Sierra 63480P Sterling 2 Inch Water Temperature Gauge, 120-240F, for I/O and Inboard Engines

The Sierra 63480P Sterling water temperature gauge is a 2 inch instrument designed to monitor engine water temperature on I/O and inboard (I/B) engine setups, reading across a 120-240 degree F range. The gauge face uses a brushed aluminum dial with black graduations, black numerals, and a black pointer for a clean, high-contrast look at the helm. Both U.S. And metric scales are marked on the face along with ISO symbols, making the gauge easy to read regardless of which measurement system the operator prefers.

The lens is a curved, scratch resistant glass designed to hold up to sun exposure, spray, and everyday wear at the helm without clouding or scratching over time. It is set in a polished stainless steel, near-flush bezel that gives the gauge a finished, factory-style appearance once mounted in the dash or panel. Perimeter lighting is built in so the gauge stays readable at night and in low-light conditions without a separate light kit. The gauge uses NPT threading for its sender connection. This gauge is intended for I/O and inboard (I/B) engine applications where a 2 inch water temperature readout is needed.
