Sierra International Shift Housing Gasket Review

Let’s Dive into Sierra International Shift Housing Gasket

The Sierra International Shift Housing Gasket might not be the sexiest piece of gear, but it’s absolutely critical for keeping your Johnson or Evinrude outboard running smoothly. Made by Sierra International, these gaskets are small but mighty, preventing leaks that can cause major headaches on the water. I first encountered the need for these little guys when an older Evinrude I inherited started exhibiting some concerning shift issues.

The leaking fluid was a mess, and the shifting felt sloppy. After a bit of research, it became clear that the shift housing gasket was the likely culprit. While there are certainly other aftermarket gasket options, the Sierra International reputation for quality and precise fit made me lean towards their product. My initial impression upon receiving the gaskets was positive; they appeared well-made with clean edges and a pliable material.

Compared to generic gasket sets, the Sierra International Shift Housing Gasket seemed to be of superior quality and more precision manufacturing. I also considered GLM gaskets, but based on online reviews highlighting consistent dimensions and durability for Sierra International, I decided to go with them. My excitement level was moderate, as it’s just a gasket, but the prospect of solving my outboard’s shifting issues definitely put a spring in my step.

Real-World Testing: Putting Sierra International Shift Housing Gasket to the Test

First Use Experience

My first test came during the repair of my ’70s Evinrude 65 HP outboard, which I use for weekend fishing trips on a nearby lake. I installed the Sierra International Shift Housing Gasket during a complete lower unit service. The installation process went smoothly, the gasket fitting perfectly into the shift housing without any need for trimming or modification.

The gasket sealed flawlessly right away. I then ran the motor both in a test tank and on the water, checking for any signs of leakage around the shift shaft. No leaks, even after prolonged use. Shifting felt significantly smoother and more precise after the repair.

Extended Use & Reliability

After several months of regular use (approximately 20-30 hours on the water), the Sierra International Shift Housing Gasket continues to perform flawlessly. There are no signs of deterioration or leakage. The engine operates smoothly, and shifting remains precise.

Compared to previous gasket replacements I’ve attempted with cheaper alternatives, this has been a night-and-day difference; previous repairs required re-torquing bolts and constant monitoring. With the Sierra International gasket, I installed it and forgot about it, which is exactly what you want in a critical sealing component.
