Sub-Section 02 (LEAK TEST)
LEAK TEST
GENERAL
A Sea-Doo Engine Leak Test Kit (P/N 295 500 352) is available to help diagnose engine problems such as engine seizure, poor performance, oil leakage, etc.
Before disassembling any components of the engine, it is important to perform a leakage test to determine which part is defective.
It is also very important after servicing the engine, even for a complete engine rebuilt, to perform another leakage test; at this stage, it may avoid further engine problems and minimizing the risk of having to remove and reinstall the engine again.
Static bench testing is the most effective way to conduct a leakage test. Inboard testing does not allow complete access to, and observation of all engine surfaces and should be avoided whenever possible.
On 717 engines, cylinders can not be verified individually due to leakage from one cylinder to another through a common intake manifold.
When installing hoses of the Engine Leak Test Kit, use the collars provided in the kit to ensure a proper sealing.
When pressurizing the engine, first confirm that the components of the Engine Leak Test Kit are not leaking by spraying a solution of soapy water on all hoses, connections, fittings, plates, etc. If there is a leak, bubbles will indicate leak location.
Three areas of the engine will be tested in sequence as per the diagnostic flow chart (see the end of this sub-section).
1. Engine Cooling System
2. Bottom End and Top End
3. Rotary Valve Shaft
NOTE: If a leak is found, it is important to continue testing as there is the possibility of having more than one leak. Continue pumping to compensate for the air lost to find another leak.
0
PREPARATION
Verify fuel system for leaks.
;
WARNING
If any fuel leak is found, do not start the engine. Correct the leak and wipe off any fuel spillage. Do not use electric powered tools unless fuel system has passed pressure test.
Disconnect battery BLACK negative cable.
;
WARNING
Always disconnect battery cables in the specified order, BLACK negative cable first.
Disconnect battery RED positive cable.
TESTING PROCEDURE
Engine Cooling System
Remove the tuned pipe.
Remove the exhaust manifold gasket and ensure the surface is cleaned.
Disconnect engine cooling hoses.
Install the appropriate exhaust manifold plate
( no. 1 for the 787 engine and no. 2 for 717 engines) from the Engine Leak Test Kit. Tighten plate using fasteners provided in the kit.
Use hoses provided in the kit and install them on the engine.
Install pump using reducer and appropriate tube(s) as necessary.

Activate pump and pressurize engine cooling system to 34 kPa (5 PSI).
Wait 3 minutes and check if pressure drops; if so, verify all testing components.
– If kit components are not leaking and pressure drops, verify all external jointed surfaces, temperature sensor and the O-ring between the spark plug area and the engine cylinder head cover. If none of these components are leaking, there is an internal leak and it can be detected with Bottom End and Top End testing.
Bottom End and Top End
Remove the carburetor(s) and gasket(s). Make sure the surface of the intake manifold (717 engines) or rotary valve cover (787 engine) are clean.
NOTE: With the BN-38 carburetor, intake manifold must be removed first to withdraw carburetor; Then, reinstall intake manifold to proceed with testing.
Install the intake plate(s) no. 3 with fasteners from the kit and tighten adequately.
On engines with the RAVE system, remove the
RAVE valves and gaskets.

– rotary valve cover
– engine plugs
– exhaust manifold
– intake manifold (717 engines)
– oil injection pump (717 engines)
Check also small oil injection pump lines and fittings; check for air bubbles or oil column going toward pump, which indicate a defective check valve.
If the above mentioned components are not leaking, block both oil hoses of the rotary valve shaft using hose pinchers.
NOTE: If leakage stops at this point, proceed with
Rotary Valve Shaft testing.
If there is still some leakage, remove the PTO flywheel to verify outer seal.
If no leak is found on the PTO side outer seal, remove magneto flywheel and verify crankshaft outer seals.
Proceed with the Rotary Valve Shaft testing if the crankshaft outer seals are not leaking.

GENERAL
The 2-stroke ROTAX engine rotates counterclockwise seen from the rear (PTO flywheel). It has a rotary valve to control opening and closing of intake.
-
CAUTION
No engine components can be interchanged between engines.
787 Engine Only
This engine is canted at a 30 degree angle, lowering the center of gravity of the watercraft. Cylinder exhaust ports are located on the same side of the intake, allowing a high volume tuned pipe design. This engine also features the RAVE system
(Rotax Adjustable Variable Exhaust). The RAVE system working in combination with the high volume tuned pipe offers a broader power band.
RAVE System
THEORY
For a 2-stroke-cycle engine to have high power capacity at high crankshaft speeds, a high volumetric or breathing efficiency is required and the fresh charge losses must be minimized. The result is achieved by opening the exhaust port early and utilizing the resonant effects of the tuned exhaust system to control fresh charge losses.
When an engine of this design is run at a medium speed, efficiency falls off quickly. The relatively high exhaust port effectively shortens the useful power stroke and because the exhaust system is tuned for maximum power, there is a large increase of fresh charge losses. As a result, the torque decreases along with a dramatic increase of the specific fuel consumption. Higher torque along with lower fuel consumption can be obtained at lower engine speeds if the time the exhaust port is open is shortened.
Bombardier-Rotax has patented a remarkably simple system to automatically change the exhaust port height based on pressure in the exhaust system.
Located above the exhaust port is a guillotinetype slide valve. This rectangular valve is connected by a shaft to a diaphragm which is working against the return spring. One small passage in the cylinder just outside the exhaust port allows exhaust gas pressure to reach the diaphragm.
To the outside of the return spring is a red plastic adjustment knob. Turning the adjustment in or out changes the preload on the return spring which, in turn, will change the RPM at which the RAVE valve opens and closes.

