Hey Brandon, the horizontal distance between the mounting holes of the etrailer jack part # e35YV that you referenced is 3-1/2 inches. The horizontal mounting holes are separated by 1 inch. Are you trying to match this jack to an existing mount?

I'm looking for a replacement jack for my boat trailer. The current jack is a Fulton F2 1600lb. The mounting bracket with threaded holes is welded onto the trailer. The hole spacing is 4 1/2" horizontally by 3 1/2" vertically, on-center. I prefer to utilize the existing mounting bracket. I imagine the vertical and horizontal mounting orientation on the replacement jack could simply be rotated 90 degrees to fit the 3 1/2" mounting holes? My ideal replacement jack will have the following: - Drill adapter - Swivel-up storage - >=2k lift capacity - Flat foot plate Please let me know if the E35YV is a viable solution and if you have any other recommendations. The Fulton F2 failed due to the composite gearbox housing disintegrating, so I'm not interested in another Fulton jack.

@Brandon I wish we had something that used the same mounting brackets as the Fulton F2 but it was a unique jack and mount and the parent company for Fulton is no longer around so there isn't a suitable replacement available that would use the same mount. The # E35YV will work but you would need to either mount the jack to either side of the current mount or cut it off and reattach it.
