‑5647 or the Boat U.S. Foundation information number 1‑800‑336‑BOAT.
Make sure everyone in the boat is properly seated. Do not allow anyone to sit or ride on any part of the boat that was not intended for such use. This includes the back of seats, gunwales, transom, bow, decks, raised fishing seats, any rotating fishing seat; or anywhere that an unexpected acceleration, sudden stopping, unexpected loss of boat control, or sudden boat movement could cause a person to be thrown overboard or into the boat.
Never be under the influence of alcohol or drugs while boating (it is the law). Alcohol or drug use impairs your judgment and greatly reduces your ability to react quickly.
Prepare other boat operators. Instruct at least one other person on board in the basics of starting and operating the outboard, and boat handling, in case the driver becomes disabled or falls overboard.
Passenger boarding. Stop the engine whenever passengers are boarding, unloading, or are near the back (stern) of the boat. Just shifting the outboard into neutral is not sufficient.
Be alert. The operator of the boat is responsible by law to maintain a proper lookout by sight and hearing. The operator must have an unobstructed view particularly to the front. No passengers, load, or fishing seats should block the operator's view when operating the boat above idle speed.
Never drive your boat directly behind a water‑skier in case the skier falls. As an example, your boat traveling at 40 km/h (25 MPH) will overtake a fallen skier 61 m (200 ft) in front of you in 5 seconds.
Watch fallen skiers. When using your boat for waterskiing or similar activities, always keep a fallen or down skier on the operator's side of the boat while returning to assist the skier. The operator should always have the down skier in sight and never back up to the skier or anyone in the water.
27
GENERAL INFORMATION
Report accidents. Boat operators are required by law to file a
Boating Accident Report with their state boating law enforcement agency when their boat is involved in certain boating accidents. A boating accident must be reported if 1) there is loss of life or probable loss of life, 2) there is personal injury requiring medical treatment beyond first aid, 3) there is damage to boats or other property where the damage value exceeds $500.00, or 4) there is complete loss of the boat. Seek further assistance from local law enforcement.

