Section 5 - Maintenance
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.
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.
2. Fill to the "FULL" line with the specified coolant.
Tube Ref No.
3. Install the fill cap onto the coolant recovery bottle.
