Real-World Testing: Putting Sierra International Shift Cover Gasket to the Test
First Use Experience
The primary test involved installing the Sierra International Shift Cover Gasket on my OMC stern drive, followed by a day of boating on a local lake. The conditions were relatively calm, with minimal chop and moderate temperatures. The real test would be the submersion and the effect of any leaks.
The gasket’s initial performance was excellent. Shifting was smooth and precise throughout the day. I was able to engage forward, neutral, and reverse gears without any hesitation or grinding.
Installation was relatively easy with basic tools, however, I did need to consult a few online videos for the proper torque specifications to ensure a proper seal without overtightening. There were no leaks noticed during my initial testing.

After several weeks of use, including multiple trips to the lake in varying weather conditions, the Sierra International Shift Cover Gasket continues to perform flawlessly. There are no signs of leaks or degradation of the gasket material. I am extremely pleased with how well it’s holding up.
The gasket has shown no signs of wear and tear, even after prolonged exposure to saltwater and fluctuating temperatures. This speaks to the quality of the materials used in its construction.
Maintenance is minimal, consisting primarily of visual inspections for any signs of damage or leakage during regular engine maintenance. The ease of maintenance adds to its appeal.
The Sierra International Shift Cover Gasket has definitely exceeded my expectations. It has provided a reliable and leak-free seal, ensuring smooth and consistent shifting performance, giving me the confidence to enjoy my time on the water without worrying about potential drive issues.
