I finally got my new to me boat, I just took it out today, the tach reads what appears to be correct for awhile then continues to climb. Full out it was showing between 7-8,000. The back of the tach just plugs in, it's not digital. Anyone know what I can do to fix this? Do I just need to get a new tach?
Mine is doing the same thing. I just had he boat in the shop and motor is fine. I think it is the tach. It works fine most of the time but goes up to 6500 at wide open. I am guessing it is just a tach.
I moved all of the connenctions, then rotated the adjustment dial in the back making sure that it was put back in the original position, my tach works fine now. May try that before you buy a new tach.
