NOTE: It is not necessary to use the neutral fast idle speed feature on the remote control to increase
engine speed for starting and warm up. The electronic starting system will automatically increase idle
speed for starting and will reduce it as the engine warms up. The engine does not require you to actuate
the primer (choke) for starting. The electronic starting system will automatically prime the engine.
6. 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 "ON" position, wait 30 seconds and try again.
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. These condition will cause the engine to overheat. Have the outboard checked by your
dealer. Operating the engine while overheated will cause engine damage.
7. Check for a steady stream of water flowing out of the water pump indicator hole.
