I'm curious as to what boat trailer jacks you guys have good luck with.

My trailer jack is frozen up, this is the third one in four years. I've been using the standard Fulton tongue jack, the small ones that run about $40 or so.

I never get salt water in mine, and this last one I babied, turned it upside down and squirted it with WD-40 and everything, just like I'd heard to do... any suggestions?

I've had other ones last longer, but only when I kept my boat indoors.
