FUEL AND OIL
GASOLINESuzuki highly recommends that you use alco-hol-free unleaded gasoline whenever possible,with a minimum pump octane rating of 87((R+M)/2 method). In some areas, the onlyfuels that are available are oxygenated fuels.Oxygenated fuels which meet the minimumoctane requirement and the requirementsdescribed below may be used in your outboardmotor without jeopardizing the New OutboardMotor Limited Warranty.
NOTE:Oxygenated fuels are fuels which contain oxy-gen-carrying additives such as MTBE or alco-hol.
Suzuki recommends that you install a water-separating fuel filter assembly between yourboat’s fuel tank(s) and outboard motor(s). Fuelfiltration systems of this type will help preventwater that may be present in your boat’s fueltank(s) from contaminating your motor’s elec-tronic fuel injection system. Water contamina-tion can cause poor engine performance andcan also cause damage to the electronic fuelinjection system components.Your Authorized Suzuki Marine Dealer can pro-vide you advice about water-separating fuel fil-ter systems and installation.
NOTICE
Use of leaded gasoline can cause enginedamage. Use of improper or poor qualityfuel can affect performance and maydamage your motor and fuel system.
Use only unleaded gasoline. Do not usefuel having lower than the recommendedoctane, or fuel that may be stale or con-taminated by dirt/water etc.
Gasoline Containing MTBEUnleaded gasoline containing MTBE (MethylTertiary Butyl Ether) may be used in your out-board motor if the MTBE content is not greaterthan 15%. This oxygenated fuel does not con-tain alcohol.
Gasoline/Ethanol BlendsBlends of unleaded gasoline and ethanol (grainalcohol), also known as gasohol, may be usedin your outboard motor if the ethanol content isnot greater than 10%.
Gasoline/Methanol BlendsAvoid using blends of unleaded gasoline andmethanol (wood alcohol) whenever possible.DO NOT USE fuels containing more than 5%methanol under any circumstances. Fuel sys-tem damage or outboard motor performanceproblems resulting from the use of such fuelsare not the responsibility of Suzuki and may notbe covered under the New Outboard Motor Lim-ited Warranty.
Fuel containing 5% or less methanol may besuitable for use in your outboard motor if theycontain cosolvents and corrosion inhibitors.
Fuel Pump LabelingIn some states, pumps that dispense oxygen-ated fuels are required to be labeled for the typeand percentage of oxygenate, and whetherimportant additives are present. Such labelsmay provide enough information for you todetermine if a particular blend of fuel meets therequirements listed above. In other states,pumps may not be clearly labeled as to the con-tent or type of oxygenate and additives. If youare not sure that the fuel you intend to usemeets these requirements, check with the ser-vice station operator or the fuel suppliers.
NOTE:• Be sure that any oxygenated fuel blend you
use has octane ratings of at least 87 pumpoctane ((R+M)/2 method).
• If you are not satisfied with the driveability orfuel economy of your outboard motor whenyou are using a gasoline/alcohol blend, youshould switch back to unleaded gasoline con-taining no alcohol.
https://www.boat-manuals.com/

• If engine pinging is experienced, substituteanother brand, as there are differencesbetween brands.
• Unleaded gasoline will extend spark plug life.
WARNING
Gasoline is extremely flammable andtoxic. It can cause a fire and can be haz-ardous to people and pets.
Always take the following precautionswhen refueling:• Never permit anyone other than an
adult to refill the fuel tank.• If you use a portable fuel tank, always
stop the motor and remove the fueltank from the boat to refill it.
• Do not fill the fuel tank all the way tothe top or fuel may overflow when itexpands due to heating by the sun.
• Be careful not to spill fuel. If you do,wipe it up immediately.
• Do not smoke, and keep away fromopen flames and sparks.
NOTICE
Gasoline kept in the fuel tank for longperiods of time will produce varnish andgum, which can damage the engine.
Always use fresh gasoline.
NOTICE
Fuels containing alcohol can cause paintdamage, which is not covered under theNew Outboard Motor Limited Warranty.
Be careful not to spill fuel containingalcohol while refueling. If fuel is spilled,wipe it up immediately.
