NOTICE
Using propylene glycol antifreeze in the closed cooling system can damage the cooling
system or the engine. Fill the closed cooling system with an ethylene glycol antifreeze
solution suitable to the lowest temperature to which the engine will be exposed.
NOTICE
Without sufficient cooling water, the engine, the water pump, and other components will
overheat and suffer damage. Provide a sufficient supply of water to the water inlets during
operation.
NOTICE
Air trapped in the closed cooling system can cause the engine to overheat, resulting in
engine damage. Minimize the possibility of trapping air when initially filling the closed
cooling system by positioning the boat so that the front of the engine is higher than the
rear of the engine.
NOTE: Add coolant only when engine is at normal operating temperature.
1. Remove the fill cap from the coolant recovery bottle and inspect the gasket. Replace
the gasket if necessary.
IMPORTANT: This closed cooling system flows coolant at a high rate. Higher idle speeds
increase dispersion of trapped air into the system making it more difficult to purge trapped
air. Operate at idle during filling and air purging when specified.
2. Fill to the full mark with the specified coolant.
