🔧 Product Description

  

Genuine Yamaha 6Y5 Digital Multifunction Tachometer - Part Number: 6Y5-8350T-83-00

  

A genuine Yamaha 6Y5 multifunction LCD tachometer for conventional analogue-signal Yamaha outboard rigging.

🔌 Function

Common signs of failure:

  

• LCD segments are faded, missing or blackened

• Buttons no longer change the display

• RPM reads incorrectly because DIP switches are set incorrectly

• Trim or warning information is absent because the wrong harness is fitted

• Moisture has entered the display
