I have a 1956/57/58 (not sure which year exactly) Johnson 35 hp with a model number of 35531. It was built in Canada.
I just recently downloaded the Johnson “Red Book” and saw the chart for the 1958 Johnson 35 horse power with the following model #s: RD-19C, RDE-19C and RDS-20
Were there different model #s depending on which country the motor was built in?
The other issue I have is that this same motor is likely a mix of different parts. So the exterior plate states as above – Model # 35531 but on the interior part of the motor, the circular silver coin shaped plate shows a big M (from my research, it doesn’t appear to stand for Mercury) and the model number is 0385564.
any thoughts on identifying the year and make of the engine?
The squared M is OMC’s trademark. 385564 is the serial number. Probably a Canadian motor. Yes, Canadian and USA motors have different serial numbers.
35531 is an Evinrude 1962 40hp.
RD-19C is a rope start motor 1958
RDE-19C is an electric start motor 1958
RDS-20 is a 1958 Johnson Super Sea Horse (Super Quiet) 35hp
