thanks guys yes it was very fun when I was a young teenager to build that rig.

I seem to recall the propeller was bigger than the eight or 9 inches that would appear to go onto the lower unit I just purchased on eBay

I’m gonna have to find a resource to the propeller sizes of the various outboards in 1928 from Johnson. I pretty much remember that it was a two cylinder outboard.

and if I go with this lower unit that I just obtained, it will need a propeller anyway

as I recall, I didn’t have the pulley ratio was quite right and the engine was pretty much lugging which made it sound like a one lunger.  but that actually seemed more like a feature rather than a bug!

also I rigged up the speedometer from my Schwinn bicycle to one of the shafts so I had like a little tachometer on it lol

it’s too bad my parents couldn’t give a shit enough about what I was doing to take a couple of pictures. But on the other hand since I was left alone I could go anywhere I wanted in the contraption!
