Question:
I am planning on replacing the surge brake coupler/actuator on my tandem axle boat trailer with the Hydrastar Marine Electric Over Hydraulic kit. My trailer currently has a Tie Down Engineering coupler. Is it possible or recommended to replace the current moving coupler with a new, fixed coupler to go along with the electric actuator?

Expert Reply:
Hey David, so what you can do is lock out the moving components of your actuator by having them welded together or having a bolt ran through both pieces to hold them together.
Or you could have the whole thing removed and install a straight tongue coupler like the Demco part # DM13203-95.

Hey David, how did things go with locking out or replacing the moving coupler on your boat trailer? Your results could really help others deciding between welding their actuator or switching to a straight tongue coupler.
