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
Operation. The bilge pump system can be converted to fully-automatic
operation by installing the Attwood Automatic Float Switch, Part No. 4201
or 4202.
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

MANUAL OPERATION
For manual operation of your bilge pump system, disregard the references to
Automatic Float Switch installation and operation.
Check the chart below to select the proper pump, fuse size, and thru-hull
connector for your boat application:
Pump
Part Pump Amp Outlet Hose Thru-Hull
Number Model Volts Fuse Inside Dia. Connector
4030, 4031 HD1700 12VDC 10 1-1/8" (29mm) 3874
4060, 4061 HD2000 12VDC 12 1-1/8" (29mm) 3874
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.

DO NOT
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.
Attwood bilge pumps are designed to exhaust standing
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
• Screwdriver and four #8 stainless steel pan head screws
• Attwood thru-hull connector of appropriate size (if not already installed
• Marine sealant
• 1-1/8" (29mm) inside diameter smooth-bore hose of suitable length
• Two appropriate hose clamps
• 16-gauge wire, brown
• 16-gauge wire, black
• Attwood 2-Way Dash-Mounted Control Switch (Part No. 7615), 3-Way
• Fuse holder and appropriate fuse (see chart)
• Two insulated terminal connectors for 16-gauge wire
• Suitable materials to waterproof electrical connections
If automatic operation is desired:
• Attwood Automatic Float Switch, Part No. 4201 (with cover) or
• Shim for float switch mounting
• Three additional #8 round-head stainless steel attaching screws
The following materials are needed if no pump mounting pad is in place:
• 1/2" (1.27 cm) thick marine plywood block large enough to mount pump
• Hand-held roller
• Fiberglass—18 oz. (.5kg) mat or woven roving
• Polyester resin and catalyst
use pump to remove gasoline, oil or other flammable liquids.

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. 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.
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.
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.

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.

NOTE: It is important to locate the switch
the possibility of running the pump when there is not enough standing
water, causing the pump to draw air and not turn off.
2. Attach shim to mounting pad with a layer of polyester resin.
3. After resin has dried, center automatic float switch on top of shim.
If you have an Attwood switch
through attachment holes on switch. Fasten securely into mounting pad.
If you have an Attwood switch
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.
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. 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.
2. Using insulated terminal connectors:
Connect positive lead (brown) to the ON/OFF/AUTO switch.
Connect negative lead (black) to negative (-) battery terminal.
In a location easily accessible for changing fuses, splice fuse holder into
positive lead (brown). The fuse holder must be installed within 72" (183 cm)
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.
