Re: overpropped vs underpropped
Max rpm should be in the engine manual. You raise a very good point. My TAMD31 has about a half dozen variants, signified by a following letter. All but mine have max rpm at 3800, but mine is only 3000. I had one engine shop hear the 31 and assumed the higher rating and went down a rabbit hole trying to resolve an issue.

In the harsh marine environment, something is always in need of repair. Margaritas fix everything.
