Description
Overview
The iFJF S3213 Replacement Filter Cartridge 3-Pack delivers 10-micron precision filtration for your marine fuel water separator housing — protecting your outboard motor's fuel system from damaging water, rust, and fine particle contamination. Designed as a direct drop-in replacement for the S3213 housing, these elements separate water from fuel before it reaches your injectors, preventing corrosion and power loss on the water.
At $6.33 per cartridge (vs. $10+ for single replacements), this 3-pack gives you the best cost-per-service in marine filtration. Whether you're running Yamaha, Mercury, or Volvo Penta outboards, the S3213 element fits standard S3213 housings and keeps your engine running clean and dry. Engineered for saltwater environments and ethanol-blended fuels.
Key Features
-
10-Micron High-Efficiency Filtration — Captures fine particles, rust, and emulsified water before they reach fuel system components.
-
Water-Separating Media — Specialized coalescing media separates free and emulsified water from fuel. Water in fuel causes injector corrosion and power loss.
-
Marine-Grade Construction — Built to withstand the harsh marine environment: saltwater exposure, fuel alcohol content (up to 10% ethanol), and vibration from outboard operation.
-
3-Pack Value Pricing — $19 for three cartridges ($6.33 each) vs. $30+ for three singles. Stock up for the full season.
-
Direct Drop-In Replacement — Fits S3213 fuel water separator housings. OEM cross-references: 35-60494-1 (Mercury), 802893Q01 (Yamaha), 18-7932-1 (Volvo Penta), S3213, S3214, B32013.

Why Choose iFJF
Water in your fuel is the #1 cause of outboard fuel system failures — corroded injectors, failed fuel pumps, and varnish buildup add up to hundreds or thousands in repair bills. The S3213 water-separating element prevents all of that for a few dollars per season. Unlike generic filters, iFJF cartridges are manufactured to tight tolerances for a secure seal in the S3213 housing.
Frequently Asked Questions
Q: How do I know when to replace the S3213 filter cartridge?
A: Replace when you notice engine performance issues (hard starting, rough idle, power loss) or when the water separator bowl shows visible water accumulation. Replace annually before spring launch or every 100 hours of operation, whichever comes first.
Q: Will this fit my Mercury 35-60494-1 housing?
A: Yes. The iFJF S3213 cartridge is a direct replacement for Mercury part 35-60494-1 and all equivalent S3213 housings from Yamaha and Volvo Penta.
Q: Can I use this filter with ethanol-blended fuel?
A: Yes. The filter media is compatible with ethanol-blended gasoline up to E10. Ethanol absorbs water from the atmosphere, making water separation even more critical.
Q: Is this the same as the Sierra 18-7932-1 filter?
A: Yes. The Sierra 18-7932-1, Mercury 35-60494-1, and Yamaha 802893Q01 are all equivalent S3213-type filter cartridges.
Q: Do I need any special tools to install this?
A: No tools required for the cartridge replacement itself. Simply unscrew the housing bowl, remove the old element, insert the new one, and hand-tighten the bowl back on.
