I have a 1997 370 Sundancer twin 3116's with 850 hours on it (I have put about 35-40 hrs on it since I bought it in January). While under way I have a faint "smokey haze" black/brown in color over the water. Not able to capture in a photo but can see from the boat. This seams to be coming from the underwater exhaust since I do not see it from the side by pass. I typically run at 1900-2100 rpm 60-65% WOT. I also will run low at about 1500 if towing my dinghy - no longer than an hour and a half. And after I tow it I will run it up around 2200 to burn off any carbon. Temps are from 175-190, and oil psi is right around 50.
My question - do any other CAT owners experience this? If so what have you done?
Again the boat runs amazing! Just don't want to be missing tell tell signs of a problem.
