First Impressions of Sierra International 189076 Collar For Yamaha & Mercury 2 Stroke & 4 Stroke Engines
Having spent countless hours troubleshooting and repairing outboard motors in every imaginable condition, from saltwater corrosion battles on the Gulf Coast to high-altitude tuning on remote mountain lakes, I’ve learned that even the smallest parts can make or break a day on the water. That’s why when I saw the Sierra International 189076 Collar For Yamaha & Mercury 2 Stroke & 4 Stroke Engines, I immediately knew it deserved a closer look. This unassuming little collar plays a critical role in maintaining proper engine function, and a quality replacement can be the difference between smooth sailing and a frustrating tow back to shore.
My own aging Yamaha 2-stroke, a reliable workhorse that’s seen more sunrises than most boats, had recently developed a subtle vibration at higher RPMs. After checking the usual suspects – prop, fuel lines, spark plugs – my experienced eye landed on the collar connecting the shift shaft. It showed signs of wear and potential slippage. I needed a replacement, and I needed it fast. I looked at OEM parts, but the price point made me search for a reliable alternative. The Sierra International 189076 Collar promised compatibility with both Yamaha and Mercury engines, along with interchangeability with other reputable brands like Mallory, making it an attractive option.
The Sierra International collar arrived promptly, packaged simply but securely. My first impression was positive. The collar felt solid and well-machined. Its weight and finish exuded quality. Compared to the worn, slightly corroded collar I removed from my Yamaha, the Sierra International 189076 Collar was a breath of fresh air. I had initially considered a Mercury Marine OEM replacement, and a generic aftermarket option from a local shop. I chose the Sierra International part because of the company’s reputation for quality aftermarket marine parts and the broader compatibility.
I was optimistic but realistic. Aftermarket parts can sometimes be a gamble. However, Sierra International has consistently delivered reliable alternatives to OEM parts, and I was hopeful that this collar would be no exception. Only real-world testing would tell if this little component could restore my engine’s smooth operation.

First Use Experience
The first test of the Sierra International 189076 Collar came during a planned fishing trip on a local lake known for its largemouth bass. Installation was straightforward; the collar slipped onto the shift shaft with a snug, precise fit. Once everything was reassembled and properly torqued, I fired up the engine. Immediately, I noticed a difference. The idle was smoother, and the subtle vibration that had plagued me was noticeably reduced.
Out on the water, I gradually increased the RPMs. The engine responded smoothly, with none of the hesitation or vibration I had experienced before. I ran it through its full range, from trolling speeds to full throttle, and the Sierra International 189076 Collar performed flawlessly.

I’ve put my boat through its paces in various conditions. I’ve handled choppy waters and long runs at full throttle. The collar shows no signs of wear or slippage. The engine maintains its smooth, reliable operation.
Maintenance has been minimal. I’ve simply inspected the collar during routine engine checks, ensuring it remains properly seated and free from excessive corrosion. A quick wipe-down with marine-grade grease is all that’s been needed to keep it in top condition. This collar has outperformed my expectations. It provides a cost-effective and reliable solution for a common outboard motor issue. I’ve used other aftermarket collars in the past that quickly degraded or failed under stress.
