Went out on Memorial Day to give my boat a shake down. Have not been in the water for almost a year. Ran the engine on the trailer at home during the winter. I guess it is not a good thing to let a diesel engine sit too long if it has a turbo. Started out bad and got worse. Couldnt find the boat drain plug. Found a new one after about 1 hour of tearing everything up around the area of the sink, which is were I faithfully put it all of the time. Then vessel assist brought in a sailboat that went on the rocks. He came my way so I helped them out. Coast Gaurd was there doing there paperwork and I asked if they would do me a safety ck. Said yes but after 45 minutes with the other guy they said they had to leave so I asked what they ck for and I found my flares expire in Jan. He said I needed two extinguishers and I only had one but have 2 halon as a back up. So flew over to West Marine and got the 2 xtinguishers and day/night flares. Almost got the wrong ones. day only. So I take a few relatives for a short boat ride to see how the boat runs. Took her up to 2000 and temps, oil press and volts seemed good. Got out to the bait barges and started to throttle up and seemed like no more speed, turned to ck exhaust and it looked like a black hurricane following me, twirlying black smoke. . Back to dock, cked turbos and both would not turn. Toady is another Day and things went differently. Pull ed off the air cleaners again to remove filter housing and used a 15 mm open end to turn the turbos. Stbd more difficult. Port turned a few times and it turned easily. Anybody know of any carbon cleaning additive methods to add into the fuel? John B. said to removed exhaust elbow and file off the carbon. I need new air cleaner housing. Someone posted something ahwile back on converting over to different air cleaners. Has anybody modified the old style air cleaners for the TAMD 41?
