I have owned several boats with surge brakes, I currently have a 29' powerquest with them. Whats this talk about e.o.h? what is this and how does it work. I didn't think they used electric actuators in boat trailers??

Electric over hydraulic. Uses the trailers existing hydraulic brake system but replaces the surge coupler with a solid coupler and uses a brake controller you install in your truck (or if you have a factory one). Takes out the bang/slam of the surge.

As stated above. An electric pump (EOH) is mounted on the tongue. A braking signal is sent from the truck cab controller to the EOH pump, which in turns supplies hyd press to your brakes.

It also means no more brakes smoking or catching on fire when going down long/steep grades like you find in West Virginia or Virginia, for us midwest/east coast folks. Been there, done that once on I-77 south ... well, at least the brakes smoking, part. Luckily, no fire.

wow, might check into this. My surge brakes work just fine, but does the truck wiring harness need to be changed to get the signal from the power booster. can you lock the trailer brakes with this system while sitting on the ramp??

Most trucks are wired for electric brakes. Some require the relays and fuses to be plugged in. Depends on yr and make of ttruck. Still need the controller inside and to be plugged into teh wiring harness under dash, unless a new truck that has it built in. Do you have the larger round 7 pin plug at the bumper?
Yes, you can lock the trailer brakes at any time using the manual override lever. But just pushing on the brake pedal is more than enough. I assume you aren't meaning to lock the brakes up and then get out of truck?? With EOH, ANY time you push on the brake pedal, your trailer brakes are braking. Even if sitting still.
If you ever had your front wheels skidding while backing down the ramp, you won't with EOH. So many more benefits of EOH over surge.

Much better system. However a lot more money. Also requires a small battery to power the system if the trailer is disengaged from the tow vehicle.

EOH is hands down the best system out there. However, I have had great luck with standard electric brakes. I have used them in a fresh water marine environment for a long time with no issues. The braking action is superb, and the cost to convert is about 25% of a EOH setup.

i have a 99 f250 superduty 7.3 diesel and do use the big round pin. Yes i mean lock the brakes on the trailer and winch up the boat. My e brake wil not hold the boat, but if i can lock the trailer too that would be great

cool..did some on line research, not that expensive. looking at a titan..brakerite. 1500psi actuator. Can anyone recomend any certain brand. Can i lock the trailer brakes on the ramp and get out of the truck for unloading/loading?? With the trucks e brake applied of course!
