View Full Version : WTB: Tandem trailer conversion part near Florida

02-18-2012, 08:05 AM
Has anyone converted their Prostar 205 1992 or like single axle trailer to a tandem. It looks like the frame is the same and the guards(fenders) almost built on ? Does someone know if the second axle can just be bolted in along with the fenders? It is an original master craft trailer that I have.
Also looking for spare axle and fenders if this is the case in the Florida area, suggested wreckers/ dismatlers would be helpful. I have a boat coming back to Australia from Florida in the next week, so need to move quickly.

Thanks for anyone who can help.

I doubt you could just "bolt in" a second axle. Spring hangers/shackles would have to be welded in, brake lines would have to be installed plus changing the fenders. Sounds pretty costly. If you don't like your single axle trailer you might be better off looking for a good used tandem and sell yours. Contact some MC dealers ([email protected] on here is a good start) and check e-bay for used trailers.

What don't you like about your single axle? Your boat doesn't really need a tandem, and singles are easier to roll around by hand.

Thanks for the quick response, the welding and changing of spring hangers is ok, i can get that done - but a very good point. It more about the fitting of the fenders and if the axle and extra wheel will actually fit on the main trailer frame. In fact i would really like to know if they are in fact the same trailer frame as the tandem? I don't have my boat yet so I can't measure it. As for "why" the tandem, I drive about 1 1/2 hours and a couple of back roads to get to the ski spot so it will be better on the road.

I am in the process of doing the same thing for my 94' 205. That boat with full fuel and camping gear pushes the limit for the stock trailer, and tandem axles are a safety factor on the rode. I have a parts trailer and intend to rob the other axle, move and remount both, and possibly modify the springs for ride quality. Would love to find a set of stock tandem fenders without buying new$$$. [email protected] has one used tandem fender. Fabricating mounts and steps for an aftermarket steel fender may be the rode ahead. In this case the trailer has to be refinished, so color match is not at problem. I will be posting progress on a similar thread this page. Good luck and keep posting.

Thanks for the response sounds like a good approach, would appreciate anyone who knows boat wreckers in the Florida area that have trailer parts?

Keep in mind that the original axle will have to be moved so that the two axles use the original axle location as a centerline to distribute weight properly. Certainly a project that can be done, but I would want to be sure of who is doing it for you. It would be cheaper and faster to purchase a tandem trailer, especially from a dealer where you could trade your trailer in. And the dealer should have all the necessary paperwork on the trailer to assist in it's long ride down under. as Jerseydave suggested, Jim at Bay Area Watersports would be a great guy to talk to on this. 813-996-2297

His website shows a used tandem for a newer 205 that could work.


Good luck.

I believe I would look for one at dealer to trade with.

For all who posted on this thread, I stayed with the single axle and changed the trailer to have LED lights and a little bit of alimimium checker plate. Fully sand blaster and repainted with new runner boards and carpet. Thanks.

Also I have another boat on the way and need some help with trailer a trailer compliance plate for an original MC single axle. Please respond to the thread below if you think you can help.