TRANSPORTING
Trailering Boat/Outboard
Trailer your boat with the outboard tilted down in a vertical operating position.
If additional ground clearance is required, the outboard should be tilted up using an accessory outboard support device. Refer to your local dealer for recommendations. Additional clearance may be required for railroad crossings, driveways, and trailer bouncing.
28419
IMPORTANT: Do not rely on the power trim/tilt system or tilt support lever to maintain proper ground clearance for trailering.
The outboard tilt support lever is not intended to support the outboard for trailering.
Shift the outboard to forward gear. This prevents the propeller from spinning freely.
31
FUEL AND OIL
Fuel Recommendations
IMPORTANT: Use of improper gasoline can damage your engine. Engine damage resulting from the use of improper gasoline is considered misuse of the engine, and damage caused thereby will not be covered under the limited warranty.
FUEL RATINGS
Mercury Marine engines will operate satisfactorily when using a major brand of unleaded gasoline meeting the following specifications:
USA and Canada ‑ having a posted pump Octane Rating of 87 (R
+M)/2 minimum. Premium gasoline (92 [R+M]/2 Octane) is also acceptable. Do not use leaded gasoline.
Outside USA and Canada ‑ having a posted pump Octane Rating of 90 RON minimum. Premium gasoline (98 RON) is also acceptable. If unleaded gasoline is not available, use a major brand of leaded gasoline.
USING REFORMULATED (OXYGENATED) GASOLINES
(USA ONLY)
This type of gasoline is required in certain areas of the USA. The
2 types of oxygenates used in these fuels are alcohol (ethanol) or ether (MTBE or ETBE). If ethanol is the oxygenate that is used in the gasoline in your area, refer to Gasolines Containing
Alcohol .
These reformulated gasolines are acceptable for use in your
Mercury Marine engine.
GASOLINES CONTAINING ALCOHOL
If the gasoline in your area contains either methanol (methyl alcohol) or ethanol (ethyl alcohol), you should be aware of certain adverse effects that can occur. These adverse effects are more severe with methanol. Increasing the percentage of alcohol in the fuel can also worsen these adverse effects.
Some of these adverse effects are caused because the alcohol in the gasoline can absorb moisture from the air, resulting in a separation of the water/alcohol from the gasoline in the fuel tank.
32
FUEL AND OIL
The fuel system components on your Mercury Marine engine will withstand up to 10% alcohol content in the gasoline. We do not know what percentage your boat's fuel system will withstand.
Contact your boat manufacturer for specific recommendations on the boat's fuel system components (fuel tanks, fuel lines, and fittings). Be aware that gasolines containing alcohol may cause increased:
• Corrosion of metal parts
• Deterioration of rubber or plastic parts
• Fuel permeation through rubber fuel lines
• Starting and operating difficulties
!
WARNING
Fuel leakage is a fire or explosion hazard, which can cause serious injury or death. Periodically inspect all fuel system components for leaks, softening, hardening, swelling, or corrosion, particularly after storage. Any sign of leakage or deterioration requires replacement before further engine operation.
Because of possible adverse effects of alcohol in gasoline, it is recommended that only alcohol‑free gasoline be used where possible. If only fuel containing alcohol is available, or if the presence of alcohol is unknown, increased inspection frequency for leaks and abnormalities is required.
IMPORTANT: When operating a Mercury Marine engine on gasoline containing alcohol, storage of gasoline in the fuel tank for long periods should be avoided. Long periods of storage, common to boats, create unique problems. In cars, alcohol‑blend fuels normally are consumed before they can absorb enough moisture to cause trouble, but boats often sit idle long enough for phase separation to take place. In addition, internal corrosion may take place during storage if alcohol has washed protective oil films from internal components.
Oil Recommendation
Recommended Oil
Mercury or Quicksilver Premium 2-Cycle TC-W3
Outboard Oil
33
FUEL AND OIL
IMPORTANT: Oil must be NMMA certified TC‑W3 2‑Cycle oil.
Mercury or Quicksilver Premium TC‑W3 2‑Cycle oil is recommended for this engine. For added protection and lubrication, Mercury or Quicksilver Premium Plus TC‑W3 2‑Cycle oil is recommended. If Mercury or Quicksilver outboard oil is not available, substitute another brand of 2‑cycle outboard oil that is
NMMA Certified TC‑W3. Severe engine damage may result from use of an inferior oil.
Fuel Requirements for Engine Break‑in
Do not use pre‑mixed gas and oil during break‑in. The engine automatically receives extra oil during engine break‑in. Use a fresh supply of the recommended gasoline during engine break‑in and after engine break‑in.
Avoiding Fuel Flow Restriction
IMPORTANT: Adding components to the fuel supply system
(filters, valves, fittings, etc.) may restrict the fuel flow. This may cause engine stalling at low speed, and/or a lean fuel condition at high RPM that could cause engine damage.
Low Permeation Fuel Hose Requirement
Required for outboards manufactured for sale, sold, or offered for sale in the United States.
• The Environmental Protection Agency (EPA) requires that any outboard manufactured after January 1, 2009 must use low permeation fuel hose for the primary fuel hose connecting the fuel tank to the outboard.
• Low permeation hose is USCG Type B1‑15 or Type A1‑15, defined as not exceeding 15/gm²/24 h with CE 10 fuel at
23 °C as specified in SAE J 1527 ‑ marine fuel hose.
Filling Remote Oil Tank
Remove filler cap and fill with the specified oil. Oil tank capacity is
11.5 liters (3 gallons). Replace filler cap and tighten securely.
34
FUEL AND OIL
IMPORTANT: Always make sure the oil tank caps are threaded on tight. An air leak will prevent oil flow to the engine.
2723
Filling Engine Mounted Oil Reservoir Tank
NOTE: Filling this tank is only necessary if the oil level should ever drop and the low oil warning system is activated.
1. Remove the top cowl.
2. Loosen the fill cap on the engine oil reservoir tank. Run the engine until all the air has been vented out of the oil reservoir tank and tank is filled with oil to the point of overflow.
3. Re‑tighten the fill cap. Stop the engine and replace the top cowl.
29307
Filling Fuel Tank
!
WARNING
Avoid serious injury or death from a gasoline fire or explosion.
Use caution when filling fuel tanks. Always stop the engine and do not smoke or allow open flames or sparks in the area while filling fuel tanks.
Fill fuel tanks outdoors away from heat, sparks, and open flames.
Remove portable fuel tanks from boat to refill them.
35
FUEL AND OIL
Always stop engine before refilling tanks.
Do not completely fill the fuel tanks. Leave approximately 10% of the tank volume unfilled. Fuel will expand in volume as its temperature rises and can leak under pressure if the tank is completely filled.

