Recommended Electric Brake Assemblies for Dual Axle Boat Trailer

Question:

Im looking to do away with old surge brakes on my dual axle boat trailer and install electric. Can not find markings on axles themselves but they measure about 1 3/4inch x 3inch rectangle and are style. Wheels are 14, 5 lug at 4.50. Tag on trailer states GVWR 7480 lbs as well as for GAWR. Also states carrying capacity is 5800 lbs. Axles have 4 hole back plates in place already where drum brakes currently attach. Which items should I be looking to purchase to swap these out? Thanks.

For your conversion to electric brakes I recommend the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA which should be compatible with your current hub/drums. These assemblies need adjustment only at install and then will self-adjust as needed.

I recommend using the # 10-2-1 wiring along with the Deka Heat Shrink Butt Connector - 12-10 Gauge - Nylon Insulation - Yellow - Qty 5 # DW05745-5 to seal your wiring connections. Then I recommend the 7-Way Molded Trailer Plug with Junction Box # HS381-9000 to make your connections with ring terminal # 44-5310A. You will want to use a sealant on the box like # LT37467. I still recommend removing the trailer wiring plug from your towing vehicle when launching your boat because water and electricity don't mix well. You can reconnect a few seconds after exiting the water.
