If you can pull a wheel, the axle should be 1- 1/4 outer and 1- 3/4" dia,
inner for a 6 to 7,000# axle. The springs would have at least 6 leaves
(about 1/4" thick x 1 3/4 to 2" wide). A 3,500# axle would have a 1-1/16"
outer and a 1-3/8" inner with a 4 leaf spring.

I will be looking at a boat trailer for sale by a tow company that has
been in their yard since it was towed by order of police.
It is a tandem, 31 feet long and that's it.
Here is question: The id plate has been removed (was stolen?) and on
it was the VIN and weight info.
The tow company has gotten new pink slip but they don't know the
weight ratings.
How can I tell if it is capable of carrying an 8,500 lb boat? What
should I look for, bigger wheels? Bigger springs? The frame? Size
and number of rollers?
Or am I taking a chance? (I can see putting my boat on it and the
damn thing collapsing, lol)
Thanks for any help
Eddie
