Sierra International 187352 Fuel Pump Review

First Impressions of Sierra International 187352 Fuel Pump

The Sierra International 187352 Fuel Pump is not exactly the kind of product that sets your pulse racing, unlike a new rifle or a high-end optic. However, a reliable fuel pump is absolutely critical for any boater who wants to avoid getting stranded miles from shore. Sierra International is a well-known name in marine parts, and the 18-7352 model, designed as a replacement for various Evinrude/Johnson outboards, promises a blend of dependability and compatibility.

I was driven to purchase this pump after experiencing persistent fuel delivery issues on my vintage Johnson 70hp outboard. The original pump was sputtering and causing the engine to run rough, making fishing trips an exercise in frustration rather than relaxation. I needed a dependable replacement to avoid potentially dangerous situations on the water.

Upon receiving the Sierra International 187352 Fuel Pump, I was immediately impressed by its solid construction. The materials felt robust, and the machining appeared precise, hinting at a quality build. Compared to some cheaper aftermarket pumps I’ve seen, this one felt like a step up in terms of materials and construction. I considered a Mallory pump as well, but Sierra’s reputation and the direct interchangeability claims swayed my decision. My first impression was one of cautious optimism; I was hoping this pump would finally solve my fuel delivery problems.

Real-World Testing: Putting Sierra International 187352 Fuel Pump to the Test

First Use Experience

My initial test took place on Lake Lanier, a large reservoir known for its sometimes-choppy conditions. I installed the Sierra International 187352 Fuel Pump, which was a straightforward process thanks to its designed interchangeability. The moment of truth came when I turned the key; the engine sprang to life with a vigor it hadn’t shown in months.

Out on the water, the difference was immediately noticeable. The engine idled smoothly and responded crisply to throttle inputs. Previously, the engine would hesitate and sometimes stall during acceleration, especially in choppy water. This time, however, it powered through the waves without a hiccup. After an hour of running at various speeds, the pump performed flawlessly.

Extended Use & Reliability

Now, several months and countless fishing trips later, the Sierra International 187352 Fuel Pump continues to perform admirably. There are no signs of leaks or deterioration, even after prolonged exposure to sun and saltwater spray. I always flush the engine after each use with fresh water, but the pump itself requires no special maintenance beyond that.

Compared to my previous experiences with aftermarket fuel pumps, the Sierra International model has been a revelation. It consistently delivers the fuel needed to keep the engine running smoothly and reliably. I would definitely recommend this fuel pump over cheaper alternatives that I’ve tested and had to replace multiple times in one season.
