Mint condition Evinrude Sportsman SN 4416-20249.how old is it and what is it worth?

The motor is a 1947. If it is in mint condition and runs good then I would say a low price would be about $130.00 to as much as $250.00. It all depends on the condition. Ebay tends to drive the price up. I have also seen what I thought was a sought after motor go for far less on ebay. If you get the right person it could go higher. I have a good running one I bought off a guy $26.00. A few parts later and I would value it at around $130.00 Hope this helps. Tom
