Re: Which Winch???
I've always heard Warn winches are #1. I've had a few different brands and I liked my 12,000 Lb. Warn the best of all. (Electric)
I never used a winch underwater, but I had some problems with an off-brand winch that somehow got enough moisture inside the motor to burn it up.
I think if I knew I'd be using my winch underwater, I'd buy a gear drive and add the PTO box and shaft to the truck.
hint:when you get a winch, invest in a good fairlead and a snatchblock as well.
Don't own a Ford, but I've worked on quite a few.
