Sierra 62729P Premier Pro Water Temperature Gauge, 120-240F, I/O and Inboard

The Sierra 62729P is a Premier Pro series water temperature gauge built for I/O (inboard/outboard) and inboard boat applications. It reads engine coolant temperature across a 120-240 degree Fahrenheit dial range and requires a sender coded "D" to operate correctly. The gauge uses a black dial face with white graduations and numerals, plus metric markings in blue, paired with a white pointer staff for clear visibility at a glance.

Premier Pro instruments are built with full automotive-type lighting that eliminates the "halo" effect seen around the dial edges on lesser gauges. When lit, the white dial graduations glow red and the pointer illuminates white, so the gauge stays easy to read at night without washing out. The curved glass lens is scratch resistant and set into a black, near-flush bezel, and the housing carries a fog-resistant design that meets SAE J-1810. The gauge is rated IP65 for ingress protection and operates across a -40C to 70C range, drawing 0.10 to 0.15 amps on a 12 VDC system.

Physically, the gauge has a 2.39 inch bezel outer diameter and mounts through a 2.13 inch panel hole, matching the standard cutout used across the Premier Pro instrument line. It is part of the Premier Pro "Inboard/Sterndrive" instrument set, so it can be paired with matching gauges from the same series for a consistent dash layout. Optional add-on eyebrow or square bezels are available separately for a different dash finish.
