The real test began during the engine rebuild itself. Replacing a crankshaft bearing is not a task for the faint of heart. It requires precision and attention to detail. The Sierra International Lower Crankshaft Bearing fit perfectly into the engine block.

Once the engine was reassembled, I took my boat out for a test run on a local lake. The vibration that had plagued my previous trips was gone. The engine ran smoothly and quietly. I was able to put the engine through its paces.

Extended Use & Reliability

After several weeks of use, including a few offshore fishing trips, the Sierra International Lower Crankshaft Bearing continues to perform flawlessly. There are no new vibrations. The engine’s performance remains consistent.

So far, I haven’t noticed any signs of wear and tear on the bearing itself, although that requires a more involved inspection. Regular oil changes and proper engine maintenance are crucial. These will ensure the bearing has a long lifespan. This Sierra International bearing is performing better than I expected, given my past experiences with aftermarket parts.
