I recently purchased a 1988 Whaler Montauk 17. The boat is equipped with a 1988 Johnson SPL 88 HP motor. The tachometer doesn't seem to be working. Where should i begin trouble shooting to get this working again?

What brand might this tachometer be?
Do you have any other gauges? Do they all work?
Do you have a Voltmeter? This is where I would start.
Either a Voltmeter or Fish Finder that shows the charging system is working or not.
Here is a partial list of OMC style gauges.

If your charging system is not working, then you most likely need a Voltage Rectifier for your model outboard.
This in only an example.
Make sure whatever you purchase is the proper one for your motor.
