SeaStar 68405P Trim Gauge, 2 Inch, for Mercury, Mariner, Force, Cobra, Volvo Penta DP/SX, Yamaha 2001 & Up

The SeaStar 68405P is a 2 inch trim position gauge that displays engine up-down trim position on a low-profile, curved black dial with white and blue graphics. The domed glass lens sheds water and resists scratching, and perimeter lighting around the bezel keeps the dial readable at night. The scale is marked in both U.S. And metric units, with ISO symbols where appropriate, so the display reads clearly regardless of the boat's other instrumentation standards.

This gauge is designed for a sender that is coded by engine manufacturer, meaning it pairs with the trim sender built into the specific engine or drive rather than a universal sender. It is intended for use with Mercury outboard and inboard-outboard (I/O) drives, Mariner, Force, and Cobra powerheads, Volvo Penta DP and SX drives, and Yamaha outboards from 2001 and up. The low-profile bezel follows the curve of the lens to eliminate water trapping around the mounting ring, helping keep moisture out of the housing over time.
