ECOMMENDATIONS
The standard mixture of water and coolant is a
mixture of 30% environmentally safe, non-toxic
antifreeze and 70% water, which protects to 0°F
(-18°C). This will allow the coolant to expand
properly and maintain normal operating engine
temperature. In colder climates, the coolant level
should be increased to 50/50, which protects to -
34°F (-37°C), for proper coverage. To find engine
coolant requirements for the specific engine on
your yacht, refer to your Engine Owner's
Manual in the Owner's Manual Packet.

The oil change system, located on the inboard port
stringer, center of the port engine, simplifies
changing the oil in the engines, transmissions and
generator. The pump is self-priming and pumps in
either direction. The oil change pump is protected
by the 24 volt OIL CHANGE PUMP breaker on the
DC breaker panel on the port component board in
the engine room.
