ENGINE OVERHEAT
If the engine overheats, immediately reduce throttle speed to idle.
Shift the outboard into neutral and check for a steady stream of
water coming out of the water pump indicator hole.
9647
If no water is coming out of the water pump indicator hole, or flow
is intermittent; stop the engine and check the cooling water intake
holes for obstruction. If no obstruction is found, there may be a
blockage in the cooling system or a water pump problem. Have the
outboard checked by your dealer. Operating the engine while
overheated will cause engine damage.
If a steady flow of water is coming out of the water pump indicator
hole and the engine continues to overheat, consult your dealer.
Operating an overheated engine will cause engine damage.
NOTE: Should overheating occur and you are stranded, stop the
engine and allow it to cool down. This will usually allow some
additional low speed (idle) running time before the engine starts to
overheat again.
