Sierra 68403P Trim Gauge, 2 Inch, Honda Outboard, Up-Down Range, By Engine Manufacturer Sender

The Sierra 68403P is a 2 inch trim gauge built for Honda outboard engines, displaying trim and tilt position on an Up-Down dial range with a By Engine Manufacturer sender code. The gauge face uses white and blue graphics on a black dial background for clear visibility, and U.S. And metric scales with ISO symbols make it easy to read regardless of the reference system in use. A scratch-resistant domed glass lens sheds water and resists scuffing over years of use at the helm, while a low-profile bezel follows the curve of the lens to eliminate water trapping around the edge. Perimeter lighting illuminates the gauge for accurate readings at night or in low-light conditions. The 68403P is intended to replace a worn, fogged, or non-functioning trim gauge on a Honda outboard installation, restoring accurate trim position feedback at the helm. Its compact 2 inch size fits standard dash cutouts used across many helm layouts, and its sender code compatibility is matched to Honda outboard trim senders rather than a universal signal, so it reads correctly without recalibration. This is a genuine Sierra gauge, sold as part number 68403P.
