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.
