Sierra Exhaust Seal 18-0617 for Yamaha F75/F80/F90/F100/F115 Outboards, Replaces 67F-45127-00-00

The Sierra Exhaust Seal, part number 18-0617, is a replacement seal engineered for the exhaust system of specific Yamaha four-stroke outboard engines. It is designed as a direct equivalent to the OEM Yamaha seal, restoring a proper exhaust seal at the point it is installed and helping prevent exhaust leaks, water intrusion, or loss of exhaust pressure that can occur once the original seal wears out or hardens with age and heat cycling.

This seal is intended for outboards in the Yamaha F75, F80, F90, F100, and F115 model range, and is a routine maintenance and repair item for owners servicing the exhaust system on these engines. Replacing a worn exhaust seal with the correct part helps maintain proper engine operation and prevents secondary issues that can result from an exhaust leak going unaddressed. At 0.7 pounds, it ships as a compact, easy-to-handle component suited for do-it-yourself installation or use by a marine service technician during a routine exhaust system service.
