Well let's start off by saying 1st my old tach would read from 0-2000 rpm no more (no matter how fast). The boat would do 34mph. I said wow tach must be going out so Faria said send it back so I did and a nice new one came so I verified the pole setting and no the darn gauge reads 0 no more no less. What is up?<br />Boat 1987 21' Trophy w/ 125 Force, verified speed w/ GPS and what should I look at next (The Rectifier)?
