Author Topic:   New rollers for trailer

I would like to replace the rubber rollers w/some Stolz (sp?) ones during some winter down time, also paint the brackets, etc. Any suggestions on easiest way to do it (boat needs to remain on trailer)? incl. alignment, how much weight on rollers vs bunks (4 rollers w/bunks), etc.

Have had success shaping a 3' long 4x4 to the keel (cradle) and using two bottle jacks to lift off trailer enough to work on the bunks and rollers --- the 4x4 is laid across the keel and after lifting used two small jack stands to support it from each side while I worked --- this will only lift sections of the hull not the whole thing ---

Here is a pretty good source for what you need [url] index[/url]

Rollers take just about all the weight and the bunks should just lend it lateral support --

Hope this is helpful -- good luck Tom

For Stoltz rollers, I have yet to beat Shoreway Marine's price. Either buy from them, or get one of their catalogs and take it to West Marine for their price matching.
(Never go in a West store without a Shoreway catalog in your back pocket!)

Also consider using the SS roller shafts and cotter pin detail, described elsewhere on the Forum. Tom's Champion people sell these.

Finally, you can lift the hull off the rollers using your trailer tongue jack. If you want to lift the transom off, drop the jack all the way down. This will raise the stern. Support the transom at this height, then raise the jack back up. The transom will be a couple of inches off the trailer! You can completely lift a boat off a trailer this way, and even slide the trailer out from underneath, if you're creative with your blocking. I saw it done on my 25 Outrage once. Worked like a charm.
Begin by first rolling the transom about a foot off the trailer, so you can block the weight and pull the trailer out forward. It's even easier if you have overhead beams to attach cables to the lifting eyes.

Finally, this trailer jack method can also be used to raise or lower an engine on the transom, or to add a transom jack, if you have an overhead beam to hang the engine from as you do it. Use chain or steel cable and cable clamps, etc, and your engine brand lifting eye. No rope, which will stretch.

Thanks for the suggestions...what I am most concerned about is horizontal and vertical alignment...I guess I could use a string for horizontal but how 'bout vertical, i.e., how much weight/pressure on each roller...?
