The Yamaha 15 hp motor uses a 2 stroke fuel mix as previously described. To start the motor proceed as follows;

Check fuel level in tank and open air vent.

Lower motor into drive position and lock in place

Insert the red kill switch slide under spring loaded button on tiller arm

Pump priming bulb until pressure is felt to ensure fuel to carburetor.

Check motor is in neutral on the gear shift control.

If motor is cold pull out choke control and set throttle to start position.

Take up the slack on the pull cord, make sure no one is behind your arm then pull firmly on the cord. Repeat until the motor has started then release the cord gently. Push the choke in before the motor stalls and turn the throttle back to idle as soon as the engine is warm.

Make sure water is flowing from the tell tale on the motor side. If it is not it could be a blockage on the tell tale outlet or it may indicate a loss of cooling water flow around the entire engine. Running with out cooling water will cause the motor to seize.

Check that all lines are onboard and secured to prevent fouling the propeller. To engage forward gear shift the gear lever ahead and back for reverse, twist the throttle gently to accelerate.
