Tachometer install
My Grampian 28 does not have factory installed tachometer - only oil pressure, temperature and ammeter gauges. Some owner before me installed an electronic gauge like on the picture but I don't think it's accurate. The minimum RPM it shows is 2800 when idle. Sometime it shows 5000 - 6000 when pull throttle to push the boat a little bit forward or reverse. All in all, it seems to be not working properly.
A couple questions I have. Which RPM gauge is recommended? How to wire it into the engine?
