Air filters replaced twice. Airflow pathway clear. Not it.

Greetings,
Mr. HW. So, NOT the cockroach eh? Hmmm...Too much fuel is being injected and/or not enough air is getting to the cylinder(s) for complete combustion.

Alrighty then...
It wasn't the port engines fault at all!
The starboard transmission was slipping! The Starboard engine reved up to WOT but the prop didn't. The boss looked at the stbd shaft and said it ought to be turning alot faster for that RPM.
The Port engine was overloaded trying to pull the whole boat up to speed because the stbd was slacking off, hense the black smoke.

Though, why wouldn't the port engine "come up to cruise" RPMs as per your OP?
I would have thought it would in this case?

The stbd engine was not pushing much at all. Had the owner tried to power the boat from the starboard engine alone, the fault would have been obvious. But he always pushed up both throttles together.

But given that the port engine would have behaved normally and got to normal RPM for that throttle position, and the boat would have turned to starboard, hence indicating an weakness issue with the starboard engine? No?
