Wow!!
Are these pictures before & after of the same motor?
Did you do the restoration?
You noted earlier that my A # 4215 does not have a cavitation plate.
Any idea when the cavitation plate was added?
Same motor. I cleaned it up. These old motors keep
me busy through the winter as well as using them in
the summer. This example had a broken
crankshaft. May be the reason it was mostly
complete, and in otherwise good condition. A
replacement crank, gas cap, and spark plug wires
were all that were necessary for this motor to be
running again.
As Stanly has noted there were many little changes,
like cavitation plate, through the years.
That’s not me, but a suspect Stanly can provide you
with those details to look for that would be correct
for your example.
Tubs.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
