    Default I969 Model 40973R 40 HP Evinrude Tachometer.

    I would like to know how to set a 6M or 7M Tachometer and how to connect to a 'Generator' ?

    Is your motor electric shift ?---Do you have the generator / voltage regulator and the belt ?----Where did you get the tachometer ?

    Good question i believe the tach requires AC pulse and a generator produces DC voltage. I am not sure if you can pull a pulse from one of the ignition coils for a standard inboard tach? Tiny tach makes a induction type you just wrap around a plug wire and mount close to or on the engine it gives you rpm and hours. A single pulse from a two stroke is the same as a two cylinder four stroke with adistributor. The tiny tach would be a sure thing.

    The TT2A can be ordered with a longer coax from the factory it comes with 6foot standard coax.

    Yes, it is electric shift, with Generator, Voltage Regulator and Belt. Tachometers are from previous boats in the past.
