FREEZING TEMPERATURE OPERATION

If the possibility of freezing exists, the cooling system
must be protected after the engine is shut off to prevent
freeze damage to the engine. Refer to OUT-OF-
SEASON STORAGE for draining instructions.

OPERATION IN HIGH DEBRIS AREAS

If the boat is to be operated in high debris areas, a sea
strainer should be installed in the water inlet hose to
prevent debris from entering the cooling system. The
strainer used must be of suffi cient size to allow an
adequate supply of water for cooling the engine. A
minimum of 30 gallons per minute (114 liters per minute)
fl ow rate is required.
