WARNING
Read all instructions carefully before installing and using this product.
To prevent personal injury, disconnect the power source when installing
or servicing this product. Always remove the boat from the water before
using 120V AC power tools.
DO NOT use pump to remove gasoline, oil or other flammable liquids.
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 WATER
ONLY. They are not intended to prevent rapid accumulation of
on-board water due to rough weather, hull damage, and/or other
unsafe navigational conditions.
Refer to Specification Chart to be sure you have selected the
proper pump:

HOSE CONNECTION INSTRUCTIONS
IMPORTANT: To prevent airlock, hose must rise continually upward
to the thru-hull connector with no dips or sharp bends. Support hose
if necessary.
1. Orient pump outlet for a direct, unobstructed hose path.
2. Secure all connections with hose clamps.
3. If no thru-hull connector exists, install at 12" min. (25mm) above
water line. Apply marine sealant around thru-hull flanges on
interior and exterior of hull.
PUMP MOUNTING INSTRUCTIONS
1. To access mounting holes, remove base strainer. Hold housing with
one hand, depress locking tab with other. Twist counter-clockwise
and remove pump housing from base. It is not necessary to remove
motor cartridge for installation. (Figure 2)

MATERIALS REQUIRED
• Three #8 stainless fasteners, suitable length for mounting surface
• Cordless drill and 1/8" (3mm) bit
• Hose clamps (Attwood # 9185, 2 per connection)
• Mounting pad: marine plywood, fiberglass cloth and resin
• Manual (# 7615A) or automatic float switch (#4201 or 4202)
• Fuel-resistant, reinforced smooth bore outlet hose
INSTALLATION LOCATION
1. Position pump in the lowest accessible part of the bilge. On
sailboats, location should be centered over keel. (Figure 1)

2. Use base as template to mark 3 mounting holes in mounting pad.
CAUTION: Do not drill through hull. Before drilling be sure mounted
pump will be correctly positioned with pump nozzle pointing toward
thru-hull connector. (Figure 1)
3. Remove base. Drill three 1/8" (3mm) pilot holes at marked locations.
4. Replace base. Attach with #8 stainless steel fasteners.
5. Re-attach pump to base. Insert into base, twist clockwise until tab
snaps in and prevents turning. (Figure 2)
WIRING INSTRUCTIONS
Make all wire connections above the highest water level. Use marine
grade wire connectors only. Waterproof all connections with suitable
materials. (Figure 3)
NOTE: Failure to make waterproof connections and fuse pump properly
will void the product warranty.

MAINTENANCE AND TROUBLESHOOTING
Disconnect power to the pump. Regularly inspect and clean to be
sure that debris is not blocking the strainer or impeller.
If pump runs but does not pump water:
1. Check for airlock. Be sure that outlet hose runs upward to the
thru-hull connector, with no dips. (Figure 1)
2. Remove pump housing from base. Remove debris from chamber
and impeller. Be sure impeller is firmly attached to shaft and is not
cracked or broken. (Figure 2)
If pump does not run:
1. Check fuse. Be sure electrical connections and fuse are waterproof
and haven’t loosened. (Figure 3)

12 or 24 Volt DC
(Power Source)

1. Connect positive lead (brown) to switch. For automatic operation,
use Attwood Automatic Float Switch (#4201 or 4202). Connect
negative lead (black) to ground.
2. Install fuse holder within 72" (183 cm) of the positive (+) battery
terminal. Use standard automotive (SAE J554) glass tube type
electrical fuse.
3. To test system, feed water into the pump. If flow appears low, be
sure wires have been connected properly: Brown-to-positive (switch),
and black-to-negative. Reversed wiring reduces performance and
can cause pump failure.

To replace motor cartridge:
1. Hold pump housing, depress motor cartridge tab and twist cartridge
counter-clockwise to remove (Figure 2).
2. Check motor cartridge fit: See specification chart for replacement
motor cartridge number. Motor must match housing color:
500 Series = RED, 800 = BLUE, 1200 = GRAY.
3. To reinstall cartridge: Coat O-ring with vegetable oil (petroleum-based
oils will cause deterioration).
4. Insert cartridge into housing. Twist clockwise until you hear tab
snap up into slot. (Figure 2)
