"Good morning.
I have twin 350 Mag engs in my 310 SeaRay with inboards. Port engine is rebuilt with 40 hours on it. Last week the port engine's rpms started to flutter (surges) and I have to add throttle above 3,000 and the syncronizer gauge would flutter with the port engine. Starboard engine is fine and holds rpms. Below 2,000 rpm both engines work fine. Do you think this is a fuel concern? (i.e. water in the gas? I use the same gas for both engines and the starboard works fine. Engine temp on the port engine is good and the motor is not using oil. Any recommendations for me to check is greatly appreciated. Thank you."
