Gaffrig’s Drive Temperature Gauge allows a boater to monitor the oil temperature in the sterndrive or outboard. Useful for both new or recently rebuilt drives, this gauge clues the boater in on quick rises in oil temperature, heading off damage caused by partial seal failure or excessive friction on interior parts. The sender for the gauge mounts in the oil breather vent hole and the whole unit is easy to install. The gauge fits in a standard 2 1/16″ cutout and includes a probe, stainless braided cable and a through-hull fitting. The suggested retail price is $229.
