Pump air into the system until both green indicators extend and water drains from both
sides of the engine.
Most water will drain from the engine in 3-4 minutes, however, some will remain trapped
in the heat exchanger. In order to prevent freeze damage, leave system pressurized
while transporting boat or during other maintenance items to allow the remaining water
to drain.
IMPORTANT: Before launching boat, pull up on manual release valve. Verify that
green indicators are no longer extended.
CAUTION
Manual release valve may not close completely. Ensure valve is completely seated.
MANUAL DRAIN SYSTEM
NOTE: If air actuated drain system fails, use the blue drain plugs to drain engine.
NOTE: It may be necessary to lift, bend or lower hoses to allow water to drain completely
when hoses are disconnected.
1.
Remove blue drain plugs from front and rear of cool fuel cell and from the seawater
pump.
