Quicksilver 875SD — System & Component Overview and Operation
Black Water System
This boat is equipped with an overboard discharge seacock.
Some countries levy severe penalties for discharging raw
sewage and solid waste in waters where it is prohibited. Be
aware of local environmental laws, and respect codes of
good practice. Demonstrating that the macerator is disabled
by locking the system and/or removing the seacock handle
may avoid a fine.
holding tank. To see how much fluid is in the holding tank, press the momentary switch towards Tank
1.
Macerator
The macerator gives the boat operator the means of discharging the holding tank directly overboard
through a seacock in the bottom of the hull. The macerator control is located in the main battery
panel in the starboard battery panel tub labelled "Waste pump 1". 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.
