I priced out the items on these websites:

www.easternmarine.com & www.etrailer.com (free shipping on orders over $150.00)

I also checked on www.trailerpart.com

so do you just buy a solid coupler and cut the other one off and bolt the new one on? im kinda new to this end of it and my brakes are shot

You do bolt in a new coupler. However, I have seen a surge brake converted to EOH that the surge coupler was welded solid.

I just pinned mine with three 5/8" Grade 8 bolts. Simple and strong.

Every trailer could be different; my surge brake coupler was bolted on, I found a solid coupler that uses the same bolt holes so I am just re-bolting on the new coupler.

I had my coupler welded and then painted to match the trailer.

All brake parts, removed old brake lines, completely rewired, all new lights, , new break-away line, new bearings.

I also replaced the controler in the truck, new fuses, relays, connectors, etc. Total was right at $2000.

I'm not looking at the invoice, but I think the service call and labor was around $7-800. It took two guys about 8 hours to complete everything.

I keep it out at my parent's house in the winter and that's where the work was done. I took it out and pulled a few miles with it. Nothing major yet. I really liked the feeling of the brakes. Here in the Cincy area we've had non stop rain. While boating season technically just opened, my marina is on the Ohio River and pretty much under water right now. It'll be a few weeks before I'll be able to boat.

for the guys that have all electric brakes do you unplug connector before backing trailer in water?

i havent. i just make sure not to put trailer in water right away after a long haul.

Are the brake solenoids made for water immersion? I always thought that the reason surge brakes were used on boat trailers is because the electric solenoids were not meant to be totally submerged. I too need to rebuild my trailer brakes, and electric would be MUCH better than surge (and cheaper than EOH). Any info is appreciated.

Ok, after going out and looking at several of the sites above, are all electric brake setups drum? I currently have surge disc brakes and really don't want to step back to drum. With three axles to redo, changing everything is going to get pricey, especially if changing the rotors. As you can tell, I don't know alot about trailer brakes.
