Bad Tachometer - Need replacement.

Post by bjanakos »

I'm driving along one day and noticed my port tach was well above my normal running reading. I pulled back and noticed the boat was not running right, or sounded right. I usually synch by ear, and throttled back up until it sounded right, despite the tach reading. Also, my throttles were relatively even which is also a normal condition. So I continued on.....

To validate once I got back to the dock, I switched the sender wires on the tachs and sure enough, the problem stayed with the port side tach. So I figure I will change them both, but I am looking for suggestions on suitable replacements. Perhaps something that has a multi-function to add some more data to the bridge.

Thanks in advance.

If you haven't already, before swapping them out try the Cylinder adjustment on the back of it (if you have one)... There is usually a little dial where you can set the tack for 4cyl, 6cyl, or 8 cyl so it can be used with different engine types. Sometimes corrosion causes it to read a bit funky, so turning this dial back and forth a few times and setting it back to 8cyl cleans off internal contacts a bit and helps it read correctly.
