They are, or were, bronze bolts.they hold the housing on place. The housing
is also threaded onto the stern tube. If you plan to remove it first the
bolts then carefully unscrew the housing from the tube. It is helpful to
have another person inside with a pipe wrench on the tube to prevent it
from turning and breaking the seal  between the boat hull and the tube. If
the tube is loose, remove all of the gray definite caulk and rebed it with
5200. This may require removing the shaft and tube.
