Located on the aft head wall is a monitor which displays the fill level of the holding tank
When the tank is filled, it can be discharged overboard or emptied through the deck pump-out
fitting. Following are instructions on both operations:
Overboard Discharge
1. Open the discharge seacock located under the aft berth subfloor with the disch. I.D. tag. This
seacock must be open prior to discharge to prevent damage to the discharge pump. To
access, take out the center cushion and remove the compartment cover board.
2. Supply power to the pump at the DC panel using the switch labeled Holding Tank Dis-
charge.
3. Engage the pump using the key switch in the tank manager panel on the aft head wall. Turn
the switch to the “manual” position. The discharge pump will run until the tank manager
panel indicates the tank is empty.
4. Close the discharge seacock when the tank is empty.
Deck Pump-out
1. Remove the cap from the deck pump-out fitting located in the starboard walkaround.
2. Connect a vacuum hose from a pump-out station to the deck fitting and run until the tank is
empty. Replace the cap on the deck pump-out fitting.
See “VacuFlush® Head Layout” on page 8–31 for a layout diagram.
Washdown Operation
To operate the washdown, open the seacock with the washdown I.D. tag located in the
forward bilge beneath the sole floor rigging lid. Depress the washdown switch on the
accessory switch panel. This system will now be pressurized at the “raw water” washdown
outlets, located on the port side of the aft cockpit and on the port side of the foredeck. A hose
with a spray nozzle attached may be used intermittently without turning the switch off in the
same fashion as a home yard hose with a nozzle. The washdown pump has an internal
pressurization switch that will maintain water pressure as needed until the switch is turned off
at the switch panel. The pump is located in the forward starboard rigging compartment and
may be accessed via the access panel in the aft storage area under the helm. See
“Livewell/
Washdown System” on page 8–30 for a system diagram.
C A U T I O N
Overboard discharge seacock must be sealed and secured in the “closed” position in accordance
with the laws in your boating area.
