What year F115 do you have and what gauges do you have now?

The motor- F115TLRY. The Tach is a Yamaha digital with boat trim icon at the top right, temperature and oil icons on the bottom and numbers 1 thru 5 on the right. A 10 pin harness comes out of the back. No other markings on the gauge except for a 97N stamped on the back. The motor is a 2000.

There really are no advantage for replacing tach, the new digital tach has a hour meter in it but not really worth the price to replace. If your tach is bad and need to replace it then order 6Y5-8350T-82-00 multifunction tach. The multifunction speedometer is 6Y5-83570-S5-00 and displays speed, fuel gauge, battery voltage, clock, trip meter.
