Sierra 18-2045 Oil Seal for Volvo Penta Stern Drive, White

The Sierra 18-2045 is a marine oil seal engineered for Volvo Penta stern drive applications. This white, round seal is built to meet or exceed original equipment quality, giving boat owners a reliable replacement for maintaining a proper seal against oil leakage in the stern drive assembly. Sierra manufactures its seals to close tolerances so fit and sealing performance match what the stern drive was originally designed for, helping prevent oil loss and water intrusion that can damage internal drive components over time.

This seal cross-references directly to the OEM Volvo part number, making it a straightforward like-for-like replacement for boaters servicing their stern drive as part of routine maintenance or a leak repair. Its compact, lightweight design (0.01 pounds) reflects its role as a precision sealing component rather than a structural part, and it is intended to be installed exactly where the original OEM seal was located.
