Serial Number Mount N Blade I Am Trying To Find The Serial Number On A 2hp Mercury Outboard Motor.?

I am trying to find the serial number on a 2hp Mercury outboard motor.? - serial number mount n blade

The engine cover is made of plastic, dark gray and "Mercury Marine Turbine" in white letters on it.
I searched everywhere and say no numbers or marks of components across made.Usually, where serial numbers are printed on the mount, but in this case.
Who knows what year model of my application? I have a picture of her, if I can somehow.
I need a fuel that a valve has failed and my Mercury dealer said that the role is no longer available and do not know to replace the age of the machine.
Thank you.
