"Hello, I have a 1992 Bayline
"Hello, I have a 1992 Bayliner 3055 powered by twin Mercruiser 5.0's (carbs). On the conclusion of a 70 mile trip I noticed a Clacking sound from the port engine when docking, the oil pressure was good, but I was at idle docking. Oil level full, Temp ok. I decided it was my imagination. Yesterday took the boat out and made it 7 miles out and noticed an RPM drop on the port engine that gradually became larger (600 to 800). Slowed to an idle and noticed the clacking, only louder, and the engine seemed to be making a louder exhaust noise. Then remembered to look at the oil pressure, there was none. Shut down the engine and returned to dock. I restarted after it cooled down. The clacking noise was gone but the louder exhaust noise was still there. The oil pressure was back also (35 psi).
Why would the pressure be good at a cool idle? Did I damage the engine? What should I do next?
Thank you"
