1985 Evinrude 70hp outboard


New member
I recently purchased an older boat with a 70hp Evinrude outboard motor. As is normaal with a lot of older boats they have a few issues, the speedometer & tach both do not function. I am trying to find any information or help that may be out there, I am looking to get them both back up and working, it is on a 1983 Ranger 335v bass boat so it is not original to the boat. The tach I am assuming is electrical but the speedometer I am unsure of. Any and all help is appreciated.
