While taking off the gear housing on my 2005 Alpha 1 Generation II to install new impeller this piece came out. Can't find where it goes, what it is, or even a pic of it in the manual. Can anyone identify what it is and where it goes? Thanks much!

Not sure what it is on your engine, but I have such a part on my OB. It is listed as an exhaust port baffle. Mine goes in the lower mid section exhaust outlet with three bolts...

There are some differencies depending on installation so you will need to verify that this is the correct one. They usually falls down when the engines overheats or they get (very) old.

Does anyone know which manual covers the parts and/or removal/installation of the these shutters and the Y pipe? I can't seem to find it in the three manuals I have which are #25...#14...and #37. I have a 2005 Mercruiser 4.3L TKS...thanks.
