the tag located at starboard rear of merc 190 give me a number A365225 and that does not compute on any search site. I want to know the year of my engine (not original to boat) to order correct parts. It has 4 bbl and 190 tag on valve cover, but numbers there are unreadable. thanks!

Looked up the number here
https://www.mercurymarine.com/en/us/parts-and-accessories/parts-catalog

Selected parts catalog and then entered the number, it comes up as a 1977-1993 TR/TRS Belgium transom assembly

What are the block casting numbers?
