I had considered other aftermarket options, but the Sierra International name and the interchangeability with the Mercruiser OEM part number (32-38377) gave me the confidence to choose this product.
My initial excitement was tempered with the anticipation of a potentially messy and complicated repair. However, knowing that a quality component was going in to fix the problem made all the difference. I was hoping this replacement tube would restore the smooth shifting I had been missing.
