Re: What brand of boat is this?
I'm going to toss out a Godfrey Hurricane deck boat, but ONLY because I can't recall anything else with that style.
The motor is easy...1973-1976 V4 OMC 85,115 or 135. It you want T&T, make sure the unit is fully functional. They've become rare and $400+ if you can find them.
EDIT: The Viking suggestion is excellent!
