It's for an 80s OMC with a 5 pole stator right?

If so, you need one that says it's for an outboard w/ charging system that can be set to 5 poles or 10 pulses per revolution. A lot of the old airguides you see on ebay are for outboards with different ignition systems (there were a lot in the '60s and 70s) and will not be compatible with your outboard. Unless the seller has specific knowledge of what outboards their tach will work on, or you can precisely ID the model, those tachs are pretty well worthless.

Less than 70hp = 10 pole 5 pulse. all sea drives and all other models = 12 pole 6 pulse.
