what kind of performance can i expect out of each of these boats set up the same witha 36hp PD. Also never had a mud motor before how are the on gas compared to my mercury 25hp that i was running

You'll get better mileage out of the PD when compared to a 25 merc. As far as the hulls I'd go with either a 1760, 1852, 1860 depending if your hunting any flood timber or fishing out of it quite a bit.

But if you really need a 16 footer, I'll sell ya my 1652.

How much you looking to get for it. and how is it set up

Performance will be close to the same but the 17 footer will carry a large load a little better just because of the extra surface area and I would think the extra foot would help it plane a little easier. The extra foot will also help a little going over waves. It's only 12 inches (that's what she said) so the difference won't be too big but the extra room is always nice.

1860 might as well get what you will want in two years.
