Hi Billy,

The F500277 is for a Fulton trailer jack that is no longer in production. The 4 3/8" x 3 3/8" bracket measurements are typically from an older style weld on trailer jack, we used to have a version that fit those dimensions, but it has since been discontinued.

Our best course of action is to cut off the old bracket and weld on a new one for another trailer jack. Since your boat is roughly 2,000 to 2,175lbs depending on the model, your tongue weight is 10-15% of that. So, the Ultimate Trailer Jack - Sidewind with 27 1/2" Lift part # UJ44FR would be more than enough to lift your boat trailer. It can either be bolted on or welded on, has a 1500lb lift strength, and is zinc plated steel to resist corrosion.

What's your favorite place to take your boat out fishing?