2. Diaphragm

As the throttle is opened and the engine begins producing more power, the pressure against the diaphragm will overcome the pressure of the return spring and the RAVE valve will open.

VALVE FULLY CLOSED
The RAVE valve does not allow an engine to make higher peak horsepower than an engine not so equipped, it can make moving the peak higher practical because of its effect on the rest of the power curve. Item 2 in the following figure is the power curve of an engine with the RAVE valve held fully open through its entire RPM range. Item
6 notes the peak power produced. That peak will not change if the exhaust port time of a similar engine without a RAVE valve was the same (with all other features equal).
Item 1 is the power curve of the engine with the
RAVE valve closed through its entire RPM range.
The shaded area (item 3) is the improvement in power at lower engine speeds that is gained because of the lower exhaust port. If the port remains at this height, however, the power would peak as noted in item 5. Raising the exhaust port at the proper RPM (item 7) will allow the engine peak power to continue to rise (item 6).
Item P1 in figure is the force of the return spring against the diaphragm. The exhaust pressure must be high enough to overcome this force before the valve begins opening. Item P2 is the pressure required to completely open the RAVE valve.
Between P1 and P2, the usable power curve of the engine is moving from power curve 1 to power curve 2. This transition takes place very rapidly at full throttle and from a practical standpoint can be considered to be instantaneous at item 7.
Gradual application of the throttle, however, will result in the RAVE valve opening much later.
If the RAVE valve opens too late, the engine will bog or hesitate momentarily as the RPM increases. Full peak performance (item 6) is still available.
From a functional point of view. It is better to have the valve open a bit early than a bit late.
RPM
A18C02A
MAINTENANCE
There are no wear parts anywhere in the system and there are no adjustments to be periodically checked. The only possible maintenance required would be cleaning of carbon deposits from the guillotine slide. Cleaning intervals would depend upon the user’s riding style and the quality of the oil used. Using FORMULA XP-S synthetic injection oil, we would suggest annual cleaning of the valve. If a customer uses a lower quality oil, more frequent cleaning may be required.
No special solvents or cleaners are required when cleaning the valve.
BORING PRECAUTION
In its stock configuration the RAVE valve guillotine has a minimum of 0.5 mm (.020 in) clearance to the cylinder bore measured at the center line of the cylinder. This is the minimum production clearance.
There is only a first oversize piston available for the 787 engine. That piston is 0.25 mm (.010 in) larger in diameter than the stock piston. When the oversize is installed, the guillotine will have a minimum clearance of 0.375 mm (.015 in) with the cylinder bore. This is the minimum operating clearance the guillotine should be used with.
Clearance less than 0.375 mm (.015 in) will require reworking of the guillotine to achieve the proper clearance and radius.

GENERAL
The following verification procedures such as clearance of rotary valve cover or rotary valve shaft gear backlash can be performed without removing engine from watercraft.
However engine must be removed from watercraft to work on rotary valve shaft/components.
Refer to ENGINE 03-03 for engine removal procedure.
Bottom end must be opened to remove rotary valve shaft. Refer to ENGINE 03-06.
INSPECTION ON WATERCRAFT
Remove carburetor(s). Refer to FUEL SYSTEM
05-04.
NOTE: On the 717D engine (SP model), rotary valve cover and carburetor are removed as an assembly.
1, Rotary Valve Cover
Unscrew 4 screws no. 2 and withdraw rotary valve cover and valve no. 13 .
Rotary Valve/Cover Clearance
The clearance between the rotary valve and the cover must be 0.30
±
0.05 mm (.012
±
.002 in).
NOTE: If the clearance is below 0.25 mm (.010 in) this could create an overheating situation and if the clearance is over 0.35 mm (.014 in) this could create a hard starting situation.
There is two methods to verify rotary valve
/cover clearance. One with a 45
°
feeler gauge, the other one with a solder.
45
°
FEELER GAUGE METHOD
Remove O-ring from rotary valve cover.
Remove intake manifold from rotary valve cover
(except 787 engine).
Reinstall cover in place WITHOUT its O-ring and torque screws to 20 N•m (15 lbf•ft).
Feeler gauge blade from 0.25 mm (.010 in) to 0.35
mm (.014 in) thickness should fit between rotary valve and cover.
Insert feeler gauge blade through cover inlet ports to verify clearance. At least verify clearance at two different places in each port.

