Blue Sea Systems WeatherDeck Toggle Switch Boot, For WeatherDeck Panel Switches, IP67, Black

Overview

The Blue Sea Systems 4138 is a black WeatherDeck toggle switch boot that replaces the dress nut on compatible WeatherDeck panel switches. It adds a sealed finish around the toggle opening and carries an IP67 rating for temporary immersion up to 30 minutes. The threaded brass fitting is 15/32"-32, which matters when you are matching it to the correct switch hardware.

This is a small but important replacement part for boats with exposed switch panels at the helm, in the cockpit, or anywhere spray, rain, and washdowns are part of normal use. It is not a standalone switch. It is the boot and mounting piece used with Blue Sea Systems WeatherDeck toggle switches, so the buyer can restore the original weather protection without replacing the full switch assembly.

The black finish keeps the look consistent on WeatherDeck panels, and the UV-resistant material helps the boot hold up better in sun-heavy installations where rubber parts can fade or crack over time.

Key features

• Replacement boot for Blue Sea Systems WeatherDeck panel toggle switches
• Replaces the dress nut as part of the switch mounting hardware
• IP67 rated for temporary immersion up to 30 minutes
• Black boot with UV-resistant material for exposed helm and deck locations
• 15/32"-32 threaded brass fitting for correct switch fitment

Compatibility and fit

This boot is used with Blue Sea Systems WeatherDeck toggle switches, including models 4150, 4151, 4152, 4153, 4154, and 4155. It is a fit-sensitive part, so matching the WeatherDeck switch family and the 15/32"-32 thread is more useful than comparing it by appearance alone.

For boat owners replacing a cracked or worn boot on an existing WeatherDeck panel, this part makes sense when the switch itself is still working and the goal is to restore the panel seal at the toggle opening. That is common on center consoles, RIBs, small runabouts, and other boats where switches sit in wet, sun-exposed locations.

Installation and use

The boot installs in place of the dress nut on the compatible switch. On a working panel, that makes it a straightforward service item during panel refresh work or when a boot has split from age and UV exposure. Once fitted correctly, it helps maintain the switch opening against spray and routine washdowns.

This part is a good match for buyers who already have a Blue Sea Systems WeatherDeck panel or switch and need the correct replacement hardware rather than a universal toggle boot.
