Replacement Swivel Jack for a Champion Boat Trailer

Question

Question:

Hello- My boat trailer has a bracket that was welded onto the frame of the trailer by the mfg that built the trailer now out of business. It is a fulton magnum jack, but I cannot seem to locate similar models where I can plugandplay as the bolt patterns do not match up. I keep being told I can keep the mount, and just swap out the jack components, but Im not finding the right one to do this with. Can you help?

Fulton jack # FTJ120W0301 is going to be your best bet. The Magnum series jacks are no longer made and were an entry level jack so you might not be able to find an exact match to fit the mount. However, this Fulton jack comes with a mount should you need it and a professional welder could weld it onto your trailer for a nominal fee.

If your old jack uses the bolt style mounting bracket # P9012-00, then you could use jack # FXP15W. The Magnum series jacks used two different style mounting brackets, the bolt style and the c-clip style.
