Sierra International 1823169 Washer Review

The Sierra International 1823169 Washer: First Use to Final Thoughts

The Sierra International 1823169 Washer might seem like an insignificant part, but in the world of marine engines, a correctly sized and functioning washer is critical for proper operation and longevity. Manufactured by Sierra International, this seemingly simple component plays a crucial role in ensuring smooth operation within Mercruiser/Mercury stern drive systems. This review isn’t about the thrill of the open water but rather the critical importance of small parts in ensuring you stay on the open water.

My personal boat, a 1999 Bayliner Capri with a Mercruiser Alpha One Gen II drive, started exhibiting some unusual vibrations at higher RPMs. After some careful troubleshooting, a mechanic pinpointed excessive play within the drive unit attributed to worn washers. The Sierra International 1823169 Washer was selected as a replacement. I needed a reliable part that met or exceeded OEM specifications to restore my boat’s performance and reliability.

Unboxing the Sierra International 1823169 Washer, there wasn’t much to see beyond a simple, precisely machined metal washer. However, the quality of the metal and the exactness of the dimensions were immediately apparent. Compared to generic washers from a local hardware store, this part exuded a level of precision suggesting it was designed for demanding marine applications.

Generic washers are a dime a dozen, but when dealing with the complex mechanisms of a stern drive, reliability is paramount. I chose the Sierra International 1823169 Washer over GLM 30030, Mercruiser Stern Drive 12-77674, or Mercury Marine 12-77674 because of Sierra International’s reputation for quality aftermarket marine parts and its specific compatibility with my Gen II drive. I wanted to be back on the water, and I wasn’t going to compromise on a potential failure point.

My first impression was one of cautious optimism. I was eager to install the washer and see if it resolved the vibration issue. The real test would come on the water, under load, where any weakness would quickly become apparent.

Real-World Testing: Putting Sierra International 1823169 Washer to the Test

First Use Experience

The installation was performed by a certified marine mechanic during a scheduled maintenance. He confirmed the old washer was indeed worn, contributing to the play in the drive unit. Once the Sierra International 1823169 Washer was installed, the initial sea trial was conducted in relatively calm conditions on Lake Michigan.

The difference was immediately noticeable. The vibration that had plagued my boat at higher RPMs was significantly reduced. The engine ran smoother, and the boat felt more responsive. While not a dramatic, visual upgrade, the improvement in performance was undeniable.

There were no surprises. The Sierra International 1823169 Washer performed exactly as expected, restoring the proper tolerances within the stern drive.

After a full season of boating, including numerous trips on Lake Michigan in varying conditions (from calm waters to choppy waves), the Sierra International 1823169 Washer has held up flawlessly. There are no signs of premature wear or any recurrence of the vibration issue. The drive unit continues to operate smoothly and efficiently.

There’s minimal maintenance required for a washer, but regular inspection of the stern drive as part of routine servicing is essential. The washer has shown no signs of corrosion or degradation, indicating the quality of the materials used.

Compared to my previous experiences with aftermarket parts of dubious origin, the Sierra International 1823169 Washer has far exceeded expectations. Its reliability has given me confidence in the overall health and performance of my boat’s stern drive.
