Hands-On with the Sierra International 185798 Trigger Assembly Mercury 6 Cyl.
The Sierra International 185798 Trigger Assembly Mercury 6 Cyl. isn’t exactly the type of gear I usually review. I’m more accustomed to tactical knives, durable packs, and weatherproof clothing. However, a buddy of mine, a seasoned marine mechanic, was struggling with a finicky Mercury outboard on his vintage fishing boat, and this trigger assembly was the suggested solution. It promised to be a direct replacement for several older Mercury part numbers, potentially saving him a fortune in labor costs.
What drew me to this particular trigger assembly was the claim of meeting or exceeding original equipment quality. This claim is crucial in the marine environment where reliability is paramount. Out on the water, a faulty trigger assembly can quickly turn a pleasant fishing trip into a dangerous situation.
Unboxing the Sierra International 185798 Trigger Assembly Mercury 6 Cyl. revealed a seemingly well-constructed unit. The components looked clean, and the wiring appeared properly insulated. My initial thought was that Sierra International seemed to have paid attention to detail, but the real test would be in its installation and performance.
Compared to other aftermarket trigger assemblies, this one stood out due to its compatibility with multiple Mercury part numbers (96455A9, 96455A6, 68162A5, 68162A1, 68162A8). This broader compatibility makes it a more versatile option. I chose this over potentially cheaper, less-established brands due to Sierra International’s reputation in the marine parts industry.
I was cautiously optimistic. Aftermarket marine parts can be a mixed bag. While the initial impression was positive, the real determinant would be its performance under the demanding conditions of marine use.
Real-World Testing: Putting Sierra International 185798 Trigger Assembly Mercury 6 Cyl. to the Test
First Use Experience
The real test took place at my buddy’s dock. It was a typical humid summer day, the kind that makes working on an engine less than pleasant. We installed the Sierra International 185798 Trigger Assembly Mercury 6 Cyl. on his 1978 Mercury 850 outboard.
The installation process itself was straightforward, thanks in part to the relatively simple design of the older Mercury engines. However, proper alignment was crucial. After installation, the engine fired up after a few cranks, a significant improvement over its previous erratic behavior. The throttle response was noticeably smoother and more consistent.
There weren’t any immediate issues, but the true measure of its worth would come after several hours of use on the water.
Extended Use & Reliability
Over the next few months, my buddy put the outboard and the new trigger assembly through its paces. He used it for fishing trips, recreational boating, and even some light towing. The Sierra International 185798 Trigger Assembly Mercury 6 Cyl. performed admirably.
There were no signs of degradation or malfunction, even after prolonged exposure to saltwater and the constant vibrations of the engine. The wiring remained secure, and the unit continued to deliver consistent performance. Regular visual inspections and occasional cleaning with a marine-grade corrosion inhibitor have been the only maintenance required.
Compared to his previous experiences with aftermarket parts, this trigger assembly has far exceeded expectations. He had previously dealt with parts that failed prematurely or caused more problems than they solved. The Sierra International unit, however, proved to be a reliable and cost-effective solution.
