2006 340 twin 8.1 496’s. My boat is in the water full time. I was doing an oil change and after sucking the oil out of the port motor, I noticed an oil slick B had formed on the water. The only place where I could think of where it would have come from is the underwater BNO exhaust. Ordinarily, there never is oil in the water. The port engine had water in the oil and how that occurred is still unknown which prompted the draining. Any ideas on how I would get oil in the water?
