Hello, I have a survey on Monday and no way to get to a mechanic or diagnostic reader for a code before then so I hope some of you have some ideas with all your experience. I have a 2007 320 Sundancer with 2 350 mercruiser mag mpi with v drives. My starboard engine will go wide open throttle with the trim tabs up to about 4550 rpm and my port engine will go approximately 4800-4850 rpm at WOT. If I have the trim tabs down and go WOT the rpms are about 200 less on each engine and maybe 2-3 mph slower but no problems and no alarms. When I put the trim tabs up and go WOT at the full rpms I described above the starboard engine is fine at the 4550 rpms but the port engine at 4850 runs great but after 5-10 seconds I get an alarm and the engine doesn't shut off but goes into safety mode. Any ideas of what this could be and how to fix it. Thank you for your help
