Yes, very possible, but the volvos take a long time to push the boat up to plane. Long enough for the owner to compensate with the hydraulic steering. In his mind, the port eng would only get to 2600 rpm with heavy smoke and the stbd ran right up to 3800+ with no smoke. He came to the conclusion right there that the port eng was the problem. The mechanics came aboard to troubleshoot why the port engine would not rev up and was smoking.

Didn't they ever try to throttle it up out of gear?

That was fun! Well - entertaining anyways... at least for those of us NOT paying the mechanics! Tuck that away in the mental file!

No rudder position indicator? It would be an early indicator of a problem with asymetric power.

I hope he got a big refund for them replacing everything but the block on the port engine!

Some will knock off labor if they have made a big mistake...obviously not expensive parts that you didn't need but they probably won't eat those.

Have seen them eat the cost of some bulk fluids like winterizing antifreeze when the tech obviously wasted way too much.

I think it really depends....this misdiagnosis was pretty egregious for replacing parts, filters, etc...but was one of those that if the young guys were working it...I can see the incorrect path they followed. Yet it is a path too many shops follow.

Happened to me and the result was a total repower. Both engines removed and rebuilt, new transmissions, etc. etc. for my cost of 16K. Yard were very quick to put their hand up and say it was down to them.

I'll tell that story one of these days.

Have had several lazy engine experiences caused by different things. Determining which engine was at fault was easy. Powering up each individually quickly showed which was not doing the job

There's one of the upsides to a single engine.

Was the transmission fluid darkened or smelling funny? Often a pre cruise day dip stick check can note a clutch pack problem.

As mentioned, the next steps will be interesting. Is he using the same guys to repair tranny as "fixed" the engines? Knowing who the right guys are is never easy.
