Question:
I need to replace an old Shelby 5756A jack on a Prestige boat trailer. I have found past inquiries, where you recommended the Fulton Round, Snap-Ring Swivel Marine Jack FTJ120W0301, but it does not appear to be available any longer. Can you please recommend a jack that is currently available as a direct replacement. Again, based on past inquiries, the snap ring pilot hole diameter should be 2.313 Thank you for your assistance.

Hey Andrew, thanks for reaching out. We do have a jack that can be used to replace your Shelby 5756A, but it isn't a direct replacement.
If you want something that will match up with the current snap ring bracket, we have the Round Snap Ring Swivel Jack # TJB-2002S-B. This has a 15-1/2" retracted height, so I'd want to make sure this will work with your trailer. Also it has a footplate instead of a wheel.
If you want something with a wheel, we have the etrailer Boat Trailer Jack # MJ-1200B. This has a 1,200 lb capacity and a caster wheel just like the FTJ120W0301 you mentioned. This doesn't use a snap ring bracket though. It uses a bolt-on bracket so you'll need to make sure there is room on the trailer tongue on either side of the snap ring bracket. Or have the snap ring bracket removed.
What's more important to you - using the current snap ring bracket, or having the caster wheel?

This jack is a solid and easy jack to use and stow when driving. I put an anchor on the tongue so I can hold up the hand crank from dragging.
