I have a 2003 Merc90 3 cyl. that mixes oil with gas at motor. Tach is showing over 6000 rpm when should be 5400. There are several settings on back of tachometer 2p/4c, 3p/6c, 4p/6c, 5p and 6p. It is set on 6p but could have been moved. Any help from you Mercury experts would be appreciated. Thanks
May want to check here for the ansewer.
Thanks, I'll give it a try.
