I have a 92 Carver with two 454 Crusaders (330 Hp). I have recently noticed that at cruise speed (3600 rpms) I am seeing a periodic fluctuation in the sync guage and tach on the starboard side. Sometimes the drop/dip is minor and sometimes it is pretty severe. Really don't notice much in the sound or feel of the engine per say but at that speed I don't think I would. At lower speeds (idle-2500 rpms) everything is fine. I suspect the starboard engine coil is breaking down under load but I wanted to ask for some opinions here first before replacing. Thanks for the help.
