Okay let's start off with my motor, I have a 115hp outboard Evinrude, model#115793S. Not too long ago I replaced my non working tachometer with a new Faria tach. The old one was a 6K so I replaced it with a 6K, I also replaced the rectifier. The old rectifier had burnt up wires. Now when I give it gas in neutral, or in gear in the water; about halfway into the throttle my tachometer pegs out. Sometimes when I turn off the motor the tachometer needle stays pegged out at 6K....motor is not running, that can't be right. Did I hook it up wrong or is there something I am overlooking?
