MOUNTING:
Your motor is shipped with two mounting bolts. Use a
hoist capable of handling 350 pounds to safely lift the
engine from the crate on to the boat.
Align the motor to the center of the boat then mark the
mounting holes and drill using a 3/8” drill bit.
Use silicone to seal the bolt holes. Do not over tighten
the bolts and crush the mount or boat transom.
BREAK IN PROCESS: Very Important
All motors should be broken in over a ve-hour period.
During the rst hour do not run full throttle longer than
two minutes. For the next two hours do not run the
motor at full throttle longer than 15 minutes at a time.
Run the nal two hours by varying the throttle position
every 10 minutes.
Model 5000 requires checking the valve adjustment at ten
hours. This is the owner’s responsibility. (See page 18 for
instructions.)
Change the oil at 10 hours.
FUEL AND STORAGE:
Use Stabil or an equivalent brand fuel additive if you are
storing the engine for more than two weeks.
It is important to use a fuel stabilizer whenever the
engine is not being used for more than two weeks.
There is no warranty on fuel systems and subsequent
damage incurred by improper storage. See page 22-23
for proper motor storage.
For carburetted models, do not use a quick disconnect
fuel hose which can restrict fuel delivery. You can use a
marine primer bulb, however, do not excessively pump
the primer bulb as it can damage the carburetor.
If you are using a front (bow) mounted fuel tank, use a
minimum size 5/16” fuel hose.
Use a minimum of 87 Octane fuel for the 23, 25, 35, 37
and 40 EFI models. The 4400 and 5000 models must use
91 or higher, octane fuel.
BATTERY:
Use a Group 24 or larger battery with at least 550
cranking amps.
If the battery is located in the front of the boat, use
4-gauge battery cable. Your motor is equipped with a 9
foot, 4-gauge wire and 120 amp breaker.
