
Check for fumes in bilge, continue to ventilate if present.

Verify proper fuel selector valve position (dual tanks only).
Starting
Follow the information in your engine manual if it deviates from the following instructions.
Before Starting Engine-

Ventilate all enclosed space, and run blower a minimum of four minutes.

Visually inspect bilge for raw fuel, and smell for vapors.

Visually make sure propeller is clear of obstructions or swimmers.

Make sure engine cooling water intakes are submerged.

Lock helm seats to face straight forward.
For a Cold Engine-

Pump the throttle two or three times to prime (stern drive only).

Advance the throttle approximately 1/4 open (out of gear).

Activate the choke while cranking.

Release the choke as engine smoothes out.
For a Hot Engine-

Leave the throttle closed and choke off.

If engine fails to start in 5 seconds, partially open throttle (out of gear) and try again.

If flooded, keep throttle open for a few minutes and then crank. When
engine starts close throttle smoothly as the engine clears to prevent over
revving.
After your engine starts make sure to observe a few basic rules to ensure that the engine is
functioning properly:

Verify oil pressure and water circulation.

Check the water temperature gauge for the first few minutes to make sure the engine is
warming properly.

Check for leaks especially fuel, shut down and correct if found.

Follow the break- in procedures for your engine.

After engine is warm and after the necessary break- in, drive the boat at
full throttle for a few moments ( if conditions permit) to verify engine is
developing full RPM.
Torque
The twisting force that the engine applies to the prop lists the hull of your boat in the opposite
direction the propeller is turning. For a large engine or light hull this list can be considerable. A
listing hull has more drag on the side that is deeper in the water causing boat to turn in the direction
of the list. The trim tab on your out drive should be adjusted to counteract the torque steer for the
load and speed the boat is most often operated at. Consult your engine manual for specific
