It is time to repower my 1991 Sea Sport. The Chevy/Volvo 305 has almost 1400hrs on it and has been failing the last few seasonal compression tests. Last year it was due, this year its past due. It will be replaced with a 350 Merc-cruiser partial, I'll keep the risers/manifolds, heat exchanger, alternator, other items. The block, carb, maybe starter, electrical, will be new. This "new one" is a remanufactuered from Merc, with full warranty.
I'm pleased I was able to milk the hell out of the original motor, she was always reliable, but burned gas like crazy, it's time!
It will be exciting to see what the top speed is and how much fuel it burns compared to the old motor, not so exciting about how much it will cost.
If you have any storys good or bad about your repower experience post em' I'd love to here about it.
