Question:

Will this work with a 1998 Four Winns 180 Horizon? The original jack is the welded on backing plate. Thanks

Hey Mike! You can use the Fulton Boat Trailer Jack w/ Wheel # FTJ120W0301 on your 1998 Four Winns 180 Horizon. However, you will need to measure to see if this matches the current bracket. See the attached photo with measurements. Worst case you can cut off the old one and weld-on the included backing plate. You can also weld on the new one in a different location and leave the old one in place for less work.

What kind of jack did you have before? An old Shelby maybe?

Hi Robin. Thanks for your you for your response. Like most I was trying to find a jack that would use the existing snap ring. I had taken the measurements that you mentioned and I felt that this jack would work. I wanted to run it by you to make sure there was nothing I was missing. I also noted others in this forum who have Four Winns trailers of similar age and it seemed to work for them. So I went ahead and bought it. We’ll see if it works. Thanks, Mike

@RobinH. Hey Robin. The Fulton jack fit perfectly on the existing welded on bracket. As mentioned in your video the new snap ring is more sturdy than the old one so I had to wrestle with it a little bit. I did get it done however and the new jack is great. To answer your question, yes the original jack is a Shelby. It has held up well. The problem was that the plastic grip on the sidewind handle had broken off and I couldn’t find a replacement. So if you have any thoughts on where I could get one I will keep the original jack as a backup. Thanks Mike

@Mike I'm glad to hear it fit! Shelby was a common older jack, replacement parts aren't around anymore since the company has been gone for a while. A lot of people try to match new jacks to the original mount from Shelby but those vary. If it didn't work out I thought maybe we could narrow it down based on the model if you have it. Some we know fitment for, others we do not.

I do have an option for you but we do not have an exact replacement for the Shelby Jack 5764A. Instead, I recommend taking a look at the Fulton Bolt-Thru Swivel Marine Jack part #FXP10W0301. This jack similar to the Shelby uses a bolt through swivel…

Answer 8

What you've got there looks like some type of proprietary mount that we don't offer. We do however have jacks that would work. I'd recommend having the mount removed and using a weld-on jack like the Fulton #FXP100W0301 and the #P9012-00…

What we have heard from our customers is that the Fulton #FTJ120W0301 does fit the mounting plate of the Shelby Jack 5784. This would be your best option for a direct replacement.

Answer 12

The Fulton Magnum jack used the #P9012-00 weld-on bracket which would be compatible with the bracket included with the 1200 lb Fulton Jack, part #FXP100W0301 or the 1500 lb model, part #F1411300301. If your attachment bolt that attaches the jack to…
