CAUTION
Freeze damage can occur, if operating where temperatures are below 32 degrees F (0 degrees C). Use
Manual Drain System to ensure heat exchanger is completely drained.
NOTE: This procedure is written for the air pump that is attached to the engine. However, any air source can
be used.
1 Remove air pump from engine.
2 Ensure that lever on top of pump is flush with the handle (horizontal).
3 Install air pump on the actuator fitting.
4 Pull lever on air pump up (vertical) to lock pump on actuator fitting.
5 Pump air into the system until both green indicators extend and water drains from both sides of the engine.
6 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. (A)
CAUTION
Manual release valve may not close completely. Ensure valve is completely seated.
