Morepower, if you can get it at a good price, then go for it.

The front part where your winch is, usually adjust to a point.

You can also, if the price is right, shorten the bunks, I take it that it has bunks, to fit your pontoon.

The part that gets you is in the rear that the engine will hit if you come up on it to far, plus the added hitch weight you would have, so I would move the winch part back as far as possible and go from there.
