APPLICATION
Suited for many general pumping applications where a
flooded intake condition exists. This pump is NOT
SELF_PRIMING. Typical uses include livewell filling and
circulation, deisel fuel transfer (NOT GASOLINE), and
other applications not requiring a self-priming pump.
INSTALLATION
The pump must be mounted in a dry location – the motor is
not waterproof and must not be submerged. The unit can be
mounted in any desired position. It is best to mount so that
water dripping from loose port connections will not wet the
motor. The pump head may be mounted vertically on a thru-
hull and seacock for applications requiring overboard water
to be pumped aboard. A seacock must be used between the
hull inlet fitting and pump on below-waterline installations.
WARNING
!Explosion hazard. Do not pump
gasoline, solvents, thinners or other
flammable liquids. To do so can cause
an explosion resulting in injury or death.
Explosion hazard. Do not operate with
rivets removed from motor case.
Explosion resulting in personal injury,
death or property damage can occur.
Case openings must be sealed to avoid
explosion and maintain ignition
protected rating.
WARNING
!

ELECTRICAL CONNECTIONS
Connect black wire to negative (-) terminal of battery.
The orange wire should run to a properly sized (see elec-
trical specification) overload protected switch or circuit
breaker, with a wire from switch or breaker to a positive
(+) terminal of battery. Electrical circuit must be indepen-
dent of all other accessories. To prolong motor life, install
pump so normal motor rotation is clockwise. Use proper
wire size as determined by wire table elsewhere on this
sheet.
PLUMBING CONNECTIONS
The intake and outlet ports have internal 3/4” pipe
threads. Brass or plastic pipe fittings may be used to suit
the installation. Plastic fittings that may be subject to
cracking due to vibration should not be used below the
the waterline. PTFE pipe joint tape or compound should
be used if brass fittings are installed in pump. Hose
maybe used with common pipe adaptor installed in the
pump ports.
MAINTENANCE
Check all electrical connections periodically, particularly
in saft water areas. Corrosion can cause loss of perfor-
mance or nonoperation in extreme cases. The motor
should be protected with a corrosion inhibiting spray and
any rust should be removed and the motor repainted.

OPERATION
The pump may be run dry for short periods of time.
Running without liquid allows heat to build up between
seal and shaft, thus shortening seal life. The pump can
run against a closed outlet such as encountered when
using a garden hose type shut-off nozzle. Small particles
of trash and debris will pass through the pump, though
an intake strainer should be fitted K excessive problems
are encountered with pump clogging.
WARNING
!
Explosion hazard. If pump is operated
in an area containing flammable vapors,
wire leads must be joined by insulated
mechanical locking connectors. Loose
or inadequate wire connections can
spark resulting in an explosion. Property
damage, injury or death can occur.
Motor runs hot; about 180°is normal
temperature. Prolonged contact
during operation can cause a burn.

SERVICE INSTRUCTIONS
Disassembly
1. Remove end cover screws, end cover and gasket.
2. Remove pipe plug in top of body and rotate impeller
so the set screw aligns with the plug hole. Insert a
3/32” allen wrench through the plug hole and loosen
impeller setscrew. Remove the impeller.
3. Remove screws securing the body to the motor and
remove the body.
4. From the inside of the body, insert a dowel into the
seal area and press the seal out of the seal bore.
Assembly
1. From the rear of the body, press the seal into the seal
bore with the lip angled toward the pump cavity.
2. Apply a small amount of grease to the shaft in the
area where the seal contacts it. Slide the body on to
the shaft and secure it t othe motor with the two
mounting screws.
3, Align the impeller set screw with the flat on the motor
shaft and slide the impeller onto the shaft until it hits
the rear of the body. Then slide the impeller forward
about 1/16” and secure it with the set screw. Rotate
the impeller to ensure it does not rub on the body. Re-
install the pipe plug in the pump body.
4. Ensure the body and end cover surfaces are clean
where they contact the gasket. Align the end cover
and new gasket with the body and secure it with the
end cover screws.
MAINTENANCE
Check all electrical connections periodically, particularly
in salt water areas. Corrosion can cause loss of perfor-
mance or non-operation in extreme cases. The motor
should be protected with a corrosion inhibiting spray and
any rustshould be removed and the motor repainted.
