Need help identifying my motor year

I’m trying to figure out what year and possible make my motor is so I know what spare parts to buy.
The motor is a Mariner 40 but has a Yamaha serial plate.
The plate is as follows:
Yamaha 40EL
6E9 L 415125

Any help identifying this motor would be greatly appreciated!
 
The early SMALLER Mariner motors were indeed built by Yamaha.-----That was in the mid 1980's----Top of this page is a box for----" engine diagrams "----Click on Mariner.

Thank you for the reply. I was aware that these Mariner motors were built by Yahaha. I have looked up my serial number using both mercury/Mariner and Yamaha serial look ups but have failed to locate a motor that matches the 415125 serial number.

Your serial number shows the engine coming up to be a 1985 40-H.P (EL) L= Long Shaft (20"), E = ELECTRIC START Model Number 7040525 http://www.marineengine.com/parts/mariner-outboard-parts/40c-twin-carb/6e9400231-thru-6e9423162---el

Have just purchased a mako 20, 1980. Has a mercury 200 black max v200. Cannot find any serial /model numbers where they are supposed to be. Found this on a core plug B250678.
Any help would be appreciated as need to order impeller kit.
