First Impressions of Sierra International 185798 Trigger Assembly Mercury 6 Cyl.
As someone who’s spent over a decade elbow-deep in the guts of outdoor and tactical gear, I’ve seen my share of engine components, but the Sierra International 185798 Trigger Assembly Mercury 6 Cyl. immediately caught my attention. This isn’t a flashy gadget, but a crucial component for keeping those classic Mercury 6-cylinder outboards purring. My initial thought was, “Can this aftermarket part truly stand up to the rigors of marine use and match the reliability of the original?”
I was particularly interested in this trigger assembly because my own ’70s-era Mercury 850 needed some TLC. The old trigger was causing intermittent spark issues, making it a pain to get the boat running consistently. After comparing it to CDI Electronics’ equivalent and an OEM Mercury part (both pricier), I decided to give the Sierra International 185798 Trigger Assembly Mercury 6 Cyl. a shot. I was cautiously optimistic; hoping for a solid, reliable replacement that wouldn’t break the bank.
Unboxing the Sierra International 185798 Trigger Assembly Mercury 6 Cyl. revealed a well-packaged unit. The assembly felt substantial in hand, with clean wiring and robust-looking components. My initial impression was positive, leaning towards excitement, though the true test would be its performance out on the water.
Real-World Testing: Putting Sierra International 185798 Trigger Assembly Mercury 6 Cyl. to the Test
First Use Experience
I tested the Sierra International 185798 Trigger Assembly Mercury 6 Cyl. on my vintage Mercury 850 outboard, mounted on a 16-foot runabout. The initial sea trial took place on a moderately choppy lake, with air temperatures hovering around 70 degrees Fahrenheit. Installation was straightforward, thanks to clear instructions and a design closely mirroring the original part.
Right off the bat, the engine fired up with a responsiveness I hadn’t experienced in years. Throttle response was smooth and predictable; and there was no hesitation during acceleration. The real test came when I pushed the engine to higher RPMs; the Sierra International 185798 Trigger Assembly Mercury 6 Cyl. performed flawlessly.
Extended Use & Reliability
After three months of regular use (averaging 2-3 trips per week), the Sierra International 185798 Trigger Assembly Mercury 6 Cyl. continues to deliver consistent performance. I’ve taken the boat out in various conditions: calm waters, choppy seas, and even a couple of rainy days. The assembly has shown no signs of degradation or performance loss.
I regularly inspect the wiring and connections for corrosion; but so far, everything looks as good as new. Maintenance involves a simple spray of corrosion inhibitor on the terminals after each outing, and a more thorough cleaning once a month. Compared to the frustration of constantly tinkering with the old trigger, this Sierra International part has been a welcome relief. It has exceeded my initial expectations.
