Salt Water Boating
NOTICE
If you use your boat in salt water or other unusual water
conditions, fresh water flush your engine and cooling system with
freshwater.
Nautique offers an optional fresh water flush kit. The relief valve in
this kit prevents excessive water pressure to your engine. Excess
water pressure can damage the engine. This is the only system we
recommend if you use your boat in salt water or unusual water
conditions. Flushing the system by running the boat in fresh water
is another good way to flush the engine, but it must be done
immediately.
Fresh Water Flushing Kit-
Optional
The optional freshwater flushing kit allows you to flush the water
system after your boat is operated in salt water, brackish water or
unusual water conditions.
We recommend using this system if you use your boat in salt water
or unusual water conditions. Flushing the system by running the
boat in fresh water is another good way to flush the engine, but it
must be done immediately.
DO NOT connect the flushing kit to a water source which exceeds
normal municipality water pressure.
Proper Use of Freshwater Flushing Kit
1. Open the ball valve located between the system’s deck fitting
and main engine cooling water supply hose.
2. Make sure that the ball valve located in the main cooling system
supply hose is open. This valve is located near the hull inlet
fitting.
3. Open the cap of the system deck fitting and properly connect a
water supply hose, making sure the connection is secure.
4. Turn on the hose and start the engine.
