My cast iron wet exhaust fell apart from rust. It shows 400 hours over 40 years. The boat has been on the hard for 8 years. I relaunched in September, 2021.
I removed manifold/expansion tank and found lots of black diesel residue in the #3 exhaust port. I found even more hardened diesel residue filling up the exhaust manifold exit port where it enters the failed failed wet exhaust.
I feared moisture had got into #3 but I turned the engine by hand and detected good compression followed by relatively easy turning motion between compression.
I shorted the contacts on the starter solenoid for an instant and the engine turned aggressively.
The next time I shorted the contacts the starter spun as if the bendix did not engage.
I think my expansion tank is solid - though I will test it before reinstalling.
I've cleaned out the hardened diesel residue from the engine exhaust port and the exhaust manifold/expansion tank. I will install a new SS wet exhaust elbow.
But, I have a question and would appreciate your thoughts. Did I break something when I engaged the starter for an instance? Bendix? Starter? engine?
I'll probably pull the starter and take a look, but I don't know how many times I have bumped a starter by shorting the solenoid without any negative consequences, so I wanted your wisdom before I proceed.
Have a great day.
