It depends on the tongue weight.  Can you lift the tongue?  If it were me, I would look at the one I had and then go to the Cabela's website and find one that looked like it.  Depending if time or $ was the concern, you could then go on and search for it cheaper.

My jack is still working fine but it's as old as the boat and I just thought I would buy one of the new ones that fliped up when it's hooked to the boat. I think I will try one of the 1500lb Fulton Jacks. I move my boat quite a bit up and down the driveway so I'm going to try the one with the big rolling wheel.

Thanks for the info!
