ENGINE OVERHEAT
Check for a steady stream flowing out of the water pump indicator hole. If no
water is coming out of the water pump indicator hole or flow is intermittent, stop
engine and check cooling water intake holes for obstruction. If no obstruction is
found, this may indicate 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.

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.
ENGINE OVERSPEED LIMITER
If engine speed exceeds 6400 RPM, the overspeed limiter will be activated.
The engine timing will be momentarily retarded to prevent operation above this
limit.
Some causes of engine overspeed are as follows:
•
Propeller ventilation
•
A propeller which has an incorrect pitch or diameter
•
Propeller hub slippage
•
Outboard mounted too high on the transom
•
Tilting the outboard out beyond a vertical position
•
Cavitation of the propeller due to rough water or obstruction in the boat
hull
Trim Tab Adjustment
Propeller steering torque will cause the boat to pull in one direction. Steering
torque results from the outboard not being tilted so the propeller shaft is parallel
to the water surface. The trim tab can help compensate for this steering torque
in many cases and can be adjusted within limits to reduce any unequal steering
effort.
Operate your boat at normal cruising speed with the outboard set at the desired
operating angle position. Turn your boat left and right and note the direction the
boat turns more easily.
