❓ FAQ
Is this the complete filter assembly?
No — this is the replacement filter element (cartridge only). You need the S3213 housing (sold separately) to use these cartridges. Get the complete housing here →
How long will 3 cartridges last me?
At the recommended 100-hour / once-per-season replacement interval, this 3-pack covers three full seasons or up to 300 hours of engine operation.
Will these fit my original OEM housing?
These cartridges are designed for the upgraded S3213 housing with the spin-on bowl design. They cross-reference with Mercury 35-60494-1, Yamaha 802893Q01, and Volvo Penta 18-7932-1 elements — but always verify your housing style before ordering.
Do they work with diesel fuel?
Yes — the 10-micron media is rated for both gasoline and diesel marine applications.
What's the difference between this and a spin-on filter?
This is a cartridge-style replacement element. It drops into a reusable housing instead of spinning onto a threaded mount. The advantage: you only replace the filter media, not the entire canister — saving money and reducing waste.
