Hello All,
I own a 25Ft motorboat with two Yanmars. The port engine was blowing thick black smoke the other day and the rpm would not go above 2000 rpm.
I thought maybe a sticky turbo so I took off the inlet filter to check. Yes it was a bit sticky but i did also notice that two of the blades are damaged. so for now the engine is not producing black smoke as I freeŽd up the turbo and the rpm is going to maximium. however I think I should change the compressor wheel. Please can someone advise me how to do this.....? is there a special technique or is it just a case of removing the casing etc and removing the wheel with a puller...?
any advice greatly appreciated..
