UANOFCN Outboard Kill Switch & Lanyard — Fits Yamaha 6–40HP, Brass Contacts, Water-Resistant

UanofCn Universal Kill Stop Switch with safety lanyard is a direct-replacement outboard engine kill switch designed to cut ignition quickly for Yamaha and many other 2-stroke outboards (6–40 HP).

This compact kill switch assembly provides a simple, mechanical safety cut-off for small outboard motors. Built from polyurethane, rubber, ABS and brass, the unit is weather-resistant and lightweight so it withstands marine conditions while remaining easy to clip onto a tiller handle or console. It’s listed as an aftermarket equivalent to Yamaha OEM refs 6E9-82575-02-00 / 6E9-82575-00-00 / 6E9-82575-01-00 and fits many popular 2-stroke models including 6hp through 40hp engines.

How does this kill switch stop my outboard quickly?

The switch interrupts the ignition circuit when the lanyard is pulled free, shutting the engine down immediately to reduce risk if the operator falls overboard or is dislodged. Its brass contacts and ABS housing ensure reliable electrical separation each time the cord is removed.

• Mechanical pull-tab design disconnects ignition contact instantly
• Durable brass contacts for consistent electrical cut-off
• Water-resistant ABS and rubber components for marine use

Which engines and models will this replace or fit?

This UanofCn unit is marketed as a universal replacement compatible with many small 2-stroke outboards. It specifically replaces Yamaha OEM references and fits 6hp, 8hp, 9.9hp, 15hp, 25hp, 30hp and 40hp 2-stroke models, and is commonly used with other brands like Honda and Tohatsu when mounting and wiring match.

• Direct aftermarket match to Yamaha refs: 6E9-82575-02-00, 6E9-82575-00-00, 6E9-82575-01-00
• Compatible with many 2-stroke small outboards from multiple manufacturers
• Suitable for tiller-handle and console installations where wiring terminals match

What materials and features make it reliable in marine conditions?

The lanyard and switch assembly combine polyurethane for the cord, rubber seals for splash resistance, ABS for a tough outer shell and brass for electrical contacts. These materials balance durability and light weight so the switch resists corrosion, remains easy to operate, and endures repeated use in wet environments.

• Polyurethane lanyard resists stretching and UV damage
• Rubber seals reduce water ingress into internal parts
• ABS housing withstands impact and sun exposure
• Brass electrical terminals reduce corrosion and ensure conductivity

How do I install the UanofCn kill switch and lanyard?

Installation is straightforward for electricians or mechanically inclined boaters: remove the old switch, match the wiring terminals to the new unit, secure the housing to the mount, and test before launch. Ensure power is off while wiring and confirm the ignition cuts when the lanyard is pulled.

• Turn off battery power before starting installation
• Match and secure wiring terminals to the original connections
• Mount housing where the lanyard can reach operator position
• Test function with engine on idle in a safe environment

Who is this for: boat owners, fishing guides and fleet operators who use small 2-stroke outboards and want a reliable, low-cost replacement kill switch that matches Yamaha OEM references. It’s ideal for those needing a weather-resistant, easy-to-install safety cut-out for tiller or console controls on 6–40 HP engines, or anyone replacing a worn or lost lanyard assembly with a universal aftermarket option.
