Tiny Tach for my Johnson V-4 ?

[BonairII]

I've finally decided to get a portable tach(probably a Tiny Tach) for my '67 Johnson V-4 80hp...and I don't know which one I need.

I've searched here, but I'm still not sure which one is right for my motor.

The normal Tiny Tach for gas engines set at 1 spark/rev.

Well they only have 3 to choose from. The standard, the commercial and one for diesels. You need the TT2A unless you want a few more features that the commercial has.

This one will do the job......

You will need to advise them what cable length you require as they only come standard with 6 feet, which isnt long enough. It needs to be set at 360deg to give the correct reading for your motor.....
