My own experience with older Mercury outboards has often involved grappling with fuel delivery issues, from sputtering engines to complete breakdowns. A reliable fuel pump is paramount. After dealing with a frustrating experience where my vintage Mercury 65 HP stalled repeatedly during a fishing trip, I decided to proactively address the fuel system and stumbled upon this kit.

Real-World Testing: Putting Sierra International 187804 Fuel Pump Kit to the Test
First Use Experience
The first test of the Sierra International 187804 Fuel Pump Kit occurred during a weekend fishing trip on a local lake. Installation took place in my garage. With basic hand tools and the old pump as a reference, I replaced the diaphragms and gaskets.
The engine started after a few priming pulls. The initial idle was noticeably smoother. Previously, the motor struggled to maintain a constant speed at low RPMs, threatening to stall if I did not feather the throttle. After warming it up, I took the boat out on the water for testing under different loads. The engine responded promptly to throttle inputs and did not exhibit any of the previous hesitation or sputtering issues, making it easier to maneuver around docks and trolling spots.
Extended Use & Reliability
After several weeks of regular use, the Sierra International 187804 Fuel Pump Kit has performed admirably. I have accumulated approximately 30 hours of run time on my outboard since the installation. The engine continues to start easily and runs smoothly throughout the RPM range.
I regularly inspect the engine for any signs of fuel leaks or other issues. So far, there have been none. Compared to my previous experiences with other aftermarket fuel pump components, the Sierra International kit seems to be holding up well. I anticipate that with proper fuel maintenance and occasional cleaning, this kit will provide reliable performance for a long time.
