The F2 Jack comes in bolt-on and weld-on versions. I used the bolt-on version. It comes with two sets of U bolts to attach to the trailer. The size that fit the height of my trailer was too long to fit. My solution was to remove the factory jack and install the F2 over its mount. Doing so required cutting slots for the U bolts to fit through near the corners and cutting off the bolt that held the factory jack in place.
I started by jacking the tongue of the trailer up high and lowering it on to a 6x6 which I used as a jack stand while replacing the jack. Then I used a 3/4" wrench and a hammer to remove the nut that held the factory jack in place. Once it was off I held the new jack up to the factory mount and marked the areas that I would need to cut out to mount over the original weld-on mount. I used an angle grinder to remove material in these four areas until the U bolts fit. Then I cut the bolt that held factory jack out of the center of the factory mount leaving a flat surface to mount the F2 to.
This is a picture of the mount after grinding.
I plan to dismount the jack in the near future and use some galvanizing spray to cover the areas that were exposed.
Before installing I adjusted the height of the F2 Jack. This is done by loosening a large allen bolt and a 3/4 bolt on the back side. In test fitting I found that they default setting did not allow the F2 to lift the trailer high enough to be above the ball on my truck.
This is the jack installed
The F2 Jack makes it much easier to roll the boat around in the garage. My main reason for replacing the factory jack was corrosion that was likely due to salt water exposure.