The SmartCraft instrument package will also aid in Engine
Guardian diagnostics. The SmartCraft instrument package will display critical engine alarm data and potential problems.
Power Trim and Tilt
Your outboard has a trim/tilt control called power trim. This enables the operator to easily adjust the position of the outboard by pressing the trim switch. Moving the outboard in closer to the boat transom is called trimming in or down. Moving the outboard further away from the boat transom is called trimming out or up. The term trim generally refers to the adjustment of the outboard within the first 20° range of travel. This is the range used while operating your boat on plane. The term tilt is generally used when referring to adjusting the outboard further up out of the water. With the engine turned off, the outboard can be tilted out of the water. At low idle speed, the outboard can also be tilted up past the trim range to permit, for example, shallow water operation.

FEATURES AND CONTROLS
POWER TRIM OPERATION
With most boats, operating around the middle of the trim range will give satisfactory results. However, to take full advantage of the trimming capability there may be times when you choose to trim your outboard all the way in or out. Along with an improvement in some performance aspects comes a greater responsibility for the operator, and this is being aware of some potential control hazards.
The most significant control hazard is a pull or torque that can be felt on the steering wheel or tiller handle. This steering torque results from the outboard being trimmed so that the propeller shaft is not parallel to the water surface.
!
WARNING
Trimming the outboard beyond a neutral steering condition may result in a pull on the steering wheel or tiller handle and loss of boat control. Maintain control of the boat if trimming beyond a neutral steering condition.
Consider the following lists carefully.
1. Trimming in or down can:
• Lower the bow.
• Result in quicker planing off, especially with a heavy load or a stern heavy boat.
• Generally improve the ride in choppy water.
• Increase steering torque or pull to the right (with the normal right hand rotation propeller).
• In excess, can lower the bow of some boats to a point where they begin to plow with their bow in the water while on plane. This can result in an unexpected turn in either direction (called bow steering or oversteering) if any turn is attempted, or if a significant wave is encountered.
41
FEATURES AND CONTROLS
!
WARNING
Operating the boat at high speeds with the outboard trimmed too far under can create excessive bow steer, resulting in the operator losing control of the boat. Install the trim limit pin in a position that prevents excessive trim under and operate the boat in a safe manner.
• In rare circumstances, the owner may decide to limit the trim in. This can be accomplished by purchasing a stainless steel tilt pin from your dealer and inserting it in whatever adjustment hole in the transom brackets is desired. The nonstainless steel shipping bolt should not be used in this application other than on a temporary basis.
2. Trimming out or up can:
• Lift the bow higher out of the water.
• Generally increase top speed.
• Increase clearance over submerged objects or a shallow bottom.
• Increase steering torque or pull to the left at a normal installation height (with the normal right hand rotation propeller).
• In excess, can cause boat porpoising (bouncing) or propeller ventilation.
• Cause engine overheating if any cooling water intake holes are above the waterline.
TILTING OPERATION
To tilt outboard, shut off the engine and press the trim/tilt switch or auxiliary tilt switch to the up position. The outboard will tilt up until the switch is released or it reaches its maximum tilt position.
1. Engage the tilt support lever, by rotating knob to bring the support lever upward.
2. Lower outboard to rest on the tilt support lever.
42
FEATURES AND CONTROLS
3. Disengage the tilt support lever, by raising the outboard off the support lever and rotating the lever down. Lower the outboard.

SHALLOW WATER OPERATION
When operating your boat in shallow water, you can tilt the outboard beyond the maximum trim range to prevent hitting bottom.
1. Reduce engine speed below 2000 RPM.
2. Tilt outboard up. Make sure all the water intake holes stay submerged at all times.
3. Operate the engine at slow speed only. If engine speed exceeds 2000 RPM, the outboard will automatically return down to the maximum trim range.
44
OPERATION
Pre‑Starting Check List
• Operator knows safe navigation, boating, and operating procedures.
• An approved personal flotation device of suitable size for each person aboard and readily accessible (it is the law).
• A ring type life buoy or buoyant cushion designed to be thrown to a person in the water.
• Know the boat's maximum load capacity. Look at the boat capacity plate.
• Fuel supply OK.
• Oil supply (oil injection) OK.
• Arrange passengers and load in the boat so the weight is distributed evenly and everyone is seated in a proper seat.
• Tell someone where you are going and when you expect to return.
• It is illegal to operate a boat while under the influence of alcohol or drugs.
• Know the waters and area you will be boating; tides, currents, sand bars, rocks, and other hazards.
• Make inspection checks listed in Maintenance ‑ Inspection and Maintenance Schedule.