F01D53A
1. 45
°
feeler gauge
If rotary valve cover clearance is out of specification, machine rotary valve cover seating surface or replace the cover.
SOLDER METHOD
Remove O-ring from rotary valve cover.
Use the following type of solder:
– rosin core
– diameter: 0.8 mm (.032 in)
– electronic application (available at electronic stores)
Install two solder pieces of 13 mm (1/2 in) long directly on rotary valve, one above and one below rotary valve gear. Apply grease to hold solder in position.
Reinstall cover in place WITHOUT its O-ring and torque screws to 20 N•m (15 lbf•ft).
Remove cover then clean and measure compressed solder thickness, it must be within the specified tolerance 0.30
±

Reverify the clearance.
At assembly the rotary valve timing must remain as per original setting.
NOTE: If rotary valve crankcase surface is worn, it is possible to have it reworked at the factory.
Contact your dealer or distributor.
Rotary Valve Shaft Gear Backlash
Remove PTO flywheel guard.
Remove spark plugs, rotary valve cover and valve.
Manually feel backlash at one position, then turn crankshaft about 1/8 turn and recheck. Continue this way to complete one revolution.
Backlash must be even at all positions. Otherwise overhaul engine to find which part is faulty (gear, rotary valve shaft or crankshaft with excessive deflection).

INSPECTION
1, Rotary Valve Cover
Inspect rotary valve cover for warpage. Small deformation can be corrected by surfacing with fine sand paper on a surface plate. Surface part against oiled sand paper.
8,9 Bearing
Inspect bearings. Check for scoring, pitting, chipping or other evidence of wear. Make sure plastic cage (on bigger bearing) is not melted. Rotate them and make sure they turn smoothly.
10, Gear
Visually check gear wear pattern. It should be even on tooth length all around. Otherwise it could indicate a bent shaft, check deflection. Replace gear if damaged.
Check for presence of brass filings in gear housing.
Rotary Valve Shaft Deflection
Deflection is measured with a dial gauge. Install rotary valve shaft in crankcase half, without its gear.
NOTE: End bearing must be in crankcase half.
Measure shaft deflection next to gear splines.
Deflection must not exceed 0.08 mm (.003 in).
Replace shaft as necessary.

CAUTION
All hoses and fittings of the cooling system have calibrated inside diameters to assure proper cooling of the engine. Always replace using appropriate Bombardier part number.
A Serial Cooling System is utilized on 717 and 787 engines, which offers an efficient cooling of the combustion chamber to prevent the possibilities of detonation.
1, Clamp
To cut or secure non-reusable Oetiker clamps of cooling system hoses, use pliers (P/N 295 000
070).
3, Elbow Fitting
Water injection used on exhaust system cools the exhaust gases to obtain maximum performance from the tuned pipe. The elbow fitting has a calibrated inside diameter to optimize water flow in tuned pipe.
The water injection also helps in reducing noise level and cools components of the exhaust system.
-
CAUTION
The elbow fittings are calibrated and can not be interchanged with one of a different size as severe engine damage could result.
The elbow fitting can be identified by using the number stamped onto the fitting or by measuring its inside diameter. Refer to the following illustration and chart.

4, Water Flow Regulator Valve
A water flow regulator valve has been developed for the 787 engine so that it can produce the maximum horsepower output and yet maintain the necessary diameter of the injection fitting at the tuned pipe head for unobstructed water flow.
The water flow regulator valve is mounted directly onto the muffler.
Adjustment
The water flow regulator valve has been calibrated at the factory and should not be modified.
NOTE: Water flow regulator valves ordered from the parts channel are also calibrated.
If the maximum engine speed can not be attained or if the engine has poor performance, the water flow regulator valve should be considered in the troubleshooting of the problem.
Mark the location of the red plastic adjustment screw with paint dots for reference purposes.
Fully tighten screw (clockwise) in valve cap.

3. Water injected into the muffler
NOTE: The water injected into the muffler is not regulated by the valve. A calibrated water injection fitting of 3.0 mm (.118 in) inside diameter limits water flow into the muffler.
The water flow regulator valve has a calibrated spring and a tapered needle which regulate the injected water in the tuned pipe.
-
CAUTION
Do not change the calibration of the spring, otherwise serious engine damage can occur.
At low speed, water pressure in the supply hose of the regulator valve is not sufficient to overcome the spring of the regulator valve; more water is being delivered to the injection fitting at the tuned pipe.
At higher speed, water pressure increases in the supply hose of the regulator valve and gradually overcomes the return spring of the regulator valve. Less water is being delivered to the injection fitting at the tuned pipe.

CIRCUIT
GENERAL
The cooling system is equipped with either a fitting spigot or a hose adapter depending upon the model for flushing purposes.
For flushing operation, a coupler hose is available
(unnecessary for models with the hose adapter) to connect to the fitting spigot. A garden hose is used to flush the whole system by backwash. For flushing procedure, refer to MAINTENANCE 01-
03.
For winterization of cooling system, refer to
MAINTENANCE 01-05.
Towing the Watercraft in Water
Special precautions should be taken when towing a Sea-Doo watercraft in water.
Maximum recommended towing speed is 24 km/h (15 MPH).
When towing your watercraft, pinch the water supply hose from the impeller housing to the engine with the Hose Pincher (large) P/N 529 030
400.
0
-
CAUTION
Failure to do this may result in damage to the engine. If you must tow a stranded watercraft in water and do not have a hose pincher be sure to stay well below the maximum towing speed of 24 km/h (15 MPH).
Snugly install the hose pincher on the water supply hose as shown in the following illustrations.

