Let’s Dive into Sierra International Tab Washer
The Sierra International Tab Washer is a seemingly simple, yet critical component in marine engine maintenance. Made by Sierra International, this tab washer is designed to secure various nuts and bolts, preventing loosening due to vibration, a common issue in marine environments. What sets this particular tab washer apart is its broad compatibility, fitting a range of engine brands and models, from Mercury/Mariner to Honda, Chrysler/Force/US Marine, and Mercruiser.
What led me to explore the Sierra International Tab Washer was a persistent problem with a loosening lower unit bolt on my older Mercury outboard. I tried thread locker, but the constant exposure to saltwater and vibration eventually overcame it. I was looking for a more mechanical and reliable solution, and tab washers kept coming up in discussions with other boaters.
My initial impression upon receiving the Sierra International Tab Washer was its robust construction. It’s a simple piece, but the metal felt durable and properly tempered, not flimsy or easily bent. The edges were clean, and the tabs seemed precisely cut, promising a good fit and secure locking.
I considered a few other tab washers from different manufacturers, but the Sierra International Tab Washer’s broad compatibility and positive online reviews swayed me. Some of the generic options seemed cheaper in quality, and I didn’t want to risk using an inferior part on my engine. This washer has a high compatibility across multiple brands.
Excited is probably an overstatement for a tab washer, but I was certainly optimistic. I hoped it would solve my recurring problem and provide peace of mind knowing that my lower unit bolts were securely fastened.
Real-World Testing: Putting Sierra International Tab Washer to the Test
First Use Experience
I tested the Sierra International Tab Washer during a routine lower unit oil change on my Mercury 40hp outboard. I installed it on the drain and fill plugs. The installation was straightforward; the washer fit perfectly over the plug and against the lower unit housing.
The marine environment presented a rigorous testing ground with constant exposure to saltwater spray and engine vibrations. After tightening the plug, I bent the tabs of the washer against the flats of the plug, effectively locking it in place. Everything remained tight.
The Sierra International Tab Washer was easy to use, even for someone with minimal mechanical experience. The tabs were pliable enough to bend easily with a pair of pliers but sturdy enough to hold their shape and provide a secure lock. I didn’t require a lot of time.
There were no immediate issues or surprises. The washer did exactly what it was supposed to do: secured the plug and prevented it from loosening.
Extended Use & Reliability
After several weeks of use, including multiple trips out on the water, the Sierra International Tab Washer continued to perform flawlessly. The bolts remained securely fastened. There was no leakage or sign of loosening.
The Sierra International Tab Washer shows no signs of wear or corrosion. It still looks as good as new.
Maintenance of the Sierra International Tab Washer is virtually nonexistent. If the washer gets greasy, it can simply be wiped clean with a rag.
In previous attempts to secure the lower unit bolts, I relied solely on thread locker. However, I found that the Sierra International Tab Washer has been a more reliable and effective solution.
