Good To Know

Q: Should I replace the valve seals at the same time? A: Yes, valve stem seals are typically replaced whenever a valve is removed to prevent oil seepage and maintain proper sealing. It is a low-cost step that protects the new valve.

Q: How can I verify this valve matches my engine? A: Check the part number 8GL-12121-10-00 against your machine's parts diagram or service manual. Model year and serial number can affect fitment, so confirm against your exact watercraft before ordering.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