GENERAL
717 Engines
The digital Capacitor Discharge Ignition (CDI) system includes the following components:
Magneto
It is the primary source of electrical energy. It transforms magnetic field into electric current.
The flywheel contains 4 permanent magnets and spins around the generating coil. This electric current flows to the ignition coil (SP, GTS and HX models) or the Multi-Purpose Electronic Module
(GS, GSI and GTI models).

TYPICAL
SP, GTS and HX Models
The ignition coil performs two functions:
It has an integrated capacitor discharged ignition
(CDI) module, which controls the spark occurrence (ignition timing curve).
Every half revolution of the flywheel, a critical point occurs when the position of the magnets changes the polarity of the current flowing from the generating coil.
The CDI module detects the change of polarity and signals at the right time the primary winding of the ignition coil.
The secondary winding of the ignition coil steps up the voltage input to high voltage current for both spark plugs.
GS, GSI and GTI Models
The ignition coil steps up the voltage input from the Multi-Purpose Electronic Module to high voltage current for both spark plugs.
The ignition coil is located in the rear electrical box, on right side of watercraft.
Multi-Purpose Electronic Module
(MPEM)
The MPEM is directly powered by the battery. It has a micro-processor inside of its sealed case.
The MPEM is responsible of the following electrical functions:
– interpreting information
– distributing information

IGNITION TIMING PROCEDURE
Before checking ignition timing with a stroboscopic timing light (dynamic test), it is mandatory to scribe a timing mark on the PTO flywheel (static test) corresponding to the specific engine.
Also, the timing mark scribed on the PTO flywheel can be used to troubleshoot a broken magneto woodruff key.
NOTE: Do not use the factory mark found on the
PTO flywheel to check ignition timing or troubleshoot any problems.
-
CAUTION
The relation between the PTO flywheel mark position and crankshaft position may change as the PTO flywheel is screwed on the crankshaft. As an example, when the
PTO flywheel is reinstall on the crankshaft, it can slightly turns on the crankshaft when the engine is accelerated, even if it is properly torqued. This is enough to obtain a false ignition timing reading. Always verify PTO flywheel mark position before checking ignition timing with an appropriate timing light.
787 Engine
Normally ignition timing adjustment should not be required. It has been set at factory and it should remain correctly adjusted since every part is fixed and not adjustable. The only time the ignition timing might have to be changed would be when replacing the crankshaft, the magneto rotor, the trigger coil and the MPEM. If the ignition timing is found incorrect, you should first check for proper crankshaft alignment. This might be the indication of a twisted crankshaft.
With this DC-CDI system, the ignition timing can be checked with either the engine hot or cold. Also, the ignition timing is to be checked at 3500
RPM with the timing light.
Between 3000 and 4000 RPM, the spark advance does not change. So when checking ignition timing at 3500 RPM, a change in engine speed within
±
500 RPM will not affect the timing mark when checked with the timing light.

787 Engine
To correct the ignition timing, the data of the
MPEM is changed using the MPEM programmer
(P/N 295 000 127).
NOTE: For more information on the programmer, refer to its guide.
Through the MPEM programmer, the ignition timing can be advanced up to 3
°
or retarded up to 4
°
.
-
CAUTION
If the ignition timing is adjusted too advanced, this will cause serious damage to the engine.
The timing mark refer to the physical component position when the spark must occur. The MPEM must be synchronized with the mark. For instance, on a particular engine, the timing correction may need to be advanced to 2
°
so that the mark aligns with timing mark pointer tool. This is not the real spark advance, just a correction for the tolerances of the mechanical components.
Knowing that, you select with the programmer the higher or lower number to advance or retard the actual timing correction by referring to the following chart.

BOMBARDIER IGNITION TESTER
Use of Bombardier Ignition Tester
This tester (P/N 295 000 008) can verify generating coil (717 engines) and ignition coil of the ignition system.
A00E0EA
Always make sure that tester batteries are in good condition.
Test Condition
All tests are performed on watercraft at cranking speed with spark plugs installed.
Always proceed in the following order:
1. Connect tester P and N clip leads as indicated for each specific test.
2. Follow test procedure sequence.
3. Install cap over safety lanyard switch and crank engine until light turns on, or otherwise, for a maximum of 5 seconds.
4. After every test that lights the indicator lamp,
RESET the indicator circuit by depressing the reset button.
Analysis of Test Results
INDICATOR LAMP LIGHTS AT SPECIFIC
SETTING
Output is as specified. Test results should repeat
3 times. If readings do not repeat, output is erratic and cause should be investigated (loose connections or components, etc.).
INDICATOR LAMP LIGHTS AT LOWER
SETTING
This indicates that the output is less than that designed to operate in a satisfactory manner. However, before coming to the conclusion of a faulty condition be certain that correct engine cranking conditions were met before condemning the tested part.
INDICATOR LAMP DOES NOT LIGHT
One component is defective. Proceed as instructed to find defective component.
INTERMITTENT IGNITION PROBLEMS
In dealing with intermittent problems there is no easy diagnosis. For example, problems that occur only at normal engine operating temperature have to be tested under similar conditions.
In most cases of temperature and/or vibration failure, only parts replacement can solve the problem as most of these failures return to normal when engine is not running.
MULTIPLE PROBLEMS
There is always the possibility of more than one faulty part. If after a component has been replaced, the problem still persists, carefully repeat the complete test procedure to find the other faulty part.
SAFETY PRECAUTIONS www.SeaDooManuals.net

