Filling
!
CAUTION
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.
!
CAUTION
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.
!
CAUTION
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 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.
