I have a Fulton side wind jack. Easy to get parts, my jack broke the upper bevel gear (unknown cause). Etrailer has a video on how to take the jack apart and replace parts that are not working properly. I use blocks of wood that act as a spacer, so I don't have the wind the jack so far. I thought about an electric jack, but saltwater does not play well the electric, as sometimes the ramp's lack of steepness necessitates putting the trailer far into the water. Perhaps the only issue I have is that water accumulates in the rectangle plate at the bottom of the jack. I might drill a hole to allow it to drain. Oh and check the grease at the top end where the bevel gears are located.
