5. Pump air into the system until both green indicators extend and water drains from both
sides of the engine.

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.
