Sierra 80590P Electric Water Temperature Gauge, 240 Degree F, 2 Inch, 12 Volt, for Inboard and Diesel Engines

The Sierra 80590P is a heavy duty electric water temperature gauge built for inboard and diesel engine applications. It reads temperature across a 120-240 degree F range on a 2 inch dial, giving operators a clear, at-a-glance view of engine coolant temperature so overheating conditions can be caught early. The gauge is constructed with brass and stainless steel components for durability in the marine environment and connects using a 1/8 NPT thread fitting.

This gauge operates on a 12 volt electrical system and requires a Sender D temperature sender to function; the sender is sold separately and is not included with the gauge. Sierra engineers its gauges to meet or exceed the performance of the original equipment they replace, standing up to the vibration, moisture, and temperature swings typical of marine helm installations. The 80590P is suited for boat builders, engine rebuilders, and owners upgrading or replacing an existing water temperature gauge on inboard or diesel powered vessels.
