Yamaha Air Cleaner Element – SKU 6S5‑E4451‑01‑00
Supercedes 6S5‑E4451‑00‑00

Fresh air in, salt and dust out. This updated filter slides into the V‑6 airbox on F225, F250, and F300 outboards, delivering cleaner intake flow than the previous version it replaces. Yamaha reshaped the pleats and switched to a tighter‑weave cellulose media, so every piston gulp gets plenty of oxygen without the grit that scores cylinders.

• High‑capacity pleated core packs 20 percent more surface area than the earlier 00‑00 model
• Moisture‑resistant treatment lets the element dry quickly after foggy runs or heavy spray
• Molded nitrile rubber gasket seals tight against the airbox lip, preventing bypass leaks
• Color‑coded end cap makes it easy to spot when you’re sorting spare parts in the hatch
• Direct fit for all 6S5‑series V‑6 four‑strokes—drop it in at the 100‑hour service and go

Replacing a clogged or aging element restores crisp throttle response, steadier idle, and a touch of fuel savings on long cruises. It’s a five‑minute job that keeps corrosive salt crystals and airborne debris where they belong: outside your engine. Swap the filter, close the cowl, and breathe easy on your next run offshore.
