624-24521-01 – Cap Filter – Yamaha

The 624-24521-01 Yamaha filter is a genuine OEM cup filter cap for small Yamaha outboard engines. This filter cap holds the internal element that traps water and debris. Also, it protects pumps and lines from contaminants that can damage fuel or fluid systems. Because this cup fits Yamaha’s exact specs, it screws on easily and seals cleanly.

This Yamaha filter cap installs on small outboards such as 4 HP and 5 HP models. First, remove the old filter cap and element. Then clean the housing and check for debris. Finally, thread on the 624-24521-01 Yamaha filter securely. Do not overtighten. The cap threads and housing fit together without forcing. This cap helps keep fluid clean and helps the internal filter work correctly.

In marine engines, dirt and grit can damage pumps and injectors. Also, water contamination leads to corrosion and reduced performance. By keeping the filter cup in good condition, you help your engine stay reliable. Also, using genuine Yamaha parts helps maintain correct fitment. After long use or storage, parts like this filter cap often need replacement. Installing a new cap during service prevents fluid bypass and keeps your system clean.
