Thank you for this information !
I’m now thinking the 2nd motor is probably a KB-1A – On this right side view, it looks like there’s a carburetor bowl, so then it’s the later model with the Tillotson.
But I’m also thinking that there were some parts swapped – The carb knobs look like those on a KB-3, and the transom clamp is the heavier duty double screw type from the later motor – So, it will be interesting to look at that serial number tag .