When using your outboard or having your outboard moored in freezing or near freezing temperatures, keep the outboard tilted down at all times so the gearcase is submerged. This prevents trapped water in gearcase from freezing and causing possible damage to the water pump and other components.
If there is a chance of ice forming on the water, the outboard should be removed and drained completely of water. If ice should form at the water level inside the outboard driveshaft housing, it will block water flow to the engine causing possible damage.
45
OPERATION
Operating in Saltwater or Polluted Water
We recommend that you flush the internal water passages of your outboard with fresh water after each use in salt or polluted water.
This will prevent a buildup of deposits from clogging the water passages. Refer to Maintenance ‑ Flushing the Cooling System.
If you keep your boat moored in the water, always tilt the outboard so the gearcase is completely out of water (except in freezing temperatures) when not in use.
Wash the outboard exterior and flush out the exhaust outlet of the propeller and gearcase with fresh water after each use. Each month, spray Mercury Precision or Quicksilver Corrosion Guard on external metal surfaces. Do not spray on corrosion control anodes as this will reduce the effectiveness of the anodes.
Operating at High Elevations
Your engine automatically compensates for high elevation changes. A different pitch propeller may help reduce some normal performance loss resulting from reduced oxygen in the air. Consult your dealer.
46
OPERATION
Setting Trim Angle While Running Engine at Idle
Speed
The exhaust relief hole on the outboard may become submerged if the outboard is trimmed full‑in while running at idle speed. This will cause exhaust restriction, rough idle, excessive smoke, and fouled spark plugs. If this condition exists, trim the outboard up until the exhaust relief hole is out of the water. The outboard should be lowered for accelerating from a standing start or from idle speed.
28423
Engine Break‑in Procedure
IMPORTANT: Failure to follow the engine break‑in procedures can result in poor performance throughout the life of the engine and can cause engine damage. Always follow break‑in procedures.
GASOLINE/OIL BREAK-IN MIXTURE
Do not use pre‑mixed gas and oil during break‑in. Oil from the oil injection system will supply adequate lubrication during engine break‑in.
BREAK-IN PROCEDURE
1. For the first hour of operation, allow the engine to warm up for
30‑60 seconds.
a. Run the engine at varied throttle settings, the majority of the time between 3000 and 4500 RPM or three‑quarter throttle.
47
OPERATION b. Change engine speed approximately every two minutes, and avoid continuous operation at idle speed for more than ten minutes. Short bursts of full throttle for periods up to ten seconds are acceptable.
c. Avoid trimming the outboard out (up) beyond a vertical trim position during operation.
NOTE: It is the driver's responsibility to always drive in a safe manner. Improper trim angle of the outboard when driving at the proper speed can be difficult and dangerous. The purpose of specifying trim angle is to help guide the operator in determining how to put the proper load on the engine.
2. For the next three hours of operation, change engine speed every ten minutes.
Starting the Engine
Before starting, read the pre‑starting check list, special operating instructions, and engine break‑in procedure in the Operation section.
NOTICE
Without sufficient cooling water, the engine, the water pump, and other components will overheat and suffer damage. Provide a sufficient supply of water to the water inlets during operation.
1. Lower the outboard to the vertical operating position. Make sure all cooling water intake holes are submerged.

19804
NOTE: The electronic starting system will automatically prime
(choke) the engine and increase idle speed for starting.
9. Check for a steady stream of water flowing out of the water pump indicator hole.
50
OPERATION
IMPORTANT: If no water is coming out of the water pump indicator hole, stop engine and check cooling water intake holes for obstruction. No obstruction may indicate a water pump failure or blockage in the cooling system. This condition will cause the engine to overheat. Have the outboard checked by your dealer.
Operating the engine while overheated will cause engine damage.
19805
Gear Shifting
IMPORTANT: Observe the following:
• Never shift outboard into gear unless engine speed is at idle.
• Do not shift outboard into reverse when the engine is not running.
• Your outboard has three gear shift positions to provide operation: Forward (F), Neutral (N), and Reverse (R).

Gearcase Lubrication
When adding or changing gearcase lubricant, visually check for the presence of water in the lubricant. If water is present, it may have settled to the bottom and will drain out prior to the lubricant, or it may be mixed with the lubricant, giving it a milky colored appearance. If water is noticed, have the gearcase checked by your dealer. Water in the lubricant may result in premature bearing failure or, in freezing temperatures, will turn to ice and damage the gearcase.
Examine the drained gearcase lubricant for metal particles. A small amount of metal particles indicates normal gear wear. An excessive amount of metal filings or larger particles (chips) may indicate abnormal gear wear and should be checked by an authorized dealer.