ENGINE OIL
Oil quality is a major contributor to yourengine’s performance and life. Always selectgood quality engine oil.Suzuki recommends the use of SAE 10W-40SUZUKI MARINE 4-CYCLE ENGINE OIL. IfSUZUKI MARINE 4-CYCLE ENGINE OIL is notavailable, select a NMMA certified FC-W oil orgood quality 4-cycle motor oil from the followingchart according to the average temperatures inyour area.
NOTE:In very cold weather (below 5°C (41°F), useSAE (or NMMA FC-W) 5W-30 for easier start-ing and smooth operation.
GEAR OILSuzuki recommends the use of SUZUKIHYPOID GEAR OIL. If it is not available, useSAE 90 hypoid gear oil which is rated GL-5under the API classification system.

USE OF ELECTRICAL ACCESSORIES
The amount of power (12V DC) available foraccessories depends on the operating condi-tion of the motor. For getting a detailed informa-tion, please inquire of your authorized SuzukiMarine Dealer.
NOTE:Use of too much power for electrical accesso-ries under certain operating conditions cancause the battery to discharge.
PROPELLER SELECTION AND INSTALLATION
PROPELLER SELECTIONIt is essential to use a propeller on your out-board motor that is properly matched to yourboat’s operating characteristics. The speed ofthe engine when you operate your boat at fullthrottle depends on the propeller you use.Excessive engine speed can seriously damagethe motor, while low engine speed at full throttlewill adversely affect the performance. Youroperating load will also affect propeller selec-tion. Smaller loads generally require larger-pitch propellers; larger loads generally requiresmaller-pitch propellers. Your authorized SuzukiMarine Dealer will assist you in selecting a suit-able propeller for your boat.
You can determine if your propeller is appropri-ate for use with your boat by using a tachome-ter to measure engine speed when operatingyour boat at full throttle, under minimum loadconditions. If you are using an appropriate pro-peller, the engine speed will be within the fol-lowing range:
If the engine speed is not within this range, con-sult your authorized Suzuki Marine Dealer todetermine which propeller size is best for you.
If you change propellers, be sure to perform theabove check again, to confirm that the enginespeed under full throttle is within the specifiedrange.
NOTICE
Installing a propeller with either too muchor too little pitch will cause incorrectmaximum engine speed, which mayresult in severe damage to the motor.
Ask your authorized Suzuki marinedealer to assist you in selecting a suit-able propeller for your boat.

PROPELLER INSTALLATION
To install a propeller on your outboard motor,use the following procedure:
1. Coat the propeller shaft splines 1 liberallywith Suzuki water resistant grease to helpprevent corrosion.
2. Place the stopper 2 on the shaft.3. Align the propeller 3 with the propeller shaft
splines and slide the propeller onto the shaft.4. Place the spacer 4 and washer 5 on the
shaft.5. Install the propeller nut 6 and tighten it with
a torque wrench to 50 – 60 N·m (5.0 – 6.0kg-m/36.0 – 43.5 lb-ft).
6. Align the grooves in the propeller nut withthe hole in the shaft, then insert the cotterpin 7 and bend the pin ends over to lock it inplace.
To remove the propeller, reverse the above pro-cedure.
WARNING
Failure to take proper precautions wheninstalling or removing the propeller canresult in severe personal injury.
When installing or removing the propeller:• Always shift into “Neutral” and remove
the emergency stop switch lock plateso that the motor cannot be startedaccidentally.
• Wear gloves to protect hands, and“lock” the propeller by placing a blockof wood between the blades and theanti-cavitation plate.
ADJUSTMENTS
TRIM ANGLE ADJUSTMENT
To help maintain steering stability and goodperformance, always maintain the proper trimangle as shown in the illustration. The appropri-ate trim angle varies depending on the combi-nation of the boat, engine, and propeller, as wellas operating conditions.
Make a test run in the boat to determine if thetrim angle needs to be adjusted. Adjust the trimangle using the Power Trim and Tilt system.Refer to the POWER TRIM AND TILT section.
If you still cannot achieve good performance,there may be a problem with engine mountingheight. Consult your dealer for assistance.
