Best way to lock out surge coupler?

Default Best way to lock out surge coupler?

I have a surge coupler on my boat trailer. Occasionally, and at the worst time, the reverse lockout solenoid acts up or my wiring needs to be repaired and I am unable to back up as the brakes will lock up. ON my last trailer that had a surge coupler there was a pin that allowed the coupler to be physically held in place to prevent it from sliding and engaging the brakes.

My buddy thinks I could buy a big C-clamp and clamp the inner tongue to prevent it from sliding in. I said no way a C-clamp will hold against a ~12,000# boat. My plan was to simply drill a hole in both parts of the sliding mechanism and dropping a Grade 8 bolt in the hole on that rare occasion I need to physically lock out. Other than upgrading to electric over hydraulic... any other ideas out there before I get my drill out?

4x4 and zip ties work in a pinch.

I've done both the c-clamp and the drilled hole/bolt. The clamp worked OK, but it had to be really cranked-on there. The thru-bolt worked a lot better.

Where would the hole for the bolt need to be drilled? My recent trailer purchase has surge brakes and there was a pin that I was was wondering what it's purpose was. Not sure where it would go hence the question.

Thank you...

On the coupler area that angles down you could weld an angle brkt or something to it and then insert a long bolt or rod to lock it out. I had a boat trailer a long time ago that had a setup like I described and it worked well.

Does this hole not go all the way through? looks like the whole where you would insert the pin you just need to find the pin

4x4 and electrical tape. Did this for years only while backing up. Worked great until I finally fixed the solenoid. I still keep said 4x4 and electrical tape in my truck for when it goes out again.

4x4 and a clamp is all I needed to backup my 10k boat without any issues or problems. Don't see why it wouldn't work for your 12k boat. Below is a link to the clamp that I used. I've since switched to EOH and don't have this issue any longer.
