I have a 2003 Triton TR186 with a 175 Opti sitting on a Marine Master trailer. It appears that I will need a new tongue jack. I presently have a Shelby Industries swivel bolt on jack but there's no model number to be found on it, I'm assuming that a new Shelby with a 1000lb capacity is more than sufficient for this setup?

I'm not sure of the exact tongue wieght but I am able to pick up the tongue, with some difficulty, just ahead of the winch stand, maybe a couple of feet max in front of where the jack is located.

Thanks.
