The dry dock inspection showed starboard prop turned freely (motors off, trans in neutral) while the port side prop was stiff to turn. The initial thought was alignment, but now I'm questioning the transmission clutches.
Would this indicate a bad clutch pack? I know nothing about the internals of these transmissions, assuming they are a Volvo Penta version of Hurth ZF. Are they same for BB vs SB V8's?
There is 217hrs on the port engine but 229hrs on the starboard, does running one engine more than the other damage the transmission?
Is this a common issue? is there a "simple" typical fix?
Does the whole transmission need to be removed to be serviced? or can it be serviced in place?
thanks in advance for your insights and comments as the wife and I are trying to avoid a large money pit issue.
You could either have a valve problem that is pushing some pressure on the clutches or some warped clutches. Do you feel it change significantly when you actually put that engine in FWD? What happens when you put it in reverse? If the RPM on port drops lower than starboard in reverse, that might be a clue that the fwd clutches are still engaged. Running for a long time like that would be bad and overheat the trans, but since you rarely use rev you probably wouldn't have too much of a concern on that.
When it's in neutral and engine off, is there any noticeable drag on the port side vs the starboard side? That might tell you more if it's a warped plate issue.

Regarding your money pit question.......considering what you have come across already, what do you think at this point ?
