I'd appreciate any help in understanding this device. It's in the exhaust
path of a Yanmar
3qm30 on a C&C38. I'm assuming it's a float to prevent seawater from being forced back up to the cylinders (if you're pooped?).
I'd like to know if it's a good thing or a potential source of failure. I just had the exhaust
pipe part at the top of the loop out of the manifold and the seawater output backed up the pipe and was flooding the boat. So it could have gotten into the cylinders. I'm thinking this thing kept the water
from getting out - altho' without exhaust to push it, it might not have anyway.
Thanks in advance.
