45 hp Chrysler #455HH-4306- Can't find this engine on most part sites

Hello,
I have the engine above but can't find the # on most part sites. Can someone help me figure out the exact year? All along I am thinking it is a 1972.

1975. Mercury stills sells parts for this along with Doug Russell

It appears to be a 1975 model according to the serial number on the DougRussell.com site. I found the water pump impeller part number to be: F433065

You can look on this diagram and part list if you need to replace the body of the water pump and the back plate. Chances are that you can just clean them up though.

Here's the thread on changing the impeller, different motor, but it will give you an idea.
