re: Inboard Motor on 1983 Imperial Boat
Hi Kay,
There's a lot of problems that could cause the stalling. I think your boat has a Mercruiser engine. Have someone check out the shift cable if it stalls when you are shifting as this can mess up the cut-out switch timing. Worn shift cables don't cause as much trouble out of water and can go unrecognized.
If that doesn't work, then check the fuel water separator. Again, there are so many causes/variables that it is hard to diagnose a stalling issue.
Good luck!
