Diesel Engine Smoke
What is the normal exhaust for a marine engine? Should there be visable exhaust when engine is warmed up and ideling? When the engine is warm and running at high rpm and nearly full output should there be any visible engine exhaust, if so what color. I know black exhaust is bad (overloaded engine) and blue smoke may indicate burning oil, but what is a normal color if any at all? Would you normally see visible water mist from the sea water cooling coming out of exhaust?
