🔧 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.

The gauge displays engine RPM and additional operating information including trim position, warning indicators and operating hours when connected through the correct Yamaha harnesses. The -83 version is primarily associated with 2004-and-earlier rigging architecture, although later engines may use it only with the correct harness and configuration.
