(173PO) 12 VOLT TROLLING MOTOR ENGLISH 7.5” X 10.3” 11/02/2011
Boat rigging and motor installation
An over-current protection device (circuit breaker or fuse) must be used with this motor. The
C oast
Guard requires that each ungrounded current-carrying conductor must be protected by a manually
reset, trip-free circuit breaker or fuse. The type (voltage and current rating) of the fuse or circuit breaker
must be sized accordingly to the trolling motor used. The following breaker sizes are recommended
guidelines:
Maximum thrust voltage recommended circuit breaker rating
30# to 45#
12V 50A @ 12VDC
50# to 55# 12V 60A @ 12VDC
The appropriate wire size needed to connect your trolling motor to the trolling motor batteries varies
depending on the length of the cable needed and voltage of the motor. For further information and
requirements, consult with your local ABYC (American Boat and Yacht Council, for USA) and Coast Guard.
Propeller replacement
1. Disconnect the motor cables from the
battery before changing the propeller
and servicing.
2. Hold the propeller and loosen the
propeller nut with pliers or a wrench.
3. Remove the propeller nut and washer.
If the drive pin is sheared or broken, hold
the propeller shaft steady with a flat
screwdriver pressed into the slot on the
end of the propeller shaft.
4. Turn the old propeller to horizontal
position and pull it straight off. If the drive pin falls out, push it back in.
5. Before installing the new propeller, make sure the drive pin is aligned 90 degrees with the small guiding
studs.
6. Align the new propeller with the drive pin and press into place.
7. Re-install propeller washer and nut.
8. Tighten the nut 1/4 turn past snug. Do not over-tighten the nut.
Maintenance
•
After each use, rinse with fresh water and then dry out with a cloth dampened with a water based
silicone spray.
• After each use, the propeller must be cleaned of weeds, fishing line or any objects. Fishing line and other
objects can get behind the propeller, wear away the seals and allow water to enter the motor. Regularly
check the propeller/motor seal for wear and tear.
• Before each use, ensure the propeller nut is securely tightened.
• To prevent accidental damage during traveling, stowing and/or storage, disconnect the motor cables from
the battery whenever the motor is out of the water. For long term storage, lightly coat all metal parts with
a water based silicone spray. Do not store in freezing temperatures below 32
O F / 0 O C.
• For maximum performance, restore battery to full charge before each use.
• Keep battery terminals clean with fine sandpaper or emery cloth.
• The propeller is designed to provide weed free operation with very high efficiency. To maintain this
performance, the leading edge of the blades must be kept smooth. If they are rough or nicked from use,
restore by sanding with fine sandpaper.
Troubleshooting:
1. Motor fails to run or lacks power:
a. Check motor for obstructions. The motor may have gone into current limit. To reset: return
handle to off position, remove obstruction and resume operation.
b. Check battery connections for correct polarity.
c. Ensure terminals are clean and corrosion free. Use fine sand paper or emery cloth to clean
the terminals.
d. Check battery water level. Add water if needed.
