I know a little about these boats, but not much more than the general stuff about the drives, engines, and steering.
I have also heard about hull problems with the deck separating from the hull.
Problem is, I really like how the old boats look, and the one I have in mind is super nice looking, and would like to know a little more about them. The model that has my eye is a 1988 312.
Here's a pic of the boat:
Thanks in advance for any info,
Greg
