I have the mechanic coming over who did the rebuild. On the phone he
told me that if the boat had not been run for six months (since the
rebuild was completed), that rust may have built up in the cylinders,
or on the valves, and that this might account for the oil pressure
problem. Does this sound reasonable?

No, not to me.
