    Feels like a stretch?

    I've been working for a couple years on a 1966 or so SabreCraft, with an identical vintage Mercruiser package including the GM inline 6. It's been nothing but a PITA, but I'm too dumb to quit. I got the boat in early '22, tuned it up, got it running, put maybe 10 hours on the engine (during...
