A buddy just returned from an auction today with a boat, motor, and trailer in tow. As it turns out, the Johnson motor is missing the model/serial plate. Is there any way to identify the motor with just the serial. The serial from the freeze plug is E3435191. Just guessing, I'd say it looks to be a 20-25hp motor from the late 70's to early 80's but that's just guessing on my part. Can anyone help identify this motor. Thanks.