OUTBOARD INSTALLATION
Important Information
BEFORE STARTING THE ENGINE
NOTICE
Lack of oil pressure in the system can cause severe internal engine damage during start‑up. Prime the oil injection pump on new or rebuilt engines or after performing maintenance on the oiling system.
Refer to Priming the Oil Injection Pump for instructions.
FUEL REQUIREMENTS
Do not use pre‑mixed gas and oil in this engine. The engine automatically receives extra oil during engine break‑in. Use a fresh supply of the recommended gasoline during engine break‑in and after engine break‑in.
OIL RECOMMENDATION
Recommended Oil
Mercury or Quicksilver Premium 2-Cycle TC-W3
Outboard Oil
IMPORTANT: Oil must be NMMA certified TC‑W3 2‑Cycle oil.
Mercury or Quicksilver Premium TC‑W3 2‑Cycle oil is recommended for this engine. For added protection and lubrication, Mercury or Quicksilver Premium Plus TC‑W3 2‑Cycle oil is recommended. If Mercury or Quicksilver outboard oil is not available, substitute another brand of 2‑cycle outboard oil that is
NMMA Certified TC‑W3. Severe engine damage may result from use of an inferior oil.
Avoiding Fuel Flow Restriction
IMPORTANT: Adding components to the fuel supply system
(filters, valves, fittings, etc.) may restrict the fuel flow. This may cause engine stalling at low speed, and/or a lean fuel condition at high RPM that could cause engine damage.
82

OUTBOARD INSTALLATION
NOTICE
1. The outboard should be mounted high enough on the transom so the exhaust relief hole will stay at least 25.4 mm (1 in.) above the waterline when the engine is running at idle speed. Having the exhaust relief hole above the waterline will prevent exhaust restrictions. Exhaust restrictions will result in poor performance at idle.
2. Add 12.7 cm (5 in.) for XL models to the listed outboard mounting heights.
3. The mounting height of the outboard must not exceed 63.5 cm (25 in.) for
L models, 76 cm (30 in.) for XL models. Mounting the outboard higher may cause damage to the gearcase components.
Increasing the mounting height will usually:
• Reduce steering torque
• Increase top speed
• Increase boat stability
• Cause propeller to break loose during planing
Drilling Outboard Mounting Holes
IMPORTANT: Before drilling any mounting holes, carefully read
Determining Recommended Outboard Mounting Height and install outboard to the nearest recommended mounting height.

CHECKING BOAT TRANSOM CONSTRUCTION
IMPORTANT: Determine the strength of the boat transom. The outboard mounting locknuts and bolts should be able to hold
75 Nm (55 lb‑ft) of torque without the boat transom yielding or cracking. If the boat transom yields or cracks under this torque, the construction of the transom may not be adequate. The boat transom must be strengthened or the load carrying area increased.
b
18961 a Transom yielding under bolt torque a b Transom cracking under bolt torque
When first determining transom strength, use a dial torque wrench.
If the bolt or nut continues to turn without the torque reading on the dial increasing, it is an indication that the transom is yielding. The load area can be increased by using a larger washer or a transom reinforcement plate.
NOTE: The inside holes on the transom reinforcement plate are for the lower transom bolts and the outside holes are for the upper transom bolts.

Trim In Pin
OUTBOARD INSTALLATION
!
WARNING
Operating the boat at high speeds with the outboard trimmed too far under can create excessive bow steer, resulting in the operator losing control of the boat. Install the trim limit pin in a position that prevents excessive trim under and operate the boat in a safe manner.
Some boats, particularly some bass boats, are built with a greater than normal transom angle, which will allow the outboard to be trimmed further in or under. This greater trim under capability is desirable to improve acceleration, reduce the angle and time spent in a bow high boat during planing off, and in some cases, may be necessary to plane off a boat with aft livewells, given the variety of available propellers and height range of engine installations.
However, once on plane, the engine should be trimmed to a more intermediate position to avoid a bow‑down planing condition called plowing. Plowing can cause bow steering or oversteering and inefficiently consumes horsepower.

110
OUTBOARD INSTALLATION
The owner may decide to limit the trim in. This can be accomplished by purchasing a stainless steel tilt pin from your dealer and insert it in whatever adjustment hole in the transom brackets is desired. A non‑stainless steel shipping bolt should not be used in this application other than on a temporary basis.
