First Impressions of Sierra International 185873 Stator And Kit
The Sierra International 185873 Stator And Kit is a crucial component for maintaining the reliable performance of Mercury outboard engines, specifically the 100, 115, and 125 HP models. Manufactured by Sierra International, a well-known name in aftermarket marine parts, this kit aims to provide a direct replacement for worn or failing original equipment manufacturer (OEM) stators, ensuring the continued smooth operation of your boat. Its interchangeable compatibility with Chrysler and Mallory part numbers suggests broad usability, making it a seemingly versatile solution for various marine engine needs.
My journey to this product began with a nagging issue: inconsistent engine performance on my 1998 Mercury 115 HP outboard. The engine would occasionally sputter and stall, particularly at lower RPMs, pointing towards potential ignition system problems. After consulting with several marine mechanics and researching online forums, the stator emerged as a likely culprit, leading me to consider the Sierra International 185873 Stator And Kit as a potential solution.
Upon unboxing, the Sierra International 185873 Stator And Kit presented a solid first impression. The components appeared well-made, with clean wiring and sturdy construction. The weight felt appropriate, suggesting quality materials were used in its manufacture.
Compared to other aftermarket stators I considered, such as those from CDI Electronics, the Sierra International kit stood out due to its reputation for reliability and precise fitment. While CDI offered a slightly lower price point, the consistent positive feedback surrounding Sierra International’s products swayed my decision, prioritizing long-term performance over initial cost savings. My initial impression was one of cautious optimism; hoping this kit would finally resolve my engine’s persistent issues.
Real-World Testing: Putting Sierra International 185873 Stator And Kit to the Test
First Use Experience
The true test of the Sierra International 185873 Stator And Kit came during a weekend fishing trip to Lake Okeechobee, Florida. Installation required moderate mechanical skill, taking approximately two hours with standard tools. The instructions, although somewhat generic, were sufficient for a seasoned DIYer.
The engine fired up immediately after installation and ran noticeably smoother, particularly at idle. Testing involved several hours of trolling, running at various speeds, and repeated starts and stops. The Sierra International 185873 Stator And Kit performed flawlessly in the warm, humid conditions, showing none of the previous sputtering or stalling issues.
Extended Use & Reliability
After three months of regular use, including numerous fishing trips and recreational boating excursions, the Sierra International 185873 Stator And Kit continues to perform reliably. There are no signs of wear and tear on the stator itself. Periodic visual inspections have revealed no cracking or damage to the wiring insulation.
Maintenance has been minimal, primarily involving occasional cleaning of the engine compartment to prevent corrosion. This replacement outperformed the original stator, which had begun to fail prematurely after years of faithful service. It provided consistent ignition performance and resolved the intermittent engine problems I was experiencing, restoring confidence in my boat’s reliability.
