Bilge Pumps - Quicksilver 905WE Owner's Manual

Quicksilver 905WE — System & Component Overview and Operation
overboard through a seacock in the bottom of the hull. The macerator control is located on a separate
panel located on the front face in the starboard battery panel tub. Since direct overboard discharge is
prohibited in many areas, the macerator seacock is normally closed.
To Operate the Macerator:
1. Make sure the macerator seacock is in the open position.
2. Press and hold the macerator switch located on the main battery panel. The macerator switch
is a momentary switch, which means that it needs to be pressed during operation.
3. When the tank is empty, stop pressing the macerator switch.
4. Return the macerator seacock to the closed position.

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 tank either via the macerator in an approved location or 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 interior floor
liner. 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.
