WARNING SYSTEM OPERATION
The warning horn will emit a continuous beep. This will alert the operator and help identify the following listed
situations.
Function
Engine Over Temperature
Low Oil Level
ENGINE OVERHEAT
If the engine overheats, immediately reduce throttle speed to idle. Shift outboard into neutral and check for a steady
stream of water coming 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 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.
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. Operating an
overheated engine 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.
LOW OIL LEVEL
The warning system will be activated if the oil level drops below the low oil level on the dipstick. There is still oil
reserve remaining for 30 minutes of full speed operation. Refer to Fuel & Oil - Filling Oil Injection System.
