So while out this past weekend I noticed that my tach's were reading 3K both but the syncronizer gauge showed it was way off? They sound more even when the syncro is straight up but then my port tach shows about 500 rpm less than the starboard. Anyone ever have this issue and how was it resolved? Here is a picture of my tach's and syncronizer from this weekend. BTW, the previous owner replaced the tachs at some point, don't know why but maybe related to this??
