Raising wobble roller assembly?

[Sandspinner]

I have a magic tilt trailer with wobble rollers for my 21' CC. If I'm not on a steep ramp it's a bear to push off. I was thinking of raising the front roller assemblies an inch or two if it's possible. Any reason I shouldn't? Thanks

Hi SS, why wouldn't you just tie the boat off to the trailer (With slack of course) Back down and hit the brake. Easy peasy.

The "Flying Launch", even better when you leave someone on board to start her up...

Thanks for input. I'd like to avoid a flying launch. Would be nice to just push her off.

I agree
When I'm at the ramp everybody and their brother wants to tell me to it that way and also to just drive it back up onto the trailer.
I don't do either and have no problems getting on and off the trailer without any tricks or potentially dangerous tactics

I would think you can raise those front assemblies up a bit so long as you don't go too high that it wants to slide backwards when you don't want it to and put to much pressure on the winch, cables, tie down straps and whatever while you are driving down the road.

Sometimes its an issue of not being properly balanced on the trailer and sitting too far forward.
Maybe you can move the front winch mount apparatus back a bit so the boat sits a bit further back and will slide off better?

You have to be careful of the tongue weight, when I first bought my trailer which is a bunk trailer, I complained about the tongue weight being to heavy, the boat was sitting to far forward and the tongue weight was 2k lbs, way over what it was supposed to be, so they moved the boat back 1.5 feet, the tongue weight is now 750lbs.

Moving yours back may help, but watch your tongue weight, too little is just as bad as too much.

Also, I have never seen a boat with rollers come off a trailer real easy except on a steep incline, you may have developed flat spots on the rollers, the weight of a 21' boat has to be around 3k + or - a few lbs, rollers or not, it's an effort if there is no incline.
If your trailer splits and gives a grater incline, can't see what the problem is.

I went from a roller trailer to bunk beds a couple of years back. Amazing how different launching and retrieving is. But I stupidly adjusted the "tilt" of how the boat sits and scraped the bottom of the outdrive skeg and prop when I forgot to raise it. Adjusting the height of the bunk beds by either bow or stern also changed where the bow eye lines up to the winch tower. I finally decided to just watch the tides more carefully on the few days I use the boat (I normally kayak) as top of the tide is murder launching at my town's boat ramp and at low tide I have to make sure I can catch the line as the boat floats right off and retrieving is just as easy.

Thanks guys. I have the tongue weight dialed in so not much wiggle room to bring the boat forward or back much. I might try adding some keel rollers as well but will keep the brunt of the weight distributed on the wobble rollers.

Perhaps its time to replace some of those rollers. I purchased a bunch from Eastern Marine at $6.30 a piece (Yates) and after changing them out I now have to tye the bow cleat to the winch post just to remove the winch hook. Boat flies off the trailer (20'er). Not saying you don't properly maintain your trailer but it made a world of difference for me.

It is an older trailer and certainly couldn't hurt to replace them. Thanks for the input.
