Thanks Danny and Jim. I registered on the Moyer Marine forum and will post the question there as well.
I doubt I cranked it enough to hydro-lock it. When it cut out the last time, I cranked it twice for maybe five or six seconds each time. Enough to suck fuel through if necessary, but no more. There’s no point in continuing to crank, I figure, and risk running the batteries down. If it won’t start in a few seconds of cranking then something is wrong. But I didn’t know about the hydro-locking potential. I’ll change the oil and pull the plugs and see what it looks like. But even hydro-locking wouldn’t explain why the starter wouldn’t operate when I pushed the starter button the last time and nothing happened. I’m inclined to suspect one or more faulty circuits.
