Scalawag,
I really couldn't give you an honest answer since the only time I was aboard a new 17' proline was at the boat shows. I was pretty impressed. The dry wt of just the hull is a little heavier then mine and is still much heavier then the other brands (around 1500 lbs). I know that the new ones are all glass construction which should be better down the road. If I had the cash, I would buy new. A few years ago I think the 17s went for around 16,000 +/- 1k (boat, motor 90merc and trail). I would upgrade to a 130 hp and you will really fly. My boat with no load and the 87 inline 6 90 hp goes around 30kts and I cruise nicely at 24 kts.
I don't like the new consuls much with the scooped out bottom. Mine is rectangular and I have a lot of stowage underneath.
It is what I think the perfect boat for one or two anglers for the bay, sound or ocean on a decent day.
Hope this helps
