UANOFCN Universal Kill Switch for Outboards — Yamaha 6–40 HP Replacement with Safety Lanyard, Brass Contacts

The UanofCn Universal Kill Stop Switch with safety lanyard is a direct-replacement emergency engine cut-off designed to fit many 2-stroke outboards including Yamaha 6, 8, 9.9, 15, 25, 30 and 40 HP models.

This compact kill switch assembly provides a straightforward way to interrupt ignition when the operator is unexpectedly separated from the helm. Manufactured from polyurethane, rubber, ABS and brass components, it combines lightweight construction with corrosion-resistant contact points to suit saltwater and freshwater use. The unit corresponds to common OEM references (6E9-82575-02-00 and related numbers) and works as an aftermarket alternative for Yamaha, Honda, Tohatsu and similar outboard motors.

How does this kill switch stop the engine in an emergency?

When the attached lanyard pulls the keyed plug from the switch housing, the electrical circuit to the ignition is broken, which shuts the engine off immediately. The simple mechanical design keeps failure points to a minimum and makes the device easy to reset—just reinsert the plug. No special tools are required for normal operation or replacement.

• Keyed plug disconnects to break ignition circuit instantly
• Positive brass contacts for reliable electrical interruption
• Easy manual reset by reinserting the plug
• Robust materials for frequent wet-environment use

Will this fit my Yamaha 2-stroke outboard?

This part is designed to match common Yamaha 2-stroke kill switch dimensions and electrical layout used on 6, 8, 9.9, 15, 25, 30 and 40 HP models. It is sold as a universal aftermarket replacement and lists OEM references so you can cross-check compatibility. If your motor uses one of the referenced part numbers, this will be a suitable substitute.

• Compatible with Yamaha 6–40 HP 2-stroke outboards
• Cross-references OEM: 6E9-82575-02-00 and related numbers
• Works with many Honda and Tohatsu outboards that share the same switch style
• Compare part reference to factory manual before purchase

How durable and weather-resistant is the safety lanyard kit?

The lanyard and switch assembly use polyurethane and rubber for the cord and ABS plus brass for the switch components, chosen to resist saltwater corrosion and repeated handling. The brass contact points maintain conductivity even in wet conditions while the ABS housing protects internal parts. Regular inspection and rinsing after saltwater exposure extend service life.

• Polyurethane and rubber lanyard resists abrasion and flexing
• ABS housing reduces water ingress and impact damage
• Brass contacts maintain electrical reliability in moist environments
• Lightweight construction minimizes added weight at the helm

How simple is installation and replacement?

Installation is intended to be straightforward: disconnect the battery or ignition power, remove the old switch plug, and fit the replacement using the same wiring and mounting location. The unit’s universal form factor means most replacements require minimal modification. If wiring colors or terminal styles differ, consult a wiring diagram or a qualified marine technician.

• Basic plug-and-play fit for matching OEM-style terminals
• No specialty tools required for typical replacement jobs
• Follow manufacturer wiring diagram for non-standard setups
• Professional installation recommended if unsure about boat wiring

Who is this for? Boaters who need a cost-effective, durable emergency stop solution for small to mid-range 2-stroke outboard engines will find this UanofCn kit useful. It’s aimed at owners of older or replacement-style Yamaha, Honda, Tohatsu and compatible motors who want a functional aftermarket kill switch and lanyard that meets common OEM form and fit references. Ideal for recreational skiffs, small fishing boats, dinghies and tenders where a reliable operator cut-off is required.
