How to Install an Electric Boat Winch

Replacing your manual trailer winch with an electric winch is a great way to save your strength and load your boat faster and easier. You can either permanently install the electric boat winch or mount it temporarily. The following instructions apply specifically to ProMark Offroad boat winches but may also apply to similar style winches by other manufacturers.

Permanent Electric Boat Winch Mounting

  1. Select a mounting site on the bed of a truck, trailer, or other suitable location. Make sure the mounting location is able to withstand the pulling force of the winch. Steel reinforcement plates or additional bracing may be required, depending on the desired mounting location.
  2. Align the base of the winch with the desired location and mark for drilling the three mounting holes required to attach the winch to the mounting site. Then drill these three mounting holes on the vehicle, trailer, or mounting plate. (See Figure A.)
  3. Use three hardened steel bolts at least 3/8″ in diameter, three lock washers, and three nuts to securely attach the winch to the mounting location. (See Figure A.)
  4. Run the electrical wiring to the power source as directed by the manufacturer. Test the winch operation before attempting to load a boat using the winch.

  3. Attach the winch with its plate to the vehicle’s hitch ball by inserting the hitch ball through the teardrop-shaped hole in the adapter plate. (See Figure B.)
  4. Connect the electrical wiring to the vehicle’s power source, following the instructions provided by the manufacturer. Test the winch operation before attempting to load your boat.
