I have a 2017 Cruiser 390 Express with 8.2L MAG Mercruisers with B3 SeaCore X Drives. Yesterday a "misfire detected" alarm popped up on VesselView for the port engine. I also notice that there is a small belt squeal on this motor upon starting. The engines run perfectly fine. Would these two problems be interrelated? I will schedule it for service, but was wondering if anyone else had this problem.
