I have a 1976 21 foot formula thunderbird with a 302 and a mercruiser 370 stern drive. It sat for several years and now will not turn over. Engeine turns about 5-10 degrees when ignition turn, but will go no further. Prop also turns small amount when engine turned, even in neutral. In neatral prop will not free spin. Drive train seems to be locked together and jammed. How do I trouble shoot to track down area to focus on.
