Tach for '66 Evinrude Lark 40hp

I want to add a tach to the dash, I found one that matches the existing speedo. I'm asking advice on compatibility with the 2 cylinder magneto breaker ignition engine that has a generator rather than a rectifier. There are connections for Gnd, Ign, and Send. Gnd and Ign are obvious, the Send I assume, is for the tach wire connected to the safety cut-out switch which is wired to one of the points. Correct? There is a dial with settings marked A, B, C. Which of these should it be set to? Would that be for 2, 4, 6 cylinder engines? And is this the type of tach for this type of electrical system? See pic. Thanks!

Wow, you just might have found a tach for your magneto motor. They are kind of rare and hard to find. Having said that, let's see if others recognize it. What does it say hidden by the bracket?
 
I Think what you have there is the "Standard Tach" # 6 & 7, which are appropriate for your 40hp.

Well, I haven't purchased it yet, wanted to check out the compatibility. It is a Teleflex Morse, 8,000 rpm top end...

When I enlarge the pic, I see the word "ALTERNATOR". The engine has a generator, no alternator. So this is not the right type of tach. And that was confirmed by a guy on the antique outboard motor club forum... So thanks for your interest!
