Lower Unit

Here is another lower unit question. Probably redundant. How can I tell what lower unit I have.

Two reasons for this question.

1) The lower unit was changed out under warranty in 2012
2) Shift shaft cover on mine is plastic and white. The Mercury Parts site identifies it as part number 858934 and this is cast metal and painted black. Mine is part number...8M0047129. This part number shows up in the Torquemaster II parts list here...

So I am confused and need help. Also what shaft length do I have on this motor. 20" or 25"? The motor is attached to a 2009 Champ 206CX

Thank you,

Tom
