Cummins Diesel Engine issue
I have a 2005 3700 SY, twin Cummins 330's engines. We were cruising at 2400 rpm's all was good, I heard a huge swishing sound like high pressure released or a burst of air from an air gun. I loss power/rpm's in the starboard engine. Then could not get it above 1500rpm's?
All gages were normal, no smoke, no oil or gas in the bilge? I came in slow at 1100rpm's on both engines boat felt normal but could not rev up the starboard above 1500 rpm's? Any thoughts from anyone would be helpful
