Troubleshooting & FAQ
How do I know if my cylinder gasket is failing?
Common signs of a failed cylinder gasket include engine overheating, a noticeable loss of power or compression, milky or discolored engine oil, white smoke from the exhaust, or visible external leaks of oil or coolant from the seam between the cylinder head and block.
Is this gasket compatible with both standard (F) and counter-rotation (LF/FL) models?
Yes, this gasket is designed to fit standard rotation (F-series), counter-rotation (LF-series), and other model designations (FL-series) within the specified Yamaha 200, 225, and 250 horsepower 4-stroke families.
What is the difference between 69J-11351-11-00 and the newer 69J-11351-12-00?
The part number 69J-11351-12-00 is the latest version from Yamaha, which supersedes the older -11-00 and -10-00 suffixes. This typically indicates minor improvements in material or design for better performance and longevity. Our aftermarket part is built to meet or exceed the specifications of the latest version.
Do I need to use any sealant when installing this gasket?
This gasket is designed for a dry installation. Applying additional sealants can interfere with its ability to create a proper seal and may cause issues. Always follow the specific instructions in your outboard's official service manual.
