Got an issue and it seems like Volvo diesel techs are impossible to find.

I think I self inflicted this however it may very well be something else going on. I explained my problem to a Volvo tech and he said my turbo is probably sooted up so just go out there and floor it for at least 10 minutes which I did and sadly it changed nothing. Apparently running low rpm for extended times on Volvo diesels, causes the turbo to get full of soot and the turbo does not spin freely.

Have not put her on step this year and went to do so last week. My Starboard engine is not producing the proper power as it will not go over 2550 rpm. The port engine manages just 3050. When full power is available from both, I can attain 3650 rpm on both easy. Since the weak engine is not helping the good engine I can see it is not coming up to rated RPM as it simply does not have the power to do so without help of the starboard engine.

Turbo when running WOT is giving me 200kpa on the port however only 110-120kpa on the starboard so definitely a turbo boost issue happening not allowing the engine to produce the rated power.

Both engines fire up instantaneously and purr like kittens and run great at hull speed. My Starboard engine has been giving off a little smell/smoke (black) since the beginning of last year+ so something is not perfect on that side and may have been a warning something needs attention.

Now I do know quite a bit when it comes to mechanics but diesels are like Chinese to me along with Turbos. One of my friends is a Diesel specialist and he is pointing me to a probable waste gate issue which could be stuck partially open not allowing enough exhaust pressure to spin up the Turbo to its rated rpm.

Anyone have any info or suggestions that could possibly help me out until I find a Volvo Diesel tech? I am leaving on vacation on the boat tomorrow so timing of this sucks then again I do like to travel hull speed any way so not the end of the world being our plans were to stay in about a 100km radius from home port.
