The Seachoice 50-21016 is a 20-micron full-flow oil filter element designed as a replacement for canister-style marine oil filter housings. Unlike spin-on filters, this is a serviceable filter element that fits inside a reusable filter housing — built to meet or exceed OEM specifications for marine engine applications.
Key Features
- 20-Micron filtration — captures large contamination particles before they reach lubricated engine components
- High-efficiency cellulose filter element — extends service intervals and reduces flow restriction
- Engineered for the marine environment — designed to withstand the demands of on-water operation
- Manufactured in an ISO/TS 16949 certified facility — meets or exceeds industry quality standards
Parts Desk Insights
Best suited for engines equipped with a canister-style (bowl-type) oil filter housing that accepts a replaceable element rather than a spin-on filter. This style of filter is less common on modern outboards but is found on certain inboard and diesel auxiliary engines. Confirm your engine uses a canister housing before ordering — if your engine uses a spin-on filter, see the other Seachoice Full-Flow Oil Filters in this series. Cross-reference: Sierra 18-8880.
