Anyone out there know where to order an actual owner's manual for a 1975 Johnson 15hp? Not a repair manual but the book you get when you buy a brand new motor.
I bought a used boat and a 15hp Johnson motor, but the owner didn't know the age of the motor. The model# is 15R75C, Serial# is E4207544. I'm guessing it's a 1975. Am I right? Thanks in advance. :) :)
