my dad got this boat from my great uncle about 10 years ago, still in PERFECT condition, but when you turn it over it wont start, have had some people look at it, heard it was a powerpack, nuetral switch, all kinds of stuff. im 22years old now and bought the boat from the old man. i wanna get it going on the water. ANY info regarding the engine (or boat) would be great. thanks for looking! the boat is a 1967 thunderbird with a cathedral hull.
