I am definitely confused. I have found the "shelf" on the block where the number should be stamped. Yet, the only thing stamped there is an "s". There is the number 33020 stamped on the id plate on the rear mount starboard side. Could it be that the Crown Special was manufactured past this series?:

Starting serial number M47S-20001
Ending serial number M47S-24400
from 4/20/55 to 2/27/57
135HP @ 3600
265 CID

also I have seen a classified ad with this number: M47S-3 R 30859S. This person claims this is out of a 1957 boat.

Is it possible that there were more crown specials made after 2/1957? and that mine and the one above may be from a later production run? 33020 may be a later date than the above referenced classified engine? I do find a casting on the gear that looks like a date of 11/2/1957.

Any ideas would be appreciated.
