Got a 2000 Yamaha F80 carbureted with 703 control, runs well but need to hookup tach to monitor RPM.. I tried to hook up the analog gauge from 95 yamaha 90 HP 2 strokes but no response... Red wire to pos, green to sender, blk to ground..pls advise
Best regards.

I would think the Tach should have some dip switches or other way to set it for a 4 stroke etc.

Thanks Admiral, I also used Actron Digital Volt Meter w/ rpm, dwell.. features but had no luck either. Would the Yamie multi-functions gauge work.??

find a manual/instructions for the tach you have . it will have how to set the tach to match a motor, and if it is capable of being used on that 4 stroke.
the ones I have een has a switch under a rubber plug on the back or some dip switches
