CORRECT POSITION
Bait & Livewell Pump Installation & Operation
MOUNTING (Suggested installation & operation only. Your installation may vary)
Mount scoop-type thru-hull [high speed pick-up] to hull. Do not drive screws through hull! Below water
level thru-hull fittings must have a seacock shut-off valve. Mount ¾” NPT-M pump inlet port directly to
seacock. For extended inlet ports cut to desired length to fit.
PLUMBING
Use smooth I.D. discharge tubing or hose. Tubing & hose should be rated for below water line use.
Always use double clamps for connections below the water line. Tubing should enter tank at top to
avoid tank draining while pump is off. See illustration for recommended installation.
Avoid airlock & maximize performance: Avoid any sagging or loops in the tubing. Tubing must go up
from pump to tank. Use full-flow style valves only. Valve is used to regulate flow to tank while at rest and
while under way (2 different settings).

ELECTRICAL
Use 16GA wire for all circuits. If installation is over 20 feet, use 14GA wire. Brown pump wire must be connected to positive
power. Use waterproof connectors and splices. Attach all wires to UL Marine approved duty switch rated at or above 10 amps.
Wire connections should be made above water level at the highest possible position. Seal wire connections to prevent corrosion
and electrolysis.
WARNING
Always use fuse with amps rating specified on pump label. Failure to do so may result in
serious personal injury or fire hazards.
OPERATION
Never operate equipment if gasoline fumes are present. Always test pump before leaving dock. Open sea cock before running
pump, do not run pump dry. Tank fill time should be tested at rest and under way. Pump will fill tank faster while boat is running at
higher speeds. General tank fill times are between 7 minutes [warmer water] and 10 minutes [colder water]. Measure tank fill time from
empty while at rest and adjust valve position for desired time. Measure tank fill time at normal cruising speed and adjust valve to
desired time. Refer to tank size chart for optimal pump size. Note position for later reference. Always remember to adjust valve when
at rest or under way. Flow should be circular and slightly upward so debris clears from bottom of tank. Flow should not be too fast that
fish get tired.
WARNING
Do not disassemble base from pump body. Warranty will be voided upon disassembly. SHURflo is not responsible for problems
due to disassembly of base from pump body. Do not pump oil, diesel fuel, gasoline or other flammable liquids with this pump.
Always disconnect power before servicing pump. Always use fuse size specified in specification.
Seacock MUST be closed before removing cartridge from pump housing.
MAITENANCE AND CLEANING
Impeller and Motor Cartridge:
First and most important, close seacock valve. Remove motor
cartridge by removing locking screw and then unscrewing the
blue-collar nut. Remove motor cartridge. Clean out debris and press
Spacer
Remove screw and spacer
prior to replacing cartridge
Blue Motor Cartridge Collar Nut
unscrews ccw for easy impeller
cleaning and cartridge change.
motor cartridge firmly into housing, then hand-tighten blue collar nut
to housing. Make sure to align the finger holes on blue collar nut to
allow room for locking screw. Align spacer and locking screw.
Pump Body
Assemble screw and spacer into existing hole. CAUTION: MAKE
SURE NOT TO OVER TIGHTEN SCREW, SNUG IS FINE. Always
check for leaks/cracks and all connections regularly. Repair or
replace as needed. Keep valve closed when system is not in use.
When not using livewell, remove or drain all water from the system.
When removing boat from the water, open seacock valve. When
boat is in water and livewell is not in use, close seacock valve.
