CARMOCAR Marine Fuel Water Separator S3213 — 10µm Spin‑On Filter with Clear Nylon Bowl

The CARMOCAR S3213 marine fuel water separator assembly is a complete spin‑on filter kit with a clear nylon collection bowl and 10‑micron element designed to trap water and contaminants from outboard fuel systems.

Keep your boat's fuel system cleaner and more reliable with a direct‑fit replacement that matches popular OEM part numbers from Mercury, Racor and Yamaha. This kit combines a reusable clear nylon bowl with a high‑efficiency 10 µm filter element, two spare O‑rings and a user‑friendly spin‑on design so you can inspect, drain and replace the filter quickly before a cruise or during routine maintenance.

How does the S3213 separator protect my outboard motor?

The S3213 removes suspended particles and separated water before fuel reaches the pump and injectors, reducing wear and performance problems. Its multi‑layer synthetic media captures fine contaminants while the clear bowl shows collected water for visual inspection.

• 10‑micron filtration captures small particles; >92% efficiency
• Clear nylon bowl reveals water/muck levels at a glance
• Self‑venting drain screw allows quick removal of separated water
• Spin‑on element reduces installation time and leak points

Which engines and OEM numbers does this kit replace?

This assembly is built to match form and function for many common outboard replacements, so it fits a range of Mercury, Racor and Yamaha applications. Confirm compatibility by comparing local OEM numbers and the included hardware to your existing assembly.

• Direct replacements: Mercury 35‑60494‑1, 35‑809097
• Racor equivalents: S3213, B32013
• Other cross‑references: 18‑7932‑1, 18‑7928‑1, MAR‑24563‑03‑00 and similar
• Includes bowl, filter element and two O‑rings for retrofit and maintenance

How simple is installation and routine maintenance?

Installation is straightforward: the spin‑on filter threads into the mounting bracket and the bowl drains with a thumb screw. Regular checks and periodic element replacement keep the system functioning without complex tools.

• Plug‑and‑play spin‑on design for fast swaps
• Loosen drain screw to remove water, then re‑tighten
• Run engine and inspect for leaks after replacement
• Replace element on schedule or when debris/water appears

What performance benefits can I expect after installing this kit?

By reducing water and particle contamination, the S3213 helps maintain fuel‑system tolerance and component life without promising specific outcomes. Cleaner fuel can support more consistent engine operation and reduce the risk of clogged nozzles and premature wear.

• Helps protect fuel pumps, injectors and cylinder components
• May reduce maintenance needs tied to contaminated fuel
• Clear bowl helps schedule timely servicing to avoid downtime
• Reusable bowl reduces replacement cost for future servicing

Who is this for: The CARMOCAR S3213 assembly is intended for boat owners, marina technicians and marine mechanics who need a reliable, OEM‑equivalent fuel/water separator for outboard engines. It suits anyone replacing worn or damaged separators on Mercury, Racor or compatible engines, and those who want an easy‑to‑inspect bowl plus a high‑efficiency 10 µm filter element for routine marine fuel maintenance.
