🔧 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

The gauge receives an engine-speed pulse and warning inputs from the outboard. It processes those signals to display RPM, trim position, operating time and visual warning information.

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

📦 Condition

• Genuine used part

• Removed from running engine installation where applicable

• In good working condition unless otherwise stated

• Harnesses are not included unless specifically stated
