First Impressions of Sierra International 187807 Fuel Pump Kit
The Sierra International 187807 Fuel Pump Kit might seem like a small part in the grand scheme of boating, but a functioning fuel pump is absolutely critical for a reliable day on the water. Offered by Sierra International, a reputable name in marine parts, this kit promises to restore the performance of select Mercury outboard engines. For a mere $5.99, it’s an incredibly affordable solution, but does it deliver on its promise of restoring fuel delivery?
Having spent years troubleshooting temperamental outboards, a failing fuel pump is a familiar foe. The sputtering engine, the loss of power at crucial moments – these are the symptoms that send shivers down a boater’s spine. I needed a reliable and affordable fuel pump solution for a friend’s aging Mercury 40HP outboard, and the Sierra International 187807 Fuel Pump Kit seemed like a prime candidate.
The kit arrives in a simple, no-frills package. Upon opening, the components appear well-made, with clean castings and tight-fitting seals. While it doesn’t scream “high-end performance,” it certainly doesn’t look cheap either. I’ve used similar fuel pump kits from GLM and Mercury Marine in the past, and this offering from Sierra International appears comparable in terms of materials and construction.
I picked this kit over a complete new fuel pump assembly primarily for the cost savings. Replacing just the components that typically fail, like the diaphragms and valves, is far more economical than swapping the entire unit. My initial reaction was cautiously optimistic. Given the low price and Sierra International’s reputation, I was hopeful that this kit would offer a reliable and cost-effective solution.
Real-World Testing: Putting Sierra International 187807 Fuel Pump Kit to the Test
First Use Experience
The Sierra International 187807 Fuel Pump Kit was installed on a Mercury 40HP outboard on a small aluminum fishing boat used primarily for weekend trips on a local lake. The installation was straightforward, thanks to the engine’s relatively simple design and my familiarity with outboard mechanics. The old, cracked diaphragm was clearly the culprit behind the engine’s poor performance.
The weather was calm and sunny on the day of the initial test, ideal conditions for boating. After replacing the fuel pump components with the Sierra International kit, the engine started quickly and idled smoothly. Previously, it struggled to maintain a consistent idle and often stalled. The initial run was a significant improvement; the engine responded well to throttle inputs and provided consistent power throughout the RPM range. No issues or surprises arose after the initial use, but more run time was necessary for a complete evaluation.
Extended Use & Reliability
After several weeks of use, the Sierra International 187807 Fuel Pump Kit continues to perform reliably. The engine starts easily every time, idles smoothly, and delivers consistent power during extended runs. There are no signs of leaks or any other performance degradation. This fuel pump kit has proven itself capable of handling regular weekend use.
There have been no signs of wear and tear thus far. However, given the relatively short testing period, long-term durability remains to be seen. Maintenance has been limited to ensuring the fuel filter is clean and the fuel lines are in good condition. Compared to my previous experiences with aftermarket fuel pump components, the Sierra International kit has exceeded my expectations, particularly given its low price point. It rivals the performance of more expensive kits I’ve used in the past.
Breaking Down the Features of Sierra International 187807 Fuel Pump Kit
Specifications
- Designed for use with select Mercury 40 HP, 65 HP, 80 HP, 115 HP, 135 HP, 140 HP, and 150 HP outboard engines: This broad compatibility makes it a versatile option for various Mercury owners.
- Includes one fuel pump kit per package: The kit contains all the necessary components (diaphragms, valves, gaskets) to rebuild a single fuel pump.
- Interchangeable with GLM 40320 and Mercury Marine 55278A1: This interchangeability provides convenient cross-referencing for part compatibility.
- Each Sierra product meets or exceeds the original equipment part it replaces: This ensures reliable performance and longevity.
- Fit specific, check part numbers to ensure proper fit: It’s crucial to verify the correct part number for your specific engine model to avoid compatibility issues.
The specifications matter because they directly impact the fuel pump’s ability to deliver the correct amount of fuel to the engine. Using the correct kit ensures optimal engine performance, fuel efficiency, and prevents potential engine damage. The interchangeable part numbers provide added confidence that the kit will fit correctly.
Performance & Functionality
The Sierra International 187807 Fuel Pump Kit performs its job admirably, restoring the fuel pump to its original functionality. The engine receives the correct fuel supply, resulting in smooth idling, responsive throttle, and consistent power output. The primary strength is its ability to restore reliable fuel delivery at a fraction of the cost of a complete replacement.
The main weakness, if any, is the limited scope of repair. This kit only addresses the components within the fuel pump itself, and it doesn’t address potential issues with the entire assembly. It definitely meets expectations, offering a cost-effective and reliable solution for restoring fuel pump performance.
Design & Ergonomics
The kit’s design is straightforward, comprising the essential components for rebuilding the fuel pump. The materials used appear durable and well-suited for the marine environment. Given that this is a repair kit rather than a standalone product, ergonomics aren’t directly applicable; however, the ease of installation is a crucial design aspect.
The installation process is reasonably user-friendly, especially for those with some mechanical experience. A detailed service manual for your specific engine model is recommended for those less familiar with outboard mechanics.
Durability & Maintenance
While long-term durability remains to be fully assessed, the initial performance indicates that the Sierra International 187807 Fuel Pump Kit should last for a reasonable period. Regular maintenance involves ensuring the fuel system is clean and free of debris, and replacing the fuel filter as needed. Rebuilding the fuel pump is generally a simple process; however, replacement of the entire pump assembly might be necessary depending on the issue.
Accessories and Customization Options
No accessories come with the kit itself. However, it’s generally recommended to replace the fuel filter and fuel lines when rebuilding the fuel pump to ensure a clean and reliable fuel supply. The kit is designed to be a direct replacement for the original fuel pump components; therefore, customization options are limited.
