I have a 1988 CD28 (open sportsfisher). She was a heavy smoker-200 Volvo TAMD with 510 hours at the time. My mechanic-guy who is an expert on Volvo's told me that my particualr Volvo model is a historic smoker. We replaced/upgraded the injectors (about $1000) which helped reduce the problem (but not totally eliminate it).
Since that time, I repowered to a 230 Volvo and am very happy with the results in terms of performance and noise levels. She now cruises at 18 knots at 3400 rpm and tops out at 20 or so. The new engine simply does not smoke. It is amazing.

I have an 1988 CD28 flybridge w/ the Volvo TAMD41-A. It smokes, but not real bad. After it heats up it is not bad at all. My Volvo mechanic told me that Volvo came out with the '-A' varient to the TAMD41 because the origional was a real bad smoker. I wonder if your boat had that first version of the engine? He told me that the only difference between a 41 and a 41-A was a slight modification to the cyl head for a little better combustion and the addition of a solinoid actuated exhaust gate valve to heat the engine up quicker to stop the smoking. I don't know if a you could retrofit an origional 41 with the modifications to the 41A or not. It might be cheaper than repowering.???

Interesting. I have TAMD41B's, now with about 850 hours. Never observed much visible smoke, but looking at the transom up close you can clearly see the soot.

BTW, the best thing I've found to remove diesel soot from fiberglass is to just go over it with one-step cleaner and polish, redoing any dirty spots until it's all cleaned off. I read somewhere that the synthetic cleaner/polishes (silicone or teflon) are better than wax because the soot combines with the organic wax. Never saw much difference but I use teflon polish on the transom anyway. But teflon or silicone may penetrate and reduce adhesion if the surface ever needs to be painted or caulked down the line.
