Marinco 12V Mini Marine Electric Horn — Compact 304 Stainless Steel, 106 dB, Pre-wired

The Marinco 12V Mini Marine Electric Horn is a compact, fully sealed stainless-steel horn that delivers 106 dB of sound from a small, easy-to-mount 12-volt unit.

This compact marine horn is built for boats and other small watercraft where space, corrosion resistance, and clear signaling are essential. Pre-wired for quick connection, the horn combines a robust 18/8 (304) stainless-steel cover and diaphragm with a sealed enclosure and a vibration-dampening pad to resist splash, salt, and vibration. Its small footprint lets you install it in tight spots while still producing a loud, recognizable tone at a fundamental frequency near 440 Hz.

How loud is this horn and what does that mean on the water?

The horn produces about 106 dB measured at one meter, making it audible over engine noise and wind at short to moderate distances. That level is suitable for signaling in busy marinas, rivers, and coastal waters when used according to local sound-signal rules.

• Sound rating: 106 dB at 1 meter
• Fundamental frequency: 440 ± 20 Hz for a clear, attention-getting tone
• Designed to be heard over typical onboard noise levels

How easy is it to install and power the horn?

The horn comes pre-wired and runs on 12 volts, drawing a maximum of about 3 amps. Its small size and included vibration-dampening pad simplify mounting options and reduce noise transfer to the hull.

• Electrical: 12 VDC, maximum 3 amp draw
• Pre-wired for fast hookup to an onboard 12 V circuit
• Compact dimensions allow flexible placement in tight spaces

Will it last in a marine environment?

Yes—critical components such as the cover, diaphragm, and mounting bracket are made from 18/8 (304) stainless steel, and the sound unit is fully sealed to limit water and salt intrusion. The design emphasizes corrosion resistance and durability for typical marine exposure.

• Materials: 304 stainless steel for cover, diaphragm, and bracket
• Totally sealed construction to protect internal parts from moisture
• Includes a vibration-dampening pad to reduce wear and mounting stress

What are the physical size and warranty details?

The horn's compact footprint suits small boats or crowded mounting zones, and a limited warranty covers defects for the first year. Check measurements and mounting access before ordering to ensure a proper fit.

• Dimensions: approximately 3" L x 3.25" W x 1.75" H (about 3 3/4" x 3" x 1 3/4" overall)
• Weight: about 11 ounces for easy placement
• Warranty: one-year manufacturer coverage against workmanship or material defects

Who is this for: The Marinco 12V Mini Marine Electric Horn is aimed at boat owners, small-craft operators, and marine technicians who need a high-quality, compact signaling device that resists corrosion, fits in limited spaces, and installs quickly on 12 V systems. It’s a practical choice for runabouts, sailboats, personal watercraft, and utility craft where reliable audible signaling and long-term durability are priorities.
