Quicksilver 905WE — System & Component Overview and Operation
Macerator Switch Location
3. When the tank is empty, stop pressing the macerator switch.
4. Return the macerator seacock to the closed position.
Dockside Pumpout
The dockside pumpout deck plate is located on the starboard side of the deck, under the LPG storage
lid, and is marked with the ISO symbol WASTE. The dockside facility will have the proper connections /
fittings to pump the holding tank out.
Maintenance
Maintenance of the waste system will require you to check the fittings and hoses to make sure that
there are no leaks. If the system does require maintenance, or if you have any questions about the
servicing of your black water system (i.e. cleaning materials, safe deodorants to use for the
system) ,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 Waste System:
1. Empty the holding tank either via the macerator in an approved location or the dockside
pumpout.
2. Pump water through the system (via the toilet) to remove any residue waste.
3. Empty the holding tank again, removing all liquids.
4. Pour an environmentally safe antifreeze (Propylene Glycol based) in the toilet and pump
throughout the system.
Refer to the toilet manufacturer's requirements for additional winterization procedures.

4. Grey Water System (optional)

In certain locations, local laws prohibit water from sinks and showers (excluding transom showers) to
drain overboard. Check with local officials on whether or not a grey water system is required where
you boat. The grey water system consists of an 100 liter tank, plumbing connections from the galley
sink drain, head sink drain, shower drain, a macerator, and a pump out fitting.
The dockside pumpout deck plate does not have a chain
connecting the cap to the deck plate. Use caution not to
drop the deck plate cap into the water.