Heat Range
The proper heat range of the spark plugs is determined by the spark plugs ability to dissipate the heat generated by combustion.
The longer the heat path between the electrode tip to the plug shell, the hotter the spark plug operating temperature will be — and inversely, the shorter the heat path, the colder the operating temperature will be.
A “cold” type plug has a relatively short insulator nose and transfers heat very rapidly into the cylinder head.
Such a plug is used in heavy duty or continuous high speed operation to avoid overheating.
The “hot” type plug has a longer insulator nose and transfers heat more slowly away from its firing end. It runs hotter and burns off combustion deposits which might tend to foul the plug during prolonged idle or low speed operation.

Sub-Section 02 (IGNITION SYSTEM)
Fouling
Fouling of the spark plug is indicated by irregular running of the engine, decreased engine speed due to misfiring, reduced performance, and increased fuel consumption. This is due to a loss of compression. Other possible causes are: prolonged idling, or running on a too rich mixture due to a faulty carburetor adjustment or incorrect fuel.
The plug face of a fouled spark plug has either a dry coating of soot or an oily, glossy coating given by an excess either of oil or of oil with soot. Such coatings form a conductive connection between the center electrode and ground.
Spark Plug Analysis
2. Apply anti-seize lubricant over the spark plug threads to prevent possible seizure.
3. Hand screw spark plug into cylinder head and tighten with a torque wrench and a proper socket.

GENERAL
Magneto
The purpose of the charging system is to keep the battery at a full state of charge.
The magneto is the primary source of electrical energy. It transforms magnetic field into electric current (AC).
717 Engines
The magneto has a three-pole coil. Capacity is 160 watts.
SPX, GS, GSI, GSX, GTI, GTX and XP Models
Two 15 A fuses protect the charging system. The first one is located on the MPEM and the second one is located between the solenoid and the
MPEM.
All Models
If the battery is regularly discharged, check fuse condition.
The rectifier/regulator could be the culprit of a blown fuse. To check, simply disconnect the rectifier/regulator from the circuit.
If the fuse still burns, check for a defective wire.
787 Engine
The magneto has a 3 phase, “Y” wound stator on
18 poles. Capacity is 180 watts.
-
CAUTION
Do not use a higher rated fuse as this cause severe damage.
Rectifier/Regulator
717 Engines
A half-wave rectifier receives magneto AC current and transforms it into direct current (DC) to allow battery charging.
Included in the same unit, a regulator keeps voltage at a steady level (14.5 to 14.8 volts) to prevent any damage to components.
TESTING PROCEDURE
NOTE: First, ensure that battery is in good condition prior to performing the following tests.
787 Engine
A dual 1/2 wave series rectifier receives the magneto AC current and transforms it into direct current (DC) to allow battery charging.
Included in the same unit, a regulator keeps voltage at a steady level (14.5 to 14.8 volts) to prevent any damage to components.
Battery
The battery is the DC source for the electric starter, the Multi-Purpose Electronic Module and all accessories.
Fuse
Rectifier/Regulator
STATIC TEST: CONTINUITY
1. Due to internal circuitry, there is no static test available.
DYNAMIC TEST
Current Test
Proceed as follows:
– Start engine.
– Lay an inductive ammeter on positive cable of battery.
– Bring engine to approximately 5500 RPM.
Depending on battery charge, current reading should be approximately 4 amperes for the 717 engines or 5 amperes for the 787 engine. If not, check magneto output prior to concluding that rectifier is faulty.
SP, GTS and HX Models
A 15 A fuse protects the charging system.
Voltage Test
Proceed as follows:
– Start engine.
– Connect a DC voltmeter on battery posts.
– Bring engine to approximately 5500 RPM.
07-03-1 www.SeaDooManuals.net
Section 07 ELECTRICAL SYSTEM
Sub-Section 03 (CHARGING SYSTEM)
If voltmeter reads over 15 volts, regulator is defective. Replace it.
NOTE: If it is continually necessary to add distilled water to the battery, this indicates an over voltage situation, requiring replacement of the rectifier/regulator. If, on the other hand, the battery will not stay charged, the problem can be any of the charging circuit components. If these all check good, you would be accurate in assuming the problem to be in the rectifier/regulator.

Charging a used battery
◆
WARNING
Never charge battery while installed in watercraft.
For best results, battery should be charged when the electrolyte and the plates are at room temperature. A battery that is cold may not accept current for several hours after charging begun.
Do not charge a frozen battery. If the battery charge is very low, the battery may freeze. If it is suspected to be frozen, keep it in a heated area for about 2 hours before charging.
◆
WARNING
Always charge battery in a well ventilated area.
The time required to charge a battery will vary depending on some factors such as:
– Battery temperature: The charging time is increased as the temperature goes down. The current accepted by a cold battery will remain low. As the battery warms up, it will accept a higher rate of charge.
– State of charge: Because the electrolyte is nearly pure water in a completely discharged battery, it cannot accept current as well as electrolyte. This is the reason the battery will not accept current when the charging cycle first begins. As the battery remains on the charger, the current from the charger causes the electrolytic acid content to rise which makes the electrolyte a better conductor and then, the battery will accept a higher charging rate.
– Type of charger: Battery chargers vary in the amount of voltage and current that they can supply. Therefore, the time required for the battery to begin accepting measurable current will also vary.
Charging a very flat or completely discharged battery
The battery charger should have an adjustable charging rate. Variable adjustment is preferred, but a unit which can be adjusted in small increments is acceptable.
The battery charger must be equipped with an ammeter capable of accurately measuring current of less than 1 ampere.
Unless this procedure is properly followed, a good battery may be needlessly replaced.

