Nice! Is this the 307? GM made a 2.14 gear in the mid 80's you could hunt craigslist or the junkyard for a real mpg score. But then it'd be reeeally slow. Is this a th200, th350, or 4 speed? T5 or NV3500 swap would also score some real mpg points. Good to hear these boats are still on the road
...if its th350, people will probably pay you to take an old 200c off their hands (couple extra mpgs).
