WARNING SYSTEM–MODELS WITH CARBURETORS
1 The outboard warning system incorporates a warning horn inside the boat. The
warning horn may be located inside the remote control (a) or under the dash
(b) connected to the ignition key switch.
The system is designed for the warning horn to emit either a continuous beep or
intermittent short beeps. This will alert the operator and help identify the following
listed problems.
• The warning horn sounds continuously
The problem is engine overheat. See explanation following.
• The warning horn sounds intermittent short beeps.
The problem is low oil level in the oil injection system. See explanation
following.
2 When the ignition key is initially turned on, the warning horn will sound for a
moment as a test to tell you the system is working. Failure of this test indicates
a problem. Have the outboard checked by your dealer.

WARNING SYSTEM–MODELS WITH CARBURETORS
The Warning Horn Sounds Continuously
Problem – Engine overheat. The warning system is activated when the engine
temperature is too hot.
3 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 (a).
If no water is coming out of the water pump indicator hole (a) 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. See the following note.
If a steady stream of water is coming out of the water pump indicator hole (a) and
the warning horn continues to sound, there still may be insufficient cooling water
or an engine problem. Stop engine and have it checked by your dealer. Operating
the engine while overheated will cause engine damage. See the following note.
Note: If you are in a stranded situation, stopping the engine and allowing it to cool
back down will usually allow some additional low speed (idle) running time before
the engine starts to overheat again.
The overheat problem must be corrected before you can resume normal
operation.

WARNING SYSTEM–MODELS WITH CARBURETORS
The Warning Horn Sounds Intermittent Short Beeps
Possible Problems: 1. Low oil level in the oil injection system.
4 The system is activated when the oil level in the engine mounted oil reservoir
tank drops to the reserve level. You still have an oil reserve remaining for 30
minutes of full speed operation.
Note: The engine mounted oil reservoir along with the remote oil tank will have to
be refilled (refer to Fuel System).
