Trailer Reverse Question
Recently had the trailer serviced for a stuck caliper and all seems fine now. Prior to this work we could not back up at all without putting the trailer brake key in. We went out to the lake this weekend and it backed into the water fine, thus we chalked the problem up to the seized caliper. However, when we got home and went to put it in the driveway, we had to put the key in to back up. The boat was on a slight incline forward the way the road is if that makes a difference. The vehicle is a 2004 Jeep with the trailer install done right from the factory, thus I am sure it is wired correctly to allow it to back up this type of trailer. Any other thoughts on where to look?

My first boat, the 02 Mobius, had the same key. I don't think that it has the reverse selenoid like my 06 XLV does. I always had to use the reverse key when I put the 02 in the driveway. My 06 doesn't have the key, just the wiring to release it when the backup lights come on.

Sounds normal to me. I have an 06 LSV, and I do not have the reverse solenoid wired. I rarely ever use the key to back my trailer. My drive way has a ever so slight grade as I start backing in then it tapers down hill. I've only used the key once that I can remember getting into my driveway. It usually backs up with no problem.
I will say that when you turn around to back up you need to pull forward kind of quickly to make sure the cylinder is completely extended before you back the boat up. This will help keep it from braking.
Some trailers breaking systems are more free and sensitive than others.
Obviously, if you back up a steep grade you will need the key or the reverse solenoid wired to your reverse light circuit.

My 07 was driving me crazy with not being able to back up but only sometimes... I have the back up solenoid. I chased ground wire trouble first but finally ended up being a bad solenoid. I changed it out and this is now a pretty sweet system.

I know that all double axle trailers '07 & up use the UFP A-60 actuator / disc brakes with backup solenoid which eliminates the key. IF you have the A-60 without solenoid you can easily convert it by adding disc brakes, the solenoid, 5-pin connector and running the extra wire. I've done this already on two other trailers and doing another in a week or two.

My 2001 trailer has the same issue. I have the backup solenoid on it, and I have it wired properly, but the brakes still apply when I back up. I am guessing the solenoid has gone bad. Where would one buy a replacement? Dealer? Boatmate?

If it's the UFP A-60 actuator you can get it direct from UFP in San Marcos, CA.
