Re: mercury tacho

Outboards must have a stator with four to twelve magnetic poles. This is where the tach gets its signal. Tachs (most modern) will not work on engines with magneto or lighting coil ignitions. You have the older ignition system and I think your mechanic is giving you the straight scoop.

Re: mercury tacho

buy a "tiny tach" for $35, hooks up to a plug wire<br />and ground & works on all motors.
