Mercury ser # help & power trim

[oriolesxx]

My Mercury 50 hp has a ser# clearly stamped 6420009 but the websites I enter it on says it doesn't exist. What is the year of the motor?
Also, what power trim will fit this motor? It doesn't currently have one.

Inside the parts diagrams above, there are two sections that cover the POWER TRIM COMPONENTS (WITH) (or Without) CIRCUIT BREAKER AND FUSE)