If it is below 10 volts, the battery will accept current at very low rate, in term of milliamperes, because electrolyte is nearly pure water as explained above. It could be some time before the charging rate increases. Such low current flow may not be detectable on some charger ammeters and the battery will seem not to accept any charge.
– Exceptionally for this particular case, set the charger to a high rate.
NOTE: Some chargers have a polarity protection feature which prevents charging unless the charger leads are connected to the correct battery terminals. A completely discharged battery may not have enough voltage to activate this circuitry, even though the leads are connected properly.
This will make it appear that the battery will not accept a charge. Follow the charger manufacturer’s instruction on how to bypass or override this circuitry so that the charger will turn on and charge a low-voltage battery.
– Since the battery chargers vary in the amount of voltage and current they provide, the time required for the battery to accept measurable charger current might be up to approximately
10 hours or more.
– If the charging current is not up to a measurable amount at the end of about 10 hours, the battery should be replaced.
– If the charging current is measurable before the end or at the end of about 10 hours, the battery is good and charging should be completed in the normal manner as specified in Activation of a new battery .
– It is recommended that any battery recharged by this procedure be load tested prior to returning it to service.
Charging Two or More Batteries at a
Time
Connect all positive battery posts together and use a charger with a capacity (rated) equal to: number of battery to be charged multiply by 2 A.
For example: Charging 5 batteries at a time requires a 10 A rated charger (5 x 2 A = 10 A).

1. Oil sensor
The bottom of the sensor has a small reservoir with two small holes underneath to let the oil enter inside and one at the top to let the air enter allowing the oil to flow out.
When there is enough oil inside the oil tank (and therefore in the sensor reservoir), the sensor detects the liquid and the light DOES NOT turn on.
When the oil level goes at critical LOW level inside the oil tank (and therefore in sensor reservoir), the sensor detects the absence of liquid and the light TURNS ON.
To check the oil sensor, unplug its connector and pull sensor out of oil tank.
Using an ohmmeter, check the continuity between the BLUE and BLUE/BLACK terminals.
When sensor is out of oil tank and its reservoir is empty, resistance must be infinite (open circuit).
NOTE: Wait about 15-20 seconds before taking any reading to give the oil enough time to flow out or inside sensor reservoir.
Soak sensor in oil so that its reservoir fills up.
Maximum resistance should be approximately

Sub-Section 06 (DIGITALLY ENCODED SECURITY SYSTEM)
DIGITALLY ENCODED SECURITY
SYSTEM
GENERAL
The Digitally Encoded Security System (DESS) features an anti-start protection against unauthorized use of the watercraft.
The following components are specially designed for this system: Multi-Purpose Electronic Module
(MPEM), safety lanyard cap and safety lanyard switch.
The safety lanyard cap has a magnet and a ROM chip. The chip has a unique digital code.
The DESS circuitry in the watercraft MPEM is activated at the factory. Therefore, a safety lanyard must be programmed to start the engine.
NOTE: Actually, it is the memory of the MPEM which is programmed to recognize the digital code of the safety lanyard cap. This is achieved with the MPEM programmer (P/N 295 000 127).
Refer to its guide to program a safety lanyard.
The system is quite flexible. Up to eight safety lanyards may be programmed in the memory of the watercraft MPEM. They can also be erased.
NOTE: If desired, a safety lanyard can be used on any watercraft of the same model year equipped with the DESS.
The memory of the MPEM is permanent. If the battery is disconnected, no information is lost.
The memory of the MPEM has also two selfdiagnostic modes.
When ordering a new MPEM from the regular parts channel, the DESS circuitry will be activated.

• Use programmer and program a safety lanyard. This code can occur only when you receive a new MPEM from the factory and no key has ever been programmed.
• Check safety lanyard cap condition with the MPEM programmer.
Replace safety lanyard if reported defective.
• Check switch wiring harness.
2 long beeps
• Mixed wires at safety lanyard switch connectors or bad connections.
• Wrong safety lanyard or bad connection of the DESS wires.
3 short beeps • Wiring harness of DESS switch is grounded or there is a short circuit.
• Use the safety lanyard that has been programmed for the watercraft. If the problem is not resolved, check safety lanyard cap condition with the
MPEM programmer. Replace safety lanyard if reported defective.
• Check wiring harness and safety lanyard switch.
If you need to listen again the coded beeps, remove safety lanyard and repeat the procedure to activate the diagnostic mode.
If there is more than one problem, the MPEM will send only one error code. When the problem is solved, the MPEM will send a second code and so on until all problems are resolved.

