First Impressions of Sierra International 1860918 Engine Base Gasket
The Sierra International 1860918 Engine Base Gasket might not be the sexiest piece of gear I’ve ever laid hands on, but in the world of outboard motors, a reliable gasket is pure gold. Manufactured by Sierra International, this gasket promises optimal performance and reliability for specific Mercury and Nissan/Tohatsu engines. Having wrestled with leaky engine bases more times than I care to admit, a high-quality gasket is a welcome sight.
My old Mercury 9.9 was starting to weep oil from the base, leaving an unsightly slick in the water. Finding a compatible replacement was crucial to keep my engine running smoothly and prevent further damage. The Sierra International 1860918 Engine Base Gasket seemed like a perfect fit based on the engine compatibility listed.
Upon unboxing, the gasket appeared well-made, with clean edges and consistent thickness. It felt like a quality product. I’ve used aftermarket gaskets before, some of which felt flimsy and ill-fitting. This gasket looked noticeably better than some of the cheaper options I’ve seen.
Compared to a generic gasket I had lying around, the Sierra International version seemed denser and more precisely cut. The generic one felt a bit too flexible, which never inspires confidence. I chose the Sierra International 1860918 Engine Base Gasket over other brands based on Sierra International’s reputation for quality and the specific fitment for my engine.
My initial impression was positive and hopeful. If it performs as well as it looks, this gasket will be a lifesaver. I was cautiously optimistic, eager to get it installed and back on the water.
Real-World Testing: Putting Sierra International 1860918 Engine Base Gasket to the Test
First Use Experience
I installed the Sierra International 1860918 Engine Base Gasket on my Mercury 9.9 outboard motor at my lakeside cabin. The engine base was cleaned thoroughly before installation. I followed the engine manufacturer’s torque specifications meticulously.
During initial testing, the engine ran smoothly, and there were no immediate signs of leaks. I ran the engine for about an hour at varying speeds. No oil slick developed on the water, which was a huge relief.
Installation was straightforward, but aligning everything perfectly took a bit of patience. The gasket seemed to compress evenly as the bolts were tightened. No unexpected problems arose during the installation or first run.

After several weeks of use, the Sierra International 1860918 Engine Base Gasket continues to perform flawlessly. I’ve taken the boat out multiple times for fishing trips. It has endured both short runs and extended periods of high-speed cruising.
The gasket shows no signs of wear or leaks, even after being subjected to vibration and varying temperatures. The engine base remains clean and dry. Regular visual inspections have revealed no issues with the gasket’s sealing capability.
The Sierra International 1860918 Engine Base Gasket has significantly outperformed the previous, failing gasket and several cheaper alternatives I’ve used in the past.
