Under their cosmetic cover, all Sea-Dog MaxBlast electric horns have a steel base housing. Unlike some other brands, this steel housing is triple protected from corrosion by a red primer paint followed by a baked-on automotive paint coating which is then covered with an over-molded plastic cover to provide complete protection from the marine environment.
(Physics dictates that the base housing must be steel in order for the copper coil actuator to create the magnetic field which causes the stainless steel diaphragm to vibrate - making the horn sound.)
In fact, MaxBlast horns are so well protected from salt corrosion that they have passed numerous standardized ASTM-B-117-11 600-hour saltwater spray tests with no signs of rust or corrosion. As a result, Sea-dog offers an unusually long 5-year warranty on all MaxBlast horns.
This horn is a drop-in replacement for many common OEM horns, with a matching bolt hole footprint.