Pay attention to the following conditions that will denote a defective shock absorber:
– A skip or a hang back when reversing stroke at mid travel.
– Seizing or binding condition except at extreme end of either stroke.
– Oil leakage.
– A gurgling noise, after completing one full compression and extension stroke.
Renew if any defects are present.

DECALS REPLACEMENT
Removal
Using a heat gun warm up one end of decal for a few seconds until decal can roll off when rubbing with your finger.
Pull decal slowly and when necessary apply more heat to ease removal on the area that has to be peeled off.
If decal tears while pulling off, it has to be heated for a few seconds longer. If decal tends to stretch while pulling off, stop heating and wait a few seconds to let it cool, then peel it off.
Installation
There are 2 types of decals used on watercraft.
One has a protective film on back side and the other has a protective film on both sides. They are used on 3 types of materials; plastic, gelcoat and metal.
DECALS HAVING A PROTECTIVE FILM ON
BACK SIDE ONLY
These decals usually contain written information
(ex.: warning) and are used on gelcoat or metal.
Clean surface with a good solvent such as
ACRYLICLEAN DX 330 from PPG or equivalent
(refer to manufacturer instructions).
Using a pencil and the decal as a template, mark the area where decal will be located.
Remove half of the decal back protective film and align decal with marks. Start sticking it from center and remove the other half of the film to stick it completely. Carefully squeegee decal beginning at center and working outward using, firm, short, overlapping strokes.
DECALS HAVING A PROTECTIVE FILM ON
BOTH SIDES
These decals usually contain graphics and are used on gelcoat or plastic.
INSTALLATION ON GELCOAT
Clean surface with a good solvent such as ACRY-
LI-CLEAN DX 330 from PPG or equivalent (refer to manufacturer instructions).
For best result apply an activator (P/N 293 530
036) to prepare the surface using a clean cloth.
After a few seconds, when the activator evaporates, the surface is ready.
Using a pencil and the decal as a template mark the area where decal will be located.
For better adhesion a dry application is recommended, however, to ease decal installation a mild solution of soapy water can be sprayed over surface where decal will be installed.
Remove back protective film from decal and align decal with marks. When well aligned squeegee decal beginning at center and working outward using firm, short, overlapping strokes.
Remove front protective film once decal has adhered to hull.

HULL AND BODY REPAIR
General
Gelcoat is the smooth and durable cosmetic finish which coats the fiberglass hull and body of a Sea-
Doo watercraft. It also provides a protective barrier against water and sun. It consists of a mixture of resin, pigment (coloring), fillers, monomers and catalyst which is sprayed into the mold.
The body and hull of the Sea-Doo are constructed of chopped fiberglass, saturated with resin. It is sprayed on the layer of gelcoat along with pieces of fiberglass mat, cloth and woven rowing which are added at required areas. This type of construction is very accommodating for high quality repairs. With patience, the proper techniques and materials, a damaged area can be restored to an original finish.
NOTE: Fiberglass repair kit is available through automotive or marine suppliers. Gelcoat repair kits are available through regular channel.
;
WARNING
Protect skin, wear gloves when in contact with resin, hardeners and gelcoat. A barrier skin cream may also be used. Do not expose area to open flame or lit cigarette. Some of the materials are flammable. Protect eyes, wear safety glasses when grinding, sanding or spraying. Use a dust mask when sanding or grinding. When spraying wear a respirator or paint mask. Always read warning labels on products.
Air Bubbles
Possible Cause:
– Air pocket trapped between layers of laminate and gelcoat.
PREPARATION OF SURFACE
Remove all of the damaged gelcoat surrounding the air bubble with a putty knife or preferably a carbide grinding tip. Make sure all loose and weak areas are completely removed. Sand a small area of the gelcoat surface with 220-grit sandpaper. If needed, sand the cavity itself. These areas must have a rough surface to allow the gelcoat putty to bond properly.
FILLING THE CAVITY
The prepared surface must be cleaned with acetone on a cloth. Use the Bombardier gelcoat repair kit (P/N 295 500 100). Follow the mixing instructions in the kit when preparing the gelcoat putty.
Carefully mix the required amount while making sure there are no air bubbles in the mixture. With a putty knife, fill the repair area and cover with plastic film. Curing time may depend on temperature, amount of putty and percentage of catalyst.
After 2 hours, press lightly on the surface with fingers to test the hardness. When the area becomes hard, remove the plastic film.

