Oil Consumption

Postby fpc310 » Fri Sep 13, 2019 7:27 pm

I realize that no oil consumption is normal. My Stbd 318 consumed about 1.5 quarts after 12 hours of running. I know the previous owner only ran this boat twice a year at most and that was at 2000 rpm or less. What’s the worst case / best case for this motor? I plan to check compression soon, but I’m looking for suggestions on how to get a few more years out of this motor.

Oil's cheap. Long as plugs aren't fouling, why not just keep the level up?

You might have worn out intake valve seals, that can be changed without removing the heads. It's a messy job.
