Maintenance
Maintenance of the grey water system will require you to check the fittings and hoses to make sure
that there are no leaks. If the system does require maintenance, contact your local dealer.
Quicksilver® recommends that you pump out the system before long periods of non-use. If you are
storing the boat during the winter, we recommend you winterize the system.
To Winterize the Grey Water System:
1. Empty the grey water holding tank via the dockside pumpout.
2. Pump water through the system to remove any residue materials.
3. Empty the grey water holding tank again, removing all liquids.
4. Pour an environmentally safe antifreeze (Propylene Glycol based) in each sink and allow to
drain or pump to the holding tank.

5. Bilge Pumps

Your vessel is equipped with two bilge pumps, with one located in the aft section of the boat, and the
second one located in the forward part of the boat. Access to the aft bilge pump is via the motorwell
access plate, while access to the forward bilge pump is through a hatch located in the starboard
forward cockpit floor. Both bilge pumps are rated for 500 GPH, and are activated automatically by a
built in mercury free float switch when the water in the bilge reaches a predetermined level. You can
also manually operate the bilge pump at the console by pressing the bilge pump switch.
Inspect the bilge pump intakes and keep them free of dirt or material which may impede the flow of
water through the pump. To clean the pump strainer, depress the lock tabs on both sides of the pump
and lift the pump motor.
If water does not come out of the discharge hose:
1. Remove the motor module to see if the impeller rotates with the power on.
2. Remove any debris that may have accumulated in the nozzle section or strainer base.
3. Check hose and connection on hull side for debris and proper connections.
