Hey Guy as you know I have been looking for a trailer. I am getting a 12' jon boat. In the treasure hunt I have found 2 PWC (wave runner) Trailers for $350. Now I want to go see them  and take the measurments to see if it'll work for the boat. I want to know if anyone has ever done this and if it works. I was thinking if the trailer is about 10' the the boat will hang over a littlre bit like 2' or so. Will this be ok if it is strapped down?

I personally would extend the trailer if i took that option, especially if you plan to hang a motor on it.

Yes it works.

The springs may be a little stiff since a wave runner out weighs a jon boat.  If you don't have a motor on the transom then there is no need to extend the bunks to under the transom. Jet skis are longer than they look.  The trailer may already be 12 ft.
