that is freeze damage to the manifold, those are inside wall pieces from your manifold. I would do a compression test on the motor and a cooling jacket pressure test as well.
get a new set of manifolds and elbows on order. only buy mercruiser or Barr. dont buy GLM or Sierra

It would help if we knew what vintage drive you are talking about. the old stringer drive and electric shift drives can grenade a section and not take out the other section. however the newer drives will share debris
I would suggest looking in the yellow pages for OMC service...
no, 1995 should be the AQ series, most likey an DP-C (290DP derivative)
the SM is a different animal, however the lower is similar in both design and shape, but NOT interchangeable.
if your thermostat is stuck open, the motor will never get to operating temperature to burn of condensation.
change the oil a few times, fix the thermostat issue and then take the boat for a good run at temperature.
