Yamaha Thermosensor Assy - Engine Monitoring Component - 67F-85790-00-00

Overview

When a Yamaha starts giving odd temperature readings or alarms that don’t quite make sense, the thermosensor is usually worth checking. This part monitors engine temperature and sends that info to your gauges or warning system. I’ve seen engines go into protection mode just because the sensor was off. When it’s working right, you get accurate readings and peace of mind while you’re running.
