Notable Part numbers

From a AQ125A 4-Cylinder Sterndrive SN 76 79009187 (B21 Block) Also found on AQ120B AQ125B AQ140A BB140A & AQ131

From my research it seems that this might be compatible with other Yamaha 4hp 4-stroke outboards 2000-2006 & newer

Should be everything you need for a basic rebuild
