10-Micron Replacement Fuel/Water Separating Filter Element for Outboard Engines
This Seachoice 10-micron fuel/water separating filter element removes water contamination and fine particulates from the fuel supply before they reach the engine — protecting carburetors, injectors, and fuel pumps on both 2-stroke and 4-stroke outboard engines. The water-shedding cellulose element captures contaminants at 10 microns, and the coated steel canister resists corrosion for long service life.
Produced in an ISO-certified facility to meet or exceed OEM standards. Direct replacement for Yamaha, Mercury Marine, and Sierra filter applications — see the compatibility list below.

Best Use Case
This filter element is the right choice for routine maintenance on outboard-powered vessels where water contamination in the fuel supply is a concern — particularly in humid climates, boats with older or vented fuel tanks, or vessels that sit between uses. The 10-micron rating provides fine filtration suitable for both carbureted and fuel-injected outboard engines. Replace on a regular maintenance schedule or whenever the filter shows signs of water accumulation or restricted flow. If you need a complete assembly including canister and bracket, see the Clearchoice kit below.

Parts Desk Insights
SKU 50-20933 is a replacement filter element — not a complete kit. Customers who need the full assembly (canister + bracket + element) should be directed to the Clearchoice kit (SKU 50-22403). The OEM cross-references are the primary search driver for this product: Yamaha MAR-10MEL-00-00 and MAR-FUELF-IL-TR, Mercury Marine 35-8M0154754, and Sierra 18-7866 are all direct replacements. The ISO certification note ("TS1649" in the original data appears to be a truncation of ISO/TS 16949) means this is manufactured to automotive-grade quality standards — a meaningful credibility point vs. generic aftermarket filters. The 10-micron cellulose element is suitable for gasoline outboards; diesel applications may require a different element specification.
