5. Shift outboard to neutral (N) position.
6. For initial start of a new engine or for an engine that ran out of fuel, or was drained of fuel, the
fuel system should be filled as follows:
a. Squeeze the fuel line primer bulb until it feels firm.
b. Turn the ignition key switch to the "ON" position for three seconds. This operates the electric
fuel pump.
c. Turn the ignition key switch back to the "OFF" position, and squeeze the primer bulb again
until it feels firm. Turn the ignition key switch to the "ON" position again for three seconds.
Continue this procedure until the fuel line primer bulb stays firm.
7. Do not advance the neutral fast idle speed feature on the remote control for starting.
8. Turn the ignition key to "START" position. Release the key when engine starts. If engine fails to
start in 10 seconds, return the key to "OFF" position, wait one second and try again.
NOTE: The electronic starting system will automatically prime (choke) the engine and increase idle
speed for starting.
9. Check for a steady stream of water flowing out of the water pump indicator hole.
IMPORTANT: If no water is coming out of the water pump indicator hole, stop engine and check cooling
water intake holes for obstruction. No obstruction may indicate a water pump failure or blockage in the
cooling system. This condition will cause the engine to overheat. Have the outboard checked by your
dealer. Operating the engine while overheated will cause engine damage.
