Looks like an Owen Dyneto motor, sold by Evinrude,
Early 1930’s I’m guessing.
Owen also supply those motors to Evinrude / OMC
to use as starter / generators on some bigger motors.
I looked up the model number (4029) and all is says it 1934-36 All Electric. 0006 means it was the 6th motor produced. I suspect there weren’t a lot of them manufactured. I think you will have a lot of interest in that motor. Be careful with what remains of the decal.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
