Can Electric Brakes be Used on a Boat Trailer

Question:

Can these electric brakes be used on a boat trailer. I was wondering if the water fresh water only would be a problem. Thank you.

Expert Reply:

Traditionally, trailer manufacturers did not use electric brakes on boat trailers because the brake magnet wiring and trailer wiring did not always have the best insulation or water protection.

These days, more and more manufacturers are using electric brakes on boat trailers due to improvements in wiring insulation and heat shrink connectors. If you are going to use electric brakes, I strongly recommend using heat shrink butt connectors, like part # DW05745-10, when splicing the wires together.

I have attached links to all of our electric brake assemblies. The easiest way to choose the correct brake assemblies for your trailer is to find the weight capacity of your axle. If you can tell me the weight capacity of your axle, I would be happy to find a set of brakes that will work for you. I have also attached a shoppers guide on how to add electric brakes to a trailer.

You may also need new hubs/drums. If you previously had hydraulic brakes, then not all hydraulic brake drums are compatible with electric brakes. The axle capacity will again determine which drum will work for you. If you cannot find the axle capacity, please send me the gross vehicle weight rating (GVWR) of your trailer and the inner diameter of the existing drums (10in or 12in).

If your trailer does not have a 7-way trailer connector, then I recommend picking up our 7-way upgrade kit, # ET7WK, and an appropriate length of duplex wire, # 12-2-1, for the brakes.
