Yamaha, F70, 2016

My F70 is pegging out the tachometer at 6000 rpm at 15 mph. I don't think the motor is actually running that fast. Tach. reads 2000 rpm at idle. I think my tachometer is hooked up wrong, or is on the wrong setting, seems like it is reading double what it should be. Motor has been this way since I got it, I just never noticed it. How would I check the tach. setting? Thanks
