1900 running hours suggestds that overhaul time is due soon, maybe
very soon....

Funny, my Perkins 4 cyl diesel has over 2500 hours on it and runs
perfectly. It was made back in 1965 (no, I don't use it much).

Right, I forgot - it's in my tractor. Seems an engine changes when
it's in a boat. Or perhaps it's the lack of maintenance.

Any well maintained diesel fed clean air & fuel, run under proper
load, should last pretty much forever. 2000 hours is nothing.
