Re: Koban inboard motor

.
there is probably not much, I guess
found one picture of an inboard in Arlan Carter’s "the American Rowboat Motor" book.
3 hp made from 1916 – early 1920 ‘s
if the serial nr. is also on the circular plate at the top of the crankcase, you can figure out
from what year your motor is.
