Evening - I am having a high idle issue. I recently replaced my IAC on my 2006 Sea Ray Sundancer with 350's. The idle RPM is high on start compared to starboard engine. Port = 750 Starboard = 600. After running the boat and easing off the throttle but staying in gear the port rpm is 1000 and goes higher when shifting to neutral. Any thoughts or suggestions would be helpful, thank you!
