laffoonparts Boat Kill Switch Ignition 176408 Replacement for Johnson/BRP/Evinrude — Keys & Lanyard, Plug-and-Play

laffoonparts 176408 is a direct-replacement ignition cut-off switch kit for single-engine Johnson/BRP/Evinrude outboards that includes keys and a lanyard.

This compact ignition switch replaces part number 176408 and is built from reinforced ABS, PVC and metal components to withstand marine use. It arrives with a pre-drilled mounting plate, screws, a keyed lock cylinder and a flexible, tangle-resistant lanyard so you can quickly restore engine safety and control without hunting for hard-to-find OEM parts.

How does the replacement switch restore safety on my boat?

The kill switch stops engine power when the key is removed or the lanyard is pulled, preventing the boat from running uncontrolled. This replacement matches OEM mounting and wiring styles so it integrates cleanly with most single-engine Johnson/BRP/Evinrude control boxes.

• Replaces part number 176408 used on many Johnson and Evinrude outboards
• Keyed lock cylinder for positive on/off control
• Included lanyard releases engine power when disconnected
• Wiring harness with plug-and-play clasps for matched connectors

Will this switch fit and install easily on my outboard?

The unit ships with pre-drilled mounting holes and the necessary screws so it can be secured into most control box panels with minimal modification. Wiring is designed for a straightforward connection but if your boat has a non-standard harness you may need basic electrical adjustments or professional help.

• Pre-drilled mounting plate for quick attachment
• Mounting screws included to match common control boxes
• Plug-and-play wiring clips for standard harnesses
• Professional installation recommended for complex wiring

How durable is the laffoonparts ignition switch in marine conditions?

Materials selected for the switch—ABS casing, PVC insulation and metal contacts—offer resistance to vibration, humidity and routine marine wear. The mechanical parts are engineered for consistent engagement and to remain secure under typical boating stresses.

• ABS housing resists impact and UV exposure
• Metal contacts and key cylinder for reliable conductivity
• Vibration-resistant design prevents accidental disengagement
• Elastic lanyard with swivel hook minimizes tangling and wear

What comes in the kit and how do I use the keys and lanyard?

The kit includes the ignition switch assembly, a keyed set of keys, a flexible lanyard with a swivel hook, and mounting hardware. Insert the key to enable the ignition; attach the lanyard to the operator and the swivel hook to the switch so the engine cuts out if the operator is separated from the helm.

• Ignition switch assembly pre-wired for ease of connection
• Two matching keys for backup and convenience
• Expandable, anti-tangle lanyard with swivel hook
• Mounting screws included for immediate installation

Who is this for: This replacement is aimed at boat owners and marine mechanics who need an affordable, reliable copy of Johnson/BRP/Evinrude part 176408 for single-engine outboards. It’s ideal if you want an OEM-compatible ignition cut-off that’s ready to mount and connect, with spare keys and a flexible safety lanyard included. If your boat has a custom electrical system or you prefer factory servicing, consult a technician before fitting.
