GENERAL MAINTENANCE
GENERAL MAINTENANCE
After every use, the entire motor should be rinsed with freshwater, then wiped down with a cloth dampened with an aqueous-based
silicone spray.
• Do not spray water into the ventilation openings in the head of the motor.
• The composite shaft requires periodic cleaning and lubrication for proper retraction and deployment. A coating of an aqueous- based
silicone spray will improve operation.
• The propeller must be inspected and cleaned of weeds and fishing line after every use. Fishing line and weeds can get behind the
prop, damage the seals and allow water to enter the motor.
• Verify the prop nut/anode is secure each time the motor is used.
• To prevent accidental damage during transportation or storage, disconnect the battery whenever the motor is o of the water.
• For prolonged storage, lightly coat all metal parts with an aqueous based silicone spray.
• For maximum battery life, recharge the battery(s) as soon as possible after use. For maximum motor performance, restore battery to
full charge prior to use.
• Keep battery terminals clean with fine sandpaper or emery cloth (flooded lead acid only).
• The propeller is designed to provide optimum operation with very high eciency. To maintain this top performance, the leading edge
of the blades must be kept smooth. If they are rough or nicked from use, restore to smooth by sanding with fine sandpaper.
• Stow the motor after each use to allow water to drain from the steering housing. Water that sits in the steering housing when the motor
is not in use may cause damage.
1. Motor fails to run or lacks power:
• Check battery connections for proper polarity.
• Make sure terminals are clean and corrosion free. Use fine sandpaper or emery cloth to clean terminals.
• Check battery water level. Add water if needed.
2. Motor loses power after a short running time:
• Check battery charge. If low, restore to full charge.
3. You experience prop vibration during normal operation:
• Remove and rotate the prop 180°. See removal instructions in the Propeller Replacement Section.
4. Experiencing interference with your fish finder:
• You may, in some applications, experience interference in your depth finder display. We recommend that you use a separate deep
cycle marine battery for your trolling motor and that you power the depth finder from the starting/cranking battery. If problems still
persist, call our service department at 1-800-227-6433.
