Can Electric Over Hydraulic Actuators be Submerged Under Water on a Boat Trailer

Question:

Hi, I have a tandem boat trailer with surge disc brakes on the rear axle. Some ramps I use are shallow and as a result, the only place on the trailer I would consider installing an electric over hydraulic controller, can be partially submerged. The controller would constantly be exposed to weather. I only boat in freshwater. Are there any concerns with the submersion?

Expert Reply:

Electric over hydraulic actuators are not meant to be submerged but your best option for protection against water is the HydraStar Vented Marine Electric Over Hydraulic Actuator # HS381-8067. It looks like there is space forward of the winch post on your boat trailer so that is a good place to mount it.

One thing that will help to keep less of the trailer submerged is a longer ball mount such as # 80232 which is 16 inches from the center of the hitch pin hole to the center of the ball hole.
