I've found what seems to be a very solid 1978 Yarcraft with a 105hp Chrysler. It has 4 seats but a huge open area between the front and back seats. I'm 230lbs and no give in the floors. I couldn't get any wiggle out of the transom either. Anybody familiar with these? The price is pretty good, $1800. I'm a total newbie so any and all advice is appreciated!
