Where Is This Filter Fitted?
The filter is fitted inline in the petrol supply hose, normally underneath the outboard cowling.
On these carburettor-fed two-stroke engines, it helps trap dirt and contaminants before fuel enters the carburettor.

Important – 60 mm Versus 45 mm Filter
THIS LISTING IS FOR THE 60 MM LONG FILTER FOR 6 MM FUEL HOSES.
Do not confuse it with the smaller 45 mm filter for 5 mm fuel hoses, sometimes cross-referenced with Yamaha 646-24251-02 and Mercury 35-80365M.
Some aftermarket catalogues combine these references, but the filter dimensions and hose connections must be checked.
Please confirm the original filter, hose diameter, engine model and serial number before purchasing.
If the part looks the same as yours, it is not always the correct one for your outboard.
