Sierra International 185303 185303 Contact Set Review

First Impressions of Sierra International 185303 185303 Contact Set

The Sierra International 185303 185303 Contact Set might not sound like the sexiest piece of gear, but for anyone running older Ford or GM engines with Prestolite ignition systems, it’s a vital component. Without a functioning contact set, your boat or classic car is going nowhere fast. It’s a relatively inexpensive part that can cause a major headache if it fails, so reliability is paramount.

My old Chris-Craft’s engine started sputtering something awful a few weeks ago. I traced the problem back to a worn-out contact set, which was causing inconsistent spark.

When the Sierra International 185303 185303 Contact Set arrived, my initial thought was, “Finally, a solution!”. The set looks well-made, the contacts are clean, and the construction appears solid. Compared to some generic, no-name contact sets I’ve seen online, this one definitely inspires more confidence.

I’d considered a few other brands like Mallory and CDI, but Sierra International has a long-standing reputation for quality marine parts. Plus, the price was right.

Initially, I was just relieved to have a replacement part in hand. Now I just hope the installation is as straightforward as it seems.

Real-World Testing: Putting Sierra International 185303 185303 Contact Set to the Test

First Use Experience

My primary testing ground for the Sierra International 185303 185303 Contact Set was on my 1972 Chris-Craft, powered by a trusty old Ford 302 with a Prestolite ignition. The installation was relatively simple, aided by the fact that I’ve tinkered with this engine for years. Once installed, the engine fired up almost immediately, a vast improvement from the sputtering mess I was dealing with previously.

I tested the boat on the lake under various conditions. During the initial run, the engine performed flawlessly. No misfires, no hesitation, just smooth, consistent power.

The engine started and ran perfectly, with no apparent issues and was truly a pleasant surprise.

Extended Use & Reliability

After several weeks of regular use, the Sierra International 185303 185303 Contact Set continues to perform admirably. I’ve put roughly 50 hours on the engine since installation, and there hasn’t been a single hiccup. No signs of premature wear or any degradation in performance.

Periodic checks of the contact points show minimal wear, suggesting the materials are holding up well. A little dab of distributor cam lube keeps things running smoothly. This is a standard maintenance practice, regardless of the brand of contact set.

Compared to the previous, no-name contact set that failed prematurely, the Sierra International 185303 185303 Contact Set is a clear winner in terms of reliability and longevity. It’s performing far beyond my initial expectations.
