Welcome aboard
unlike cars where there is both an operators manual and a service manual, boats dont get anything like that
the original boat "manual" is a safety brochure showing that the pointy end is the bow and the flat end with the propeller is the stern, where the steering wheel is, and a list of dealers. pretty much it. usually printed on a single 8.5 x 11" piece of paper with a few folds in it.
in addition to that, the driveline (Mercruiser, Volvo, OMC, etc) manuals, the radio manuals etc are provided.
for the motor/drive manuals and brochures, you can go here:

what specific information are you looking for?
Also, since 1992, Chris Craft went thru a few owners and moves. doubt very much that they would have anything that old.
