Seachoice — 10-Micron Fuel and Water Separating Filter Element — 50-20933

Seachoice 10-Micron Fuel and Water Separating Filter Element — 50-20933

Keep an outboard fuel system protected with this Seachoice replacement filter element. Its 10-micron filtration is designed to separate water and capture fine particles before contaminated fuel reaches sensitive fuel-system components. This listing is for the replacement element, not a complete filter assembly.

Compatible Applications

• 2-stroke outboard fuel systems
• 4-stroke outboard fuel systems
• Applications using a compatible fuel and water separating filter assembly

Fitment varies by engine, filter assembly, and connection details. Confirm the exact application and replacement number for your outboard before ordering.

OEM Cross-Reference Notes

The product record lists the following cross-reference numbers: Yamaha MAR-10MEL-00-00 and MAR-FUELF-IL-TR, Mercury Marine 35-8M0154754, and Sierra 18-7866. Cross-reference numbers do not replace an exact fitment check, so match the filter assembly and engine application before ordering.

Technical FAQ

• Is this a complete fuel filter kit?
  No. This listing is for the replacement filter element. A complete assembly may include a canister, bracket, or other parts.
• What does 10 micron mean?
  It identifies the filter's stated filtration rating. Use the rating specified for your engine and filter assembly.
• Can I use it on any outboard?
  No. Confirm the engine application, filter assembly, and replacement number before ordering. The product record identifies 2-stroke and 4-stroke outboard use, but does not establish universal fitment.
• Is it suitable for diesel systems?
  Do not assume so. This listing identifies gasoline outboard applications; verify the required element specification with the engine or filter manufacturer.
• What should I replace if I need the full assembly?
  Look for a compatible fuel and water separator kit that includes the canister and bracket, rather than ordering this element alone.

Parts Desk Insights

Best use case: Choose this element when servicing a compatible fuel and water separating assembly on a gasoline outboard and the element itself needs replacement.

Common mistake: Ordering this replacement element when a complete canister-and-bracket kit is needed. Check what parts are already installed before ordering.

Sizing and fitment guidance: Match the 10-micron rating, assembly, connection details, engine application, and cross-reference number. Similar-looking elements are not automatically interchangeable.
