This is a used engine component and shows normal signs of previous use, including carbon buildup, oil residue, discoloration, and cosmetic wear. Please carefully inspect all pictures for exact condition before purchasing.

Part is being sold exactly as pictured. We recommend that all used internal engine components be inspected and measured by a qualified marine technician before installation.

Please verify the OEM part number and compatibility with your exact engine model and serial number before purchasing.

For fitment, I would advertise it primarily for the 2005–2011 Yamaha F250/LF250 3.3L V6 generation, with exact fitment depending on model/serial revisions. The 2012 F250XA parts catalog already shows a different connecting-rod assembly, so I would stop the compatibility at 2011 rather than risk an incorrect sale.
