Sierra International 185442 Ignition Coil Review

First Impressions of Sierra International 185442 Ignition Coil

The Sierra International 185442 Ignition Coil arrived, promising to be the solution to a sputtering engine that had been plaguing my vintage ski boat for weeks. Sierra International isn’t a name synonymous with high-performance, flashy upgrades, but rather a dependable provider of essential marine engine parts. The key selling point advertised was its direct compatibility with GM V-8 engines using Delco HEI ignitions, excluding the trickier MPI engines.

My boat, a ’78 Chris-Craft with a classic 350 small block, had been acting up something fierce. The symptoms pointed directly to a failing ignition coil: hesitant starts, a noticeable loss of power at higher RPMs, and the occasional backfire that made everyone on board jump. I had limped through the last few outings, knowing a fix was imminent.

The Sierra International 185442 Ignition Coil came packaged in a plain, no-nonsense cardboard box. There were no flashy graphics, just the part number and Sierra International logo. Upon opening, I found the coil securely wrapped in plastic. My initial impression was positive; it looked like a robust, well-made unit. It had a reassuring weight and the terminals seemed sturdy. I picked it over a generic brand because I needed reliability, and Sierra International has a reputation for just that.

Compared to the old, cracked and corroded coil I removed from the engine, the Sierra International 185442 Ignition Coil was a breath of fresh air. It felt solid and gave me the impression it would last for a good few seasons. Initially, I was relieved and cautiously optimistic, hoping this would finally resolve the engine troubles and get me back on the water without any hiccups.

Real-World Testing: Putting Sierra International 185442 Ignition Coil to the Test

First Use Experience

I tested the Sierra International 185442 Ignition Coil on my ’78 Chris-Craft, launching from a local lake known for its choppy conditions and heavy recreational use. The weather was typical for late summer: humid, with a slight breeze and scattered showers predicted later in the day. I installed the coil easily, following the service manual for my engine. The connections were straightforward and the coil fit perfectly in the original mounting location.

The moment of truth came when I turned the key. The engine roared to life almost immediately, with a crisp, clean sound that had been missing for weeks. Out on the water, the difference was remarkable. The boat accelerated smoothly, reaching top speed without hesitation. The power loss I had been experiencing was completely gone. Even in the choppy water, the engine performed flawlessly, and after a couple of hours on the lake, there were no issues.

Extended Use & Reliability

After several weeks of use, the Sierra International 185442 Ignition Coil continues to deliver reliable performance. I’ve put about 30 hours on the engine since the install, with a mix of cruising, water skiing, and tubing. The engine starts quickly every time, even after sitting for a week or more.

There are no signs of wear or tear on the coil itself. The terminals are still clean and tight. The coil doesn’t get excessively hot, even after extended periods of running at high RPMs. Regular wipe-downs with a damp cloth are all it takes to keep it clean and looking like new. The Sierra International 185442 Ignition Coil has far exceeded my expectations.
