Let’s Dive into Sierra International 185170 Ignition Coil
The Sierra International 185170 Ignition Coil is a crucial component for marine engines, responsible for providing the high-voltage spark needed to ignite the air-fuel mixture. Sierra International, a trusted name in marine parts, engineered this coil to meet or exceed OEM specifications, promising reliable performance and longevity. Having spent years troubleshooting and repairing marine engines, I’ve learned the hard way that a faulty ignition coil can turn a relaxing day on the water into a frustrating and potentially dangerous situation.
My own journey with this type of product began after experiencing intermittent engine stalling on my vintage outboard motor. The frustrating part was that it would start and run flawlessly for a while, then out of nowhere just cut off, leaving me dead in the water. It was time to diagnose and replace the ignition coil.
Upon receiving the Sierra International 185170 Ignition Coil, I immediately noted its solid construction and clean finish. The coil felt substantial in my hand, hinting at the quality of materials used. Compared to generic aftermarket coils I’ve seen, this one definitely looks and feels like a premium product.
Other similar ignition coils available include GLM 72060, Evinrude/Johnson 0583740, and Mallory 9-23104, but I chose the Sierra International 185170 Ignition Coil due to Sierra International’s reputation for quality and the part’s direct compatibility with my engine. Many cheaper options exist, but a coil failure far from shore isn’t worth the few dollars saved.
My first impression was one of relief and cautious optimism. I was excited to get the engine running reliably again, but also wary of potential installation issues or unforeseen problems. Having dealt with countless aftermarket parts, I knew that even a well-regarded brand could occasionally have a hiccup.
Real-World Testing: Putting Sierra International 185170 Ignition Coil to the Test
First Use Experience
I tested the Sierra International 185170 Ignition Coil on my 1978 Evinrude 85HP outboard. I installed it in my driveway, which took about 30 minutes using basic tools. The moment of truth came when I turned the key, and the engine sprang to life with a newfound eagerness.
The engine idled smoothly and responded instantly to throttle inputs. I took the boat out on the local lake, encountering choppy conditions with light rain. Throughout the day, the engine performed flawlessly, with no signs of the previous stalling issues.
The installation process was straightforward, thanks to the coil’s precise fit and the clear instructions provided. After years of struggling with difficult-to-install parts, this was a welcome change. No initial issues or surprises were encountered, which was a great sign of the coil’s build quality and compatibility.
Extended Use & Reliability
After several weeks of use, the Sierra International 185170 Ignition Coil continues to deliver consistent performance. The engine starts quickly every time, and I have experienced no further stalling incidents. I have about 40 hours of run time on the new coil.
Durability seems excellent. The coil shows no signs of wear or corrosion, despite exposure to saltwater spray and varying weather conditions.
Maintenance is minimal; I simply inspect the coil and its connections periodically for any signs of damage or corrosion. It outperforms the original coil and several cheaper aftermarket options I’ve tried in the past. This Sierra International product is far more reliable than previous attempts to fix the stalling issue.
