The changes over the years were, carb and cylinder mainly. The displacement never changed. Some internal changes, rods went from bronze to aluminum. Too many things to lot here. The later ones, from KA39 and up were really the same internally. The KS has rope start, KD was deluxe and had recoil. Yes, they all use the prop was for cooling. The A, KA, was added when they changed the lower unit. Props are opposite turning on A and non a older versions.
See the photos page for a picture of my 1930 K-50 pushing my Thomson 16’ boat, also a 1930. Hope this helps.
quote 10717:
I am looking for a K and trying to figure out the changes over the years. The carb seems to have changed in 1
935 (improved linkage between the carb and mag?) and the displacement seems to have increased in 1939. The designation went from “K” to “KA” to “KS” and “KD”. I think “S” was standard and “D” was deluxe (with a recoil starter), but what does “A” mean? Did they all use prop wash for cooling? Goal is to use the engine on my great uncle’s 16′ Thompson cedar strip. I would appreciate the pros and cons of the variations. Thanks.
