I have a 1976 35 hp Johnson outboard with pull start. So there is no electric at all on the motor. Is there anyway to hook up a tach?

Back in the day, lots of people would install these on their 2 cycle snowmobiles, lawnmowers, etc,etc. Can get as just a tach or hourmeter and tach.

Are you SURE your motor doesn't have a charging stator? Even a pullstart motor of that vintage might still have one.

Outboard tachs usually run off of the 12-pole charging stator.
I did have an old 33hp Evinrude that had an external generator for charging. I tapped into the coil trigger, and set a car tach to "4 cyl" mode. It would read 50% of what the motor was turning.

(each cylinder of a 2 stroke motor fires every rev - a 4 stroke 4 cylinder fires twice each rev).

TinyTach works okay, but I've had several of the cheap ones go bad pretty quickly.

No charging coil at all. Just two black wire leave motor and they go to the cut off switch. So Im assuming no charging capailities cause I thought the same thing. This is a 2 cylinder 2 stroke motor. Do they make a tach with a pick up wire that can be wrapped around a plug wire, like a timing light pick up?

See the link above for the TinyTach. It wraps around the plug wire just as you describe.

But HEY, I just found this:

It'll work.
