After the input from TF members and speaking with others I decided to go with the OEM turbo from my mechanic. It certainly isn't the cheapest solution, but the savings I'd realize from other options is <1K and I feel better about an OEM vs. reman.
You need to solve the salt water intrusion issue or you will ruin another turbo. Probably needs the exhaust elbow (s) reconfigured. To my knowledge Mainship was known for not having enough height in their exhaust risers. (Yanmar wants 13” of height from waterline to the spill over point in the riser minimum) At minimum I would add a rubber exhaust flap to the exhaust outlet.

My Yanmar turbo was roughly the same price as yours. Yanmar sources their turbos through several OEM’s. A good turbo shop will cross reference and save you 5 or 6 hundred and you will get the correct turbo. Best to do this or stay with Yanmar. Cheap turbos scare me.
