Servicing Tach

[Matysiak]

The tach on my 1980 115 johnson is sticking occasionally. If you tap it, it will register the RPM fine for a while, but ultimately sticks again. <br /><br />Can you service Tachs by adding some lube some where?<br /><br />Stephen

Re: Servicing Tach

Hi Stephen,<br /><br />Try looking for a poor or loose electic connection. I think OMC always used a grey wire for the tach feed. If it's loose it could be giving the on/off type reading you describe. Because it starts working when you tap it, check the wire connections on the back side of the tach first. A poor ground connection can have the same affect. <br /><br />Tachs are not serviceable. When they go, they go.<br /><br />The good news is that quality tachs are available starting at around $70 and up to $300. And they are really easy to install if you have easy access to the rear of the dash panel.<br /><br />Lots and lots to choose from at the Marine Mega Mall.<br /><br />Good luck,<br /><br />Mark
