Review on ⛽️ Improved Water Temperature Gauge Sender 806490T for MerCruiser Stern Drives and Inboard Engines - Quicksilver Engine by Gary Newman

This was the second shipment of this item. The first sensor caused the dashboard to become erratic and eventually locked up. I thought the gauge was dead. This was an update to replace a 20 year old OEM. Eventually found the sensor was faulty, contacted Revain and they sent another. Simple installation with a plug connection on the thermostat housing. Works as it should, so far only with a short engine start. The 4 stars reflect my problem. The thermistor works against the temperature.