Section 11 HULL/BODY
Sub-Section 02 (ADJUSTMENT AND REPAIR)
SANDING
Begin block sanding the patch with 320-grit sandpaper until you come close to the original surface.
Remove dust with a water soaked cloth and continue sanding with a 400-grit wet paper. Finish wet sanding with a 600-grit to remove deeper scratches. If needed you can wet sand with finer grit paper such as 1000-grit.
BUFFING AND WAXING
Buff the surface using a heavy duty polisher with a buffing pad. Make sure the pad is free of dirt or you may damage the gelcoat. Carefully begin buffing with a white medium compound. Finish off using a fine compound. While buffing, pay close attention to avoid overheating the surface.
Blisters
Possible Causes:
– Insert catalyst.
– Improper catalyst/gelcoat ratio.
A blister is a visible bump on the watercraft surface that may not necessarily come right through the gelcoat layer. In the case of only a few blisters, follow the same repair procedure as for air bubbles. If they are numerous and in close concentration, spray liquid gelcoat to achieve proper repair.
This procedure is covered in Minor Gelcoat Fractures .
Minor Gelcoat Fractures
Possible Causes:
– Flexing of fiberglass laminate.
– Gelcoat thickness.
– Direct result of impact.
In case of fractures which have not penetrated past the gelcoat layer, the repair concerns the gelcoat only. If flex cracking or impact are evident, then additional reinforcement may be necessary.
This subject will be covered in Compound Fractures.
PREPARING THE SURFACES
Small Fractures
Open the cracks up with a sharp triangular can opener or preferably a carbide tipped die grinder.
The V groove will provide a good bonding area for the gelcoat. With 220-grit sandpaper, sand the sides of the notched out areas.
Numerous Fractures
Using a grinder with a 24-grit disk, remove the gelcoat. Sand the area edge with 220-grit sandpaper.
FILLING THE REPAIR AREA
Small Fractures
Refer to the same procedure as in the Air Bubbles .
Numerous Fractures Over Large Surface:
Prepare the area for spray application of liquid gelcoat. Wipe down the surface with acetone.
Mask the area off to protect the watercraft from overspray.
Mix the needed quantity of gelcoat and catalyst according to suppliers recommendations. The gelcoat can be thinned with acetone up to 10%. If it needs more consistency you can add cabosil.
Make sure that the air supply is free of oil, dirt and water.
Test spray the gelcoat mixture on paper to verify its consistency and pattern. You may have to apply 5 or 6 coats to cover the area properly. Overlap each coat further than the last, leaving at least 30 seconds between passes. Avoid trying to coat the surface with only a few heavy coats, this will not allow the gelcoat to dry properly.
Apply a coat of polyvinyl alcohol to seal off the air and protect the gelcoat surface from dust. PVA speeds up the curing process because gelcoat will not cure properly when exposed to air.
SANDING
Wash the polyvinyl alcohol off with water. Depending on the size of the area repaired, you can either block sand as per previous procedure or you may use an air sander. Sand the surface down with progressively finer grits of sandpaper until the desired finish is achieved.
BUFFING AND WAXING
Buff the surface using a heavy duty polisher with a buffing pad. Make sure the pad is free of dirt or you may damage the gelcoat. Carefully begin buffing with a white medium compound. Finish off using a fine compound. While buffing, pay close attention to avoid overheating the surface.

Section 11 HULL/BODY
Sub-Section 02 (ADJUSTMENT AND REPAIR)
Compound Fractures
Possible Causes:
– Thickness of fiberglass laminate.
– Direct result of impact.
Compound fractures are those that have gone past the gelcoated surface and in through the layers of fiberglass laminate. Two types of repairs have to be performed. The first is to restore the structural integrity of the damaged area. Fracture types can vary from a simple crack to a large hole.
Usually, fiberglass reinforcement becomes necessary, especially if the fracture can be attributed to weakness. The final part of the repair is the gelcoating, which cannot be done until the interior and exterior laminate surfaces have been repaired.
Outside
Remove the damaged gelcoat and fiberglass with a 24-grit disk using a power sander. Grind outward at least 2 inches from the fracture to allow the patch to bond to strong material. Cut enough pieces of fiberglass mat necessary to build up the area. The pieces should be cut so they overlap each other by at least a half inch. For a smoother finish, the last layer should be fiberglass cloth. If the fracture is small enough all you may have to do is fill the area with an epoxy filler.
Inside
For the interior repair, you can grind more. This will allow for more fiberglass material which will strengthen the area. If the fracture opening is too large after surface preparation, you may need a backing support to cover the opening. Cut alternating pieces of fiberglass mat and cloth in overlapping sizes.
PATCHING THE REPAIR AREA
Outside
The outside should be done first. Wipe clean the area with acetone on a cloth, then mask off area.
For a small crack use an epoxy filler in the same way you would use Bombardier’s gelcoat repair putty. When laying up a larger area you will use mat, cloth and fiberglass resin and hardener. Use a clean container to mix the resin, mix only what you will need. Follow the recommended catalyst ratio.
www.SeaDooManuals.net
Using a clean paintbrush, brush the mixed resin on the surface. Place the smallest piece of mat over the fracture and then wet out the mat. Follow with the remaining pieces of mat and final layer of cloth. While wetting the pieces make sure you work the air bubbles out and saturate all the pieces evenly. Try to work quickly, you may only have 15 or 20 minutes. You may clean the brush with acetone.
Wait until the repair has hardened before moving on to the interior repair. If the size of the opening is too large for the pieces to maintain the proper shape, you will have to use a backing support. It is a shaped piece of cardboard that fits flush to the interior surface and has a plastic layer on the repair side. It is held in place by tape or a support.
Inside
Wipe down the area with acetone on a cloth. Apply the same procedure as for outside repair when laminating the alternating pieces of fiberglass material. If a backing support was used, remove it before starting the repair. After the area has hardened, remove sharp edges of material from surface. If required paint the surface.
SANDING
Outside
This surface will have to be prepared for application of gelcoat. The size of the area will determine the gelcoating procedure to be used. Refer to the repair procedure for minor gelcoat fractures.
