I own a 1989 Aquastar 33 fitted with TAMD 41B engines (200 hp) which smoke quite badly when cold, and still quite noticeably when warm. I have just had new injectors fitted in the hope that the problem would be reduced (or even eliminated) but it has made no difference. Engine oil consumption between services is nil. They have each done about 1800 hours but have been regularly serviced. I realise that it may just be a feature of these engines which I have to live with, but any ideas or thoughts would be very welcome.

To make things worse with the dingy in position and the bathing platform there seams to be a back draft witch brings the smoke back to the back of the boat an leaves it full of soot. The problem i the same when warm. It is driving me nuts. I own a 1989 Aquastar 33 fitted with TAMD 41B engines (200 hp) which smoke quite badly when cold, and still quite noticeably when warm.

Having said that I think your comment on oil consumption being nil could be a clue, it should not be nil unless you are at 10-30 hours after fill-up and if it is you may have to much oil in the combustion chamber and diesel taking its place in the sump. Perhaps a oil analysis would be an cost-effective next step.
