DO NOT use pump to remove gasoline, oil or other flammable liquids.
Doing so could result in fire, explosion, and serious personal injury.

Always use the fuse amperage rating specified for your pump model.
Failure to do so could result in serious personal injury or fire hazards.
Heavy Duty Bilge Pump

Installation Instructions
Attwood marine hardware, navigational lighting, bilge pumps, and other
marine accessories are specified more than any other brand by America’s
best-known boat manufacturers as original equipment. Look to Attwood for
quality replacement parts and marine accessories.

FEATURES
Attwood Heavy Duty Bilge Pumps are the newest development in high output
pumps. All models have a removable housing for simple installation and easy
cleaning. They connect to 12-volt D.C. systems only. There are two ways to
configure your Heavy Duty Bilge Pump – Automatic Operation or Manual
Operation. The bilge pump system can be converted to fully-automatic
operation by installing the Attwood Automatic Float Switch, Part No. 4201
or 4202.
Attwood bilge pumps are designed to exhaust standing WATER ONLY.
They are not intended to prevent rapid accumulation of on-board water
due to rough weather, severe storms, hull damage, and/or other unsafe
navigational conditions.
Do not allow materials containing acetic acid (vinegar smell) such as
silicone rubber sealant to contact the plastic parts of the pump. They
may react with the plastic, causing cracks and pump failure.
Notice:
Discharge of oil prohibited. The Federal Water Pollution Control Act
prohibits the discharge of oil or oily waste into the contiguous zone.
Violators are subject to a penalty of $5,000.
REQUIRED FOR INSTALLATION
•
Drill and suitable drill bits

AUTOMATIC OPERATION
All boats over 20' (6.1 m) in length which have sleeping accommodations
(excluding fold-out cockpit seats) require automatic bilge pump systems. For
fully-automatic operation, follow the AUTOMATIC FLOAT SWITCH INSTALLATION and AUTOMATIC OPERATION WIRING instructions.

The following materials are needed if no pump mounting pad is in place:
Recommendations are based on amount of gallons exhausted per hour
(GPH). GPH measurements are typical of production pumps tested using
smooth-bore hoses, at 0' head. “Head” refers to the vertical distance between
the pump nozzle and the water discharge location. GPH is reduced as head is
increased.
The chart below shows gallons and liters per hour ratings for 0' head and 3'
(91.4 cm) head. GPH/LPH may also vary depending on power source, hose
type, and other variables.

If automatic operation is desired:
• 1/2" (1.27 cm) thick marine plywood block large enough to mount pump
(and automatic float switch, if used)
• Hand-held roller
• Fiberglass—18 oz. (.5kg) mat or woven roving
• Polyester resin and catalyst

The pumps can run dry for limited periods of time; however, doing so could
cause pump failure.
WARNING:
To prevent personal injury, always disconnect the power source when
installing or servicing any electrical product. Remove vessel from water
when using any 110/120 or 220 Volt AC power tools.

1/2" (Minimum) Thick Mounting Pad
1. Choose a bilge pump mounting location in the lowest accessible part of the
bilge. In this location, pump will remove the last 1" (2.54 cm) of standing
water. Also, pump should be as close to the thru-hull connector as
possible, for short discharge hose length.
1. Select a location on the pump mounting pad forward of the bilge pump.
NOTE: It is important to locate the switch forward of the pump to minimize
the possibility of running the pump when there is not enough standing
water, causing the pump to draw air and not turn off.
2. To install mounting pad on fiberglass hull:
Sand gelcoat or paint off the mounting surface to create an area that is 3"
(7.6cm) wider than the mounting pad on each side.
2. Attach shim to mounting pad with a layer of polyester resin.
Completely cover the mounting pad with fiberglass. Saturate the fiberglass
with resin, and press the fiberglass edges down against the hull to adhere
the pad in place. Roll out the fiberglass to remove any uneven surfaces, air
bubbles, or excess resin.
To install mounting pad on aluminum hull:
If your boat is not equipped with a bilge pump mounting pad we recommend that you consult your boat dealer or repair facility for instructions
regarding fabrication and installation of a suitable mounting pad.
PUMP MOUNTING INSTRUCTIONS
3. After resin has dried, center automatic float switch on top of shim.
If you have an Attwood switch without a cover, thread two #8 screws
through attachment holes on switch. Fasten securely into mounting pad.
If you have an Attwood switch with a cover, thread three #8 screws through
cover, then switch. Fasten securely to mounting pad.
HOSE CONNECTION INSTRUCTIONS
1. If no thru-hull connector exists:
Install connector well above the water line (just under the rub rail is best) on
the driver side, where water discharge can be easily monitored. Drill a hole
through the hull to clear the connector threads.
Apply marine sealant around inside of nut flange (do not allow sealant to
contact pump housing). Fully insert thru-hull connector, and screw nut
flange down firmly. Do not over tighten.
Figure 2
LOCK
2. Run hose from pump nozzle up to thru-hull connector, through the most
direct and unobstructed path possible.
3. Before connecting hoses, cut any extra length from hose that causes
downward dips or kinks in discharge line (dips can trap water and airlock
the pump). Be sure the hose tension on the pump outlet is minimized to
reduce stress on the pump components.
4. Place hose clamps onto hose ends. Connect ends to pump nozzle and
thru-hull connector, ensuring that hose ends fit tightly over barbs.
5. Secure both connections with hose clamps.

1. Determine which direction you want pump outlet fitting to point after
installation. Mark pump base and mounting pad in desired position. If
Automatic Float Switch is to be installed, allow enough room on pad for
shim and switch.
2. Remove pump base from motor housing by depressing lock button and
twisting clockwise.
3. Align base with pad at marks, and fasten with four #8 screws.
4. Attach pump to base by aligning four retaining tabs and twisting counterclockwise until the lock button snaps into place.

Make all wire connections above the highest possible water level, using
marine grade wire connectors only. Waterproof all connections with suitable
materials. NOTE: Failure to make waterproof connections and fuse pump
properly will void the product warranty.
1. Splice suitable lengths of brown and black 16-gauge wire to existing pump
wiring, enough to reach ON/OFF/AUTO switch, automatic float switch, and
battery.

of the positive (+) battery terminal. Connect remaining lead from fuse
holder to positive (+) terminal of the three-way switch.
3. Splice the remaining positive lead (brown) from the automatic float switch
into the positive lead (brown) from the pump.
4. Connect the spliced leads to the ”Manual” terminal of the three-way switch.

Important:
Although the switch is submersible, the lead wires must terminate in a
waterproof connection. Mount wires above the highest possible water mark
to prevent electrolysis damage to the boat.
