"I have a 1979 Evinrude 140.
"I have a 1979 Evinrude 140. The tach is a Teleflex Vector model and worked just fine last year when I winterized the boat. I recently was able to get the boat out for the first time and the tach wasn't working properly. It reads about 1400RPM at idle and then quickly jumps to 4000 and then well past 6000 at only about 2/3 throttle. I know that I wasn't turning anything past 5500 when the tach last worked. Also the indicator needle does not stay steady but bounces around up and down while running at a constant throttle.
So, does this sound like a have a bad wire, is the tach itself bad, or do I have a rectifier that's starting to act up?
Thanks in advance for any help.
