A few days ago while fueling my 330 Signature, I was checking my fuel gauge at the helm and an alarm sounded and the display read EVC System Error, Contact Volvo Penta Workshop. I shutdown and restated and the error cleared and everything was operating normally. Yesterday, I took the boat out and shortly after getting up on plane, an alarm sounded and my display read high exhaust temperature, contact Volvo Penta Workshop. My temp guage read 200 but once I reduced speed the temp quickly went down to 160. I shut down for a moment and restarted and everything seemed to operate normally but I returned to the marina. It seems I need to have a EVC System diagnostic run, but I was wondering if anyone out there has seen this issue. I plan to contact my dealer today. Thanks!
