First Impressions of Sierra International 1899144 Yamaha Mixing Cover Gasket Replaces 6E7 14227 00
The Sierra International 1899144 Yamaha Mixing Cover Gasket Replaces 6E7 14227 00 might seem like a small, insignificant part, but to anyone who’s ever wrestled with a sputtering outboard motor, a quality gasket is pure gold. This particular gasket, manufactured by Sierra International, is designed as a direct replacement for Yamaha part number 6E7-14227-00, fitting 9.9 HP and 15 HP Yamaha models from 1984 to 1995. It’s a seemingly simple component that plays a crucial role in the proper function of your engine, ensuring a tight seal and preventing leaks that can lead to all sorts of performance issues.
My own journey to this gasket started with a frustratingly common problem: a small, but persistent fuel leak around the mixing cover of my trusty old Yamaha 9.9. The engine ran rough, fuel economy was down, and the smell of unburnt gas was a constant annoyance. After a bit of troubleshooting, it became clear that the original gasket had hardened and cracked over time, losing its ability to properly seal.
Upon receiving the Sierra International 1899144 Yamaha Mixing Cover Gasket, my initial impression was positive. The material felt robust and pliable, a stark contrast to the brittle remains of the original. While I didn’t have other replacement gaskets on hand for a direct comparison, I immediately appreciated that Sierra International claims their product meets or exceeds the original equipment standards. My excitement was tempered with cautious optimism; the true test would be in the installation and subsequent performance.
Real-World Testing: Putting Sierra International 1899144 Yamaha Mixing Cover Gasket Replaces 6E7 14227 00 to the Test
First Use Experience
The real test came on a blustery Saturday morning on Lake Serenity. I replaced the cracked and worn gasket with the Sierra International 1899144 Yamaha Mixing Cover Gasket. Installation was straightforward, as expected, but it’s crucial to ensure the mating surfaces are clean and free of debris.
The reassembled outboard fired up on the second pull, which was already an improvement. I idled for several minutes, carefully watching for any signs of leakage. There was absolutely no sign of leaking. Under load on the water, the engine responded crisply, and the telltale fuel smell was absent. The mixing cover stayed dry during varying RPM’s.
Extended Use & Reliability
Several weeks and numerous fishing trips later, the Sierra International 1899144 Yamaha Mixing Cover Gasket continues to perform flawlessly. There have been no new leaks, and the engine runs as smoothly as it did when new. I’ve run the boat in both calm and choppy conditions, as well as under varying temperature conditions and the gasket is performing great.
Inspection after several trips reveals no visible signs of wear or degradation on the gasket. Regular maintenance involves simply wiping down the engine after use, ensuring that no fuel or debris accumulates around the mixing cover area. Based on my experience, it noticeably outperforms the old, degraded original.
