After Use: Flushing Procedure
To prolong engine life it is very important to flush engine of salt water after use and prior to
storage. Failure to carry out flushing will significantly reduce the life of engine components and
may invalidate the warranty.
In addition it is advised to thoroughly wash with fresh water around the jet pump area to remove all
salt deposits after use.
CAUTION.
flooding exists if water remains on after engine is switched off. NEVER run engine
longer than 2 minutes. Drive line seal has no cooling when boat is out of water.
1 Clean jet pump by spraying fresh water into its inlet and outlet.
2 Connect a fresh water hose fitted with the female connector to the flushing attachment
coupling fitted to the tender.
3 Start engine and immediately open the water tap.
4 Run the engine for about 20 seconds, between 4000 and 5000 rpm.
5 Ensure water flows out of jet pump whilst flushing. Otherwise, contact your authorized
Williams Dealer.
6 Turn off tap.

7 Allow the engine to run on for no longer than 10 seconds to allow water to exit from the
cooling system, then turn off the engine. Remove hose connector from flushing attachment.
