Real-World Testing: Putting Sierra International 1871336 Impeller To Plate O Ring For Johnson/Evinrude, OMC/Brp Outboards to the Test
First Use Experience
I tested the Sierra International 1871336 during a water pump impeller replacement on my Johnson 150HP outboard before the start of the fishing season. The installation was straightforward, and the O-ring seated perfectly between the impeller plate and the water pump housing. It created a snug fit, essential for preventing water leaks.
The first few hours of running the engine after the replacement were smooth, with no signs of overheating or reduced water flow. The true test came during a weekend-long fishing trip in choppy conditions and varying engine speeds. After a full day on the water, I checked the engine temperature, and it remained within the normal operating range. This suggested that the Sierra International O-ring was performing its job effectively, maintaining proper water circulation even under demanding conditions.
Extended Use & Reliability
After several months of use and numerous fishing trips, the Sierra International 1871336 continues to perform flawlessly. There are no signs of degradation or leaks around the water pump housing. The engine temperature remains consistently within the normal range, providing confidence in the cooling system’s reliability.
Periodically, I inspect the water pump area as part of routine maintenance, and the O-ring still appears to be in good condition, retaining its shape and pliability. This is a significant improvement compared to previous generic O-rings I’ve used, which tended to harden and crack after a relatively short period of time. The Sierra International 1871336 has exceeded my expectations. Its durability and reliability have proven to be well worth the slightly higher cost compared to generic alternatives.
