C. Dockside Waste Pump Out
On most V Series models waste pump out capability
is available. Waste can be removed from the holding
tank by taking the boat to a dockside waste pumping
station. Most marina fueling facilities provide such
services.
The waste holding tank should be emptied when
the waste level indicator reads full. The waste level
indicator is located on the 12VDC cabin panel.
See Figure J16. DO NOT ALLOW THE WASTE
TANK TO BECOME OVERFILLED.
To pump out the holding tank:
1. Be sure the head has some water in the bowl.
2. Connect the dockside pump out connection to the
WASTE plate located on the deck. See Figure
J17.

NOTICE
Usual ly the dockside pump out connection will
screw into the waste deck plate or has a
rubber sleeve that inserts into the plate and
must be held in position during the pump out
operation. If the hose is not air tight or connect-
ed prop erly, waste could spurt out or leak
around the deck fitting and into the boat.
3. Have the pumping station operator activate the
pumping equipment. The waste will be drawn from
the holding tank and into the pumping station's
disposal tank.

SYSTEM MAINTE NANCE
The decomposition of waste produces a
colorless, odorless gas, methane, that is lighter
than air, combusti ble, and ex treme ly le thal.
Always provide sufficient ventila tion when
effecting repairs to the waste sys tem and allow
no odor from the waste system to go
unresolved.
