Heat Exchanger and Exhaust Cooling System Flushing
Flushing the heat exchanger and exhaust cooling system with fresh water is essential
to neutralize corroding effects of salt or other chemical products present in water.
Flushing should be performed when the watercraft is not expected to be used further
the same day or when the watercraft is stowed for any extended time.
Proceed as follows:
1. Clean ride plate up and bottom, and heat exchange with a water hose.
2. Clean jet pump by spraying water in its inlet and outlet.
3. Connect a garden hose to heat exchanger/exhaust flushing connector, do not
open the water tap and do not start engine yet.
4. To flush the exhaust cooling system, start the engine then immediately open
water tap.
5. Run the engine about 30 seconds at a fast idle between 3000 - 4000 RPM.
6. Disconnect the garden hose first, and keep engine running another 10 seconds.
7. Stop the engine.
CAUTIONS:
1. Never flush a hot engine.
2. Always start the engine before opening the water tap.
3. Open water tap immediately after engine is started to prevent overheating.
4. Never run engine without supplying water to the exhaust cooling system when
watercraft is out of water.
5. Never run engine longer than 1 minute. Drive line seal has no cooling when
watercraft is out of water.
6. Close the water tap, then stop the engine.
7. Always close the water tap before stopping the engine.
