Evinrude 90 - Want to find Model and Year

[BOAH]

I just purchased an old boat with an Evinrude 90. I've got so many questions, I don't know where to begin so I thought I would start with an owners manual. Well to get the right manual, I need to know what motor I have. The only numbers that I can find anywhere are ones that are stamped in various locations on the motor.

Including:

317851 - Side of cylinder head
317850 - Side of cylinder head
310532 - Side of cylinders
318140 - Intake
335390

Any help would be much appreciated! Then I'll start asking real questions!

Found a little more information. Looks like the number stamped on the freeze plug is 115393M and then a second set of numbers of 1000883. Doing a little more research says that the 115393M is a 1973 115. If that's right, any idea what the second set of numbers is for?

Thanks again for any help.

Maybe a coincidence , are you Triumphrick's friend with the mystery (90) 115, indeed it is a 73/74 according to the head stamp part number.

Second set of numbers should be the serial number of the motor
