Filling

Alcohol or Methanol based antifreeze or plain water, are not recommended for use in the
coolant section of the Closed Cooling System at any time.
Overheating from insufficient cooling water will cause engine and drive system damage.
Ensure that there is sufficient water always available at water inlet holes during operation.
Air trapped in the closed cooling section of an engine cooling system can cause the
engine to overheat resulting in engine damage. To minimize the possibility of trapping air
when initially filling the closed cooling system, position 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.