• Trim angle too small (Boat tends to “plow”)
• Trim angle too large (Boat tends to“porpoise”)
• Proper trim angle
https://www.boat-manuals.com/
13
WARNING
Trim angle greatly affects steering stabil-ity. If the trim angle is too small, the boatmay “plow” or “bow steer”. If the trimangle is too large, the boat may “chinewalk” from side to side or “porpoise” upand down. These conditions, which resultin loss of steering control, can causeoccupants to be thrown overboard.
Always maintain proper trim angle basedon the combination of your boat, engine,and propeller, as well as operating condi-tions.
WARNING
When the motor is tilted beyond the maxi-mum trim position, the swivel bracket willnot have side support from the clampbracket and the tilt system will be unableto cushion the engine if the lower unitstrikes an obstruction. This could lead tooccupant injury.
Do not operate the engine above 1500 r/min or operate the boat in a planing atti-tude with the motor tilted beyond themaximum trim position.
Trim range
Tilt range
TRIM TAB ADJUSTMENT
This adjustment is used to compensate for thepossible tendency of your boat to veer slightlyto port or starboard. This tendency could bedue to such things as propeller torque, motormounting position, etc.
To adjust the trim tab:1. Loosen the bolt A that holds the trim tab in
place.
NOTICE
If you operate the boat with the motortrimmed beyond the maximum trim posi-tion, the water intake holes may be abovethe water line, causing severe enginedamage due to overheating.
Never operate the boat with the motortrimmed beyond the maximum trim posi-tion.

Marine-grade water resistant grease
Propeller shaft
Trim ram pad
Swivel bracketMarine-grade water resistant grease(Grease Gun)
Steering bracket
Your authorized Suzuki Marine Dealer may alsohave additional recommendations due toregional climate or operating conditions.Please consult him for advice.
CORROSION PREVENTIONANODESThe motor is protected from exterior corrosionby anodes. These anodes control electrolysisand help prevent corrosion. The anodes willcorrode in place of the parts they are protect-ing. You should periodically inspect each of theanodes and replace them when 2/3 of the metalhas corroded away.
In certain areas of the country, the water isunusually harsh on metal. Additional anti-corro-sion measures may be helpful under those con-ditions. Consult your authorized Suzuki MarineDealer for details.
NOTICE
If anodes are not properly maintained,underwater aluminum surfaces (such asthe lower unit) will suffer galvanic corro-sion damage.
• Periodically inspect anodes to makesure they have not become detached.
• Do not paint anodes, as this will renderthem ineffective.
• Periodically clean anodes with a wirebrush to remove any coating whichmight decrease their protective ability.
https://www.boat-manuals.com/
44
BONDING WIRESBonding wires are used to electrically connectthe engine components so they exist in a com-mon ground circuit. This allows them to be pro-tected against electrolysis by the anodes.These wires and their terminals should bechecked periodically to be sure they have notbeen damaged.
BATTERY
If you are using a maintenance-free battery,inspect the window area according to theinstructions on the battery to make sure the bat-tery is in good condition.
If you are not using a maintenance-free battery,the battery fluid level should be checked every50 hours of operation or 3 months. The batterysolution level must be kept between the MAXand the MIN level lines at all times. If the leveldrops below the MIN level line, add DISTILLEDWATER ONLY until the battery solution levelreaches the MAX level line.
WARNING
Battery acid is poisonous and corrosive,and can cause severe injury.
Avoid contact with eyes, skin, clothing,and painted surfaces. If battery acidcomes in contact with any of these, flushimmediately with large amounts of water.If acid contacts the eyes or skin, getimmediate medical attention.
WARNING
If you are not careful when checking orservicing the battery, you can cause ashort circuit, which could result in anexplosion, fire, or circuit damage.
Disconnect the negative (black) cablewhen checking or servicing the battery.Be careful not to allow a metal tool orother metal object to touch the battery’spositive terminal and the motor at thesame time.
WARNING
Battery posts, terminals, and relatedaccessories contain lead and lead com-pounds that may be hazardous.
Wash hands after handling.
NOTICE
If you add diluted sulphuric acid to thebattery after it has been initially serviced,you will damage the battery.
NEVER add diluted sulphuric acid to thebattery after it has been initially serviced.Follow the battery manufacturer’sinstructions for specific maintenanceprocedures.
