Your motor is pretty common but there is a demand
for them. Condition affects value. The picture you
have provided gives little to speculate on condition
other than its not pristine. If I was to attend your
sale and find your motor has no broken parts, normal
compression, gas tank is not dented, sound inside, with
just surface rust on the outside, I would be interested
in it up $125.00. That’s is what it would be worth to me.
To someone else it may be worth several times that
or no more than $25.00. How many antique outboard
motor collectors do you expect to attend your sale?
There is no way to know what the value will be to those
who attend your sale other than they will be different.
You could put $50.00 on it and still have it at the end of
the day.
