Hello Bad Santa
I have a new to me boat and have only ran the engine for testing purposes. I read your comment about over cranking the engine 3gm30f and getting water into the cylinders. I am curious about the phenomenem as I would not know how to diagnose this issue. You said you had done it a couple of times, so you know how to not do this as well as how to resolve the issue once it happened. Any advice and direction will be greatly appreciated. My engine has a 180 degree water injector (inverted "U"). Will this be susceptible and does the muffler type, have any affect?
Thank You for any attention you give to these questions.
