    Sierra Marine engine parts are designed to meet or exceed the OEM part they are intended to replace and they are backed by the SeaStar Solutions Two-Year Warranty—one of the best in the business.

    We offer a variety of O-rings, oil seals and seal kits for most engine applications on the water today—including MerCruiser, OMC, Johnson/Evinrude, Volvo and more.

    How to find the O-ring you need

    Many of the O-rings we offer fit multiple applications. Notice in the list below that in addition to Yamaha Outboard and Mallory applications, there are a variety of other engine applications for the O-rings offered here. O-rings can also be selected by inside diameter and width, which also appear in the table.

    The Sierra Engine Parts Selector

    If you do not see the O-ring (or other engine part) you need, please visit the Sierra Engine Parts Selector, where you can search by engine make, model, serial number or year of manufacture.
