This actually looks like a pretty good deal, over in your area:
2004 Seacraft SC 20 Classic Boat For Sale
But it's a bit light on HP, in my opinion. I was on one about two weeks ago and it hauled along nicely.
My guiding rule for motor boats is that the hull needs to be sound, but IT'S ALL ABOUT THE MOTOR. So an older (sound) hull with new engine would be fine with me.
