Bilge Pump Maintenance
Inspect bilge pump intakes frequently and
keep them free of dirt or material which may
impede the flow of water through pump.
NOTICE
Gray Water Sump
Your boat is equipped with a gray water/condensate
sump which can be accessed through the hatch in
the floor of the cabin in front of the galley (see
Figure 3.3.1) . Gray water from the galley, shower,
condensate from the cabin air conditioner and freezer
plates all drain into the sump.
The sump contains its own automatic pump to
discharge water when there is enough water in the
sump to raise the float switch and start the pump.
Maintenance
Periodically remove the clear cover and check the
pump and float switch for proper working order.
Clean out any obstructions which may inhibit the
pump from performing correctly.
After using shower run a gallon of clean
water through shower drain to flush out soap
residue.
NOTICE
In the event that water has risen in the bilge
sufficiently to activate the high water float switch, the
emergency high water bilge pump will automatically
begin to pump water out of the bilge, an audible
alarm (loud buzzer) will sound at the helm and the
“HIGH WATER INDICATOR” light on the helm
switch panel will be ON.
Take immediate action:
• Switch all bilge pumps ON.
• Use your radio to broadcast a PAN-PAN
distress call.
Emergency High Water Bilge Pump
The aft pump and high water pump can be accessed
through the equipment hatch in the aft cockpit floor.
The forward pump can be accessed through a hatch
in the floor of the cabin.
To clean the pump strainer, depress the lock tabs
on both sides of the pump and lift the pump motor
(Figure 3.1.1).
If water does not come out of the discharge hose:
1. Remove the motor module to see if the
impeller rotates with the power on.
2. Remove any debris that may have
accumulated in the impeller section or
strainer base.
3. Check hose and connection on hull side
for debris and proper connections.
Float Switch
Frequently inspect the area under or around the float
switches to ensure they are free from debris and
gummy bilge oil.
To clean:
• Soak in heavy duty bilge cleaner for 10
minutes, agitating several times.
• Check for unrestricted operation of the float.
• Repeat the cleaning procedure if necessary.
Fuel and Oil Spillage
Regulations prohibit discharging fuel or oily waste
in navigable waters. Discharge is defined as any
action which causes a film, sheen or discoloration
on the water surface, or causes a sludge or emulsion
beneath the water surface. A common violation is
bilge discharge.
Use rags or sponges to soak up fuel or oily waste,
then dispose of them properly ashore. If there is a
large quantity of fuel or oil in the bilge, contact a
knowledgeable marine service to remove it. Never
pump contaminated bilge discharge overboard.
