I have a 2012 31' Coronet with 6.0L Crusader engines, with 384 hours. My port "red" check engine light comes on a start up and the "buzzer" is only intermittent. The temperature, oil pressure and voltage are the same for both engines and the boat runs great.
My mechanic is stump. Any suggestions and comments would be greatly appreciated.
Thanks
Rick
