Serial number info

[sitchy27]

Hi everyone, new here. Just bought 25 hp but its missing the tag off the transom bracket and wanted to know if there are any other places to find a stamp on these motors, I was told its from mid to late 80's. I found a stamped number on the block when i removed the coils but it didn't match any of the numbers i found on browns point. The stamp reads 36607-223458. Any tips or ideas are helpful as i need to get parts ordered. Thanks.
