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 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. Engine MUST be running before water is connected. Risk of engine
flooding exists if water remains on after engine is switched off.
1 Clean jet pump by spraying water into its inlet and outlet.
2 Connect a water hose to the flushing attachment located next to the jet pump on port side.
Do not open water tap.
3 Start engine and immediately open the water tap.
4 Run engine for 20 seconds at fast idle, between 4000 and 5000rpm.
5 Ensure water flows out of jet pump whilst flushing. Otherwise, contact your authorized
Williams Dealer.
6 Close the water tap, then stop the engine.
7 Apply a coating of XPS lube to exposed pump parts.

Routine Maintenance

To ensure long service life and to maintain the tender in a safe and reliable condition
please follow these routine maintenance instructions. Williams cannot accept any
responsibility for damage or injury resulting from incorrect maintenance or improper
adjustment carried out by the owner.
1 Wash tender regularly with fresh water to remove salt deposits.
2 Check engine oil level. When topping up, do not use synthetic oil; follow engine
manufacturer's recommendations. Engine must be at running temperature when
checking oil level.
3 Check coolant level.
4 Flush open loop cooling system.
5 Apply a good quality marine grease containing Teflon (e.g. Quicksilver 101) to all control
cables both under the helm and at the pump.
6 Check bilges for water ingress, oil or fuel contamination and clean if necessary.
7 Lightly grease the extending running light pole base using white grease or similar.
8 Check condition of all anodes.
9 Loss of tube pressure over 24 hours is not unusual. Temperature and atmospheric pressure
will affect tube pressures. Check pressures regularly.
10 For boats used in tropical environments, the frequency of the routine maintenance should
be increased accordingly.
