Here are the steps mentioned in that subject:
10.5.1.1 To manually operate your bilge pumps:
Note: The power to the MDP does not need to be energized in
order to manually operate your bilge pumps.
1. Locate the bilge pump switches at the MDP and switch
them to the manual position.
2. Another procedure to be used in extreme circumstanc-
es involves locating the float switch and manually rotating
the float handle on the side of the float switch to simulate
the float switch being underwater. This will energize the
pump and the pump will operate.
10.5.1.2 Maintenance on Bilge Pumps
No maintenance is required other than ensuring that the
float switches are operational and that there is no debris
clogging the pump intakes.
10.5.2 Shower Sump
The shower sump is controlled by a rocker switch on the
vanity face and is automatically operated by a float switch
in the sump. Should the sump pump not operate auto-
matically, the manual switch can be used by the rocker
switch in the vanity
10.5.2.1 Maintenance
Clean strainer in the sump. No maintenance is required
on the pump itself.
10.5.3 Holding Tank
The holding tank must be emptied when it becomes near-
ly full. There are two methods for removing waste from
the holding tank, either by discharging overboard when in
waters where it is legal to do so, or by dockside pump-out
at a waste facility. Check with the Coast Guard and local
authorites before discharging waste overboard.
10.5.3.1 Overboard Discharge Operation
All that is required to discharge the gravity feed holding
tank overboard, is the opening of the overboard dis-
charge valve. The valve is located below the tank inside
the head. See pages 10.9 and 10.11.
Important: U.S. Coast Guard regulations require that boats
have a sanitation system on board to control pollution. Waste

is to be stored in a holding tank or other device so it can be
properly disposed of at a shore facility. Discharging this waste
overboard in U.S. lakes, rivers, bays, and sounds and within 3
miles of shore in international waters is prohibited. Check with
the Coast Guard regarding regulations in your area.

Failure to close the overboard discharge valve when
not in use could cause the holding tank to fill and
possibly flood the boat.

Waste in the holding tank can form methane gas.
Use suitable precautions when any maintenance is
done to the sanitary system.
10.5.3.2 Dockside Waste Removal
To remove waste from the holding tank at a dockside
waste facility, insert the hose from the pump-out facility
into the waste access on the coaming (Fig. 10.4) of your
boat and follow instructions at the facility. Instructions
from one facility to another may vary.
Fig. 10.4
10.5.3.3 Maintenance
Maintenance on the holding tanks is best described as
ensuring no methane gas is leaked and to keep odors
down to a minimum. Any deodorizer may be used as
long as it contains no alcohols or strong chemicals. Steer
clear of drain opening type chemicals or strong bleaching
type agents.
