Got a 2004 mercury 60hp elptefi 4 stroke bigfoot. the tach is showing 2500at idle but i know this cant be cause i cant hardly hear it. What should the poles be set at.My idle speed should be 725 from what the plate on the motor says..

What are your options. What is it set on now?
Looks like 12. Is this a new tach or did it just start doing this?
It's been on there when I got the pontoon only used it like 3 times then got a TBI so been like 3 years since I used it so to be honest I can't yell you wat it was then. I'll get a pic of the back in the am
It's a teleflex tach
Attachment 423333
It was set on 2p I tried couple of settings but no joy.
None of the settings brings it down to where the rpms should be?
I would take it to the 6p setting and see what the reading looked like
I'll try that soon as the down pour here in sc decides to stop :bash
Since that is wanting to be set for pulses, 6 would be the correct setting. Another words the stator has 12 poles producing 6 pulses for the tach and rectifier. Try turning the adjustment screw back and forth many times stopping at 6. This often cleans corrosion of the very small contacts inside the tach. If this don't help check your charging circuit. If it is working correctly then the tach is probably bad.
