Sea-Dog 431230-1 Drop-In Hidden Horn V.2 with Grills, 108 Decibel, For Vessels Under 39 Feet

The Sea-Dog Drop-In Hidden Horn V.2 with Grills, part number 431230-1, is a compact marine horn designed to mount flush into a helm or dash panel, keeping the horn body hidden while only the decorative grill shows on the surface. The kit includes the horn itself plus one chrome and one white decorative billet snap-in grill, so you can match the finish to your boat's hardware. Constructed of powder coated steel and injection molded nylon, the horn is built to hold up to marine conditions while resisting corrosion at the visible components.

Electrically, the horn draws 4 amps at 12VDC and produces 108 decibels at a frequency of 370 Hz plus or minus 20 Hz, meeting US Coast Guard COLREGS requirements and ABYC standard A-23 for vessels under 12 meters (39 feet). It carries NMMA Type Accepted certification #2577065. Installation requires a cutout of 1-7/8 inches by 3-3/8 inches, with the horn measuring 4-7/8 inches by 2-3/4 inches by 4 inches by 3-3/8 inches overall and weighing 0.72 pounds. This is a universal drop-in fit for boats needing a code-compliant, low-profile horn rather than an exposed trumpet-style unit.
