Motor ID

[Carlasdaddy]

I was given this older Johnson outboard today. There is no model identification anywhere on the outside of the motor. I have attached photos of it. Does anybody have an idea of what year and model it might be? I’m guessing it’s a 1955 JW-11 3hp. Anybody know where I can get a parts list for it?

Thank you for any help you may have.

I’d say it’s a 1960 some thing model.

I’m pretty sure going on the single clamp screw and the thicker trunk under the power head,it will be 1964 to 1966.

Yeah, I’m thinking 65-66 right angle drive model….

1964 = JH-19
1965 = JH-20
1966 = JH-21

Here is parts list for JH-20

Carlasdaddy: Back in 1955 the Johnsons were green.

I believe yours is indeed a 1966 JW-21. When you remove the cowling and look over the powerhead you should find an ID on what looks like a freeze-plug.

It is actually a JH-21E, which is a 1966 3hp extended shaft motor. When viewing the carburetor parts listing on marine.com, the parts list did not go with the diagram. I checked the diagram for a JH-20 carb and it looks identical to the JH-21 diagram, so I assume the parts list is the same. Am I correct?

Motor in the picture is not an extended shaft. It is a short shaft. If you think it is a 1966, the model would be JH-21. The trailing “E” only denotes a mid-year change IF there was a change. Otherwise, it means nothing. I don’t know of any significant changes in the carburetor, assuming yours has a fixed high speed jet, as a -21 should have

If it’s any help to you Carlasdaddy, there should be an I D plate showing model and serial numbers just above the thumb screw, in a recess on the mounting bracket (which clamps the motor to the boat)

If you look at the middle picture that you posted, I think you will find it……. it’s hidden behind the carrying bracket thats across the front of the motor.

To frankr: If you look on marineengine.com for a Johnson JH-21 and look at the lower gearcase group for a standard drive, item #38 (part#0310355) is a 5″ gearcase extension.
