Trailer rollers

[Redfred1]

I have a '89 Escort trailer that has the bunks; and am guessing the PO installed keel rollers on the crossmembers. The rollers are the same ones that go up by the winch for a stop.
The Admiral usually drives the boat on the trailer; but her aim is off sometimes. Was thinking about replacing the rollers with the 12" ones. My question is how much pressure should be on the rollers and still work with the bunks?

rollers are guides jut to keep the bow from bonking on the cross-members as you launch/retrieve. the bunks do the heavy work.

Center rollers / twin bunks is the classic trailer design. The old "Trailer Boater Guide Book" printed back in the 1960's specified that the rollers should support the weight of the boat. The bunks should only be snugged up tight enough so the boat won't rock on the highway.

By all means, go to 12 inchers. If you use the Stoltz self centering rollers you'll never have to drive the boat on again, plus launching will be effortless.

I upgraded my brand new bunk trailer that way last year and boy what an improvement. I always use 12" center rollers, but those Stoltzs were BETTER than sliced bread.

I use the self centering Stoltz rollers also. I always buy the stainless steel shafts to go with them.
