1. 1960 and 1961 Elgin 60 HP (Very rare.  Came on Sear's toy boat).  These were made by K&O and sold by Sears as part of the "Weekend Skipper Set" which included a metal Rambler Station wagon, metal boat trailer and the Viking plastic boat. They were sold through the Sears catalog.  Elgin was a real outboard motor that was manufactured for Sears by the Scott-Atwater company.  Cheaply made but still a pretty neat motor to have because it's so rare.
The Weekend Skipper set first appeared in 1959 with a Sea Dart outboard.  Then, in 1960 and 1961, they used the Elgin 60 Hp.  Finally, in 1962 they used the K&O Johnson 40 Hp below.

2.  Johnson 1960 40 HP (very common).  Probably the easiest motor of all toy outboards to find.  They're everywhere!  They were sold individually in a small box and also as part of many toy plastic boat combinations.  They are cheaply made, and are often found not working and with decal problems.

3.  Johnson 1965 40 HP.
Another cheaply made plastic motor but a lot harder to find than the 1960 above.  Still, it's hardly a rare motor and no one is looking for it.

4.  Evinrude 1961 Lark 40 HP
This is the best looking of all the plastic toy outboards that K&O made.  This looks just like the metal version.  They really did a great job on this motor.  Even the wing on the side is well made.  A good motor to get if you can't afford the metal one.  Pretty hard to find.

5.  Evinrude Lark VII 1965.
This one has sentimental value to me because I had the real one of these on a 1952 Lyman 16 footer.  Well done by K&O but often has bad decals.  A little hard to find.  I would like to find a mint one of these for my collection.  They were sold in a colorful bubble wrap.

6.  Evinrude 40 HP Lark.
The same motor as above except in white.  I believe this is 1967.

7.  McCulloch 75 HP
This is a great plastic toy outboard.  It's probably the best plastic toy outboard ever made, even better than the 1961 Evinrude above.  It's got wonderful detail to it.  It was sold in a small cardboard box.  Not a K&O product.  I'd like to find a mint one of these.

8.  1965 Mercury Merc 500.  A very rare plastic motor that was seen in the 1965 Fleetline/Craft Master ads.  They were sold in bubble packs along with the Evinrude Lark VII and the Johnson 40.  This is not to be confused with the very common Mercury Merc 500 that you find from time to time.  This is a true K&O motor.  I only know of three  or four in collector's hands.  

9. Fleetline Johnson Meteor 1965.  This is one of the nicest plastic motors ever made by K&O Fleetline.  It's a replica of the Johnson Meteor, which was a great looking and very popular motor.  The motor on the right was professionally restored by Chip's outboards. The original motor was all yellow from age so chip sanded, primed and used original OMC paint to get it back to new then added clear coat to protect it.  Great job Chip!

10. 1960 Johnson 75 HP model kit.  A great plastic model kit.  I had this one as a kid and loved building it. I especially liked the handle on the back of the cowl just like the real motors.  These are becoming very rare, especially in unbuilt condition.  The same motor was offered already built by Fleetline in the standard box.

11.  Johnson 40 HP motor around 1968:  I don't think this motor was ever made.  I think this is a repainted motor but it looked great so I'm putting it on here.  Does anyone else have one?
