Sierra Spark Plug Wire Set 18-8847-1, Replaces 67F-82341-00-00, Fits Yamaha F75/F80/F90/F100 Outboards

The Sierra 18-8847-1 is a complete set of spark plug ignition wires engineered for Yamaha F75, F80, F90, and F100 outboard engines. Each wire uses a durable stainless steel wound conductor for maximum horsepower and engine performance, paired with corrosion resistant stainless steel spark plug and distributor terminals for maximum conductivity. A Kevlar core reinforces the wire for long-term durability and long service life, while premium silicone jacketing and boots provide ultimate high temperature protection where the wires route near the powerhead.

These wires also deliver superior RFI suppression, keeping electromagnetic and radio frequency interference away from sensitive onboard electronics and engine control systems while still delivering full voltage to each spark plug. The set is built to an exact fit design so installation is straightforward and matches the original wire routing and connector style, restoring reliable ignition performance on applicable Yamaha outboards.
