Sierra 2 Inch Trim Gauge 68378P for Honda Outboard Engines

The Sierra 68378P is a 2 inch trim gauge built to monitor engine trim position (up-down) on boats powered by Honda outboard engines. It reads engine trim angle using a sender code matched to Honda's trim sender output, so the needle tracks accurately from full down to full trim-up.

The gauge features a stylish white bezel with black-on-white graphics for clear readability, plus enhanced illumination through both the dial face and the perimeter of the bezel for strong visibility at night. The glass lens is domed to shed water and resist scratching, holding up to the marine environment on the dash of any boat. The bezel measures 2.39 inches in outer diameter, and the gauge draws 0.10 to 0.15 amps during operation. Optional add-on eyebrow or square bezels are available separately for a different dash appearance.

This gauge is intended for boats with Honda outboard power where the trim sender uses a Honda-specific sender code; it is not interchangeable with Sierra gauges calibrated for other engine manufacturers' sender codes.
