Thank you for your reply. The tag on the trans. bracket has been removed.The ser.# I included is from the welch plug.The closest I have come ,looking at pictures, is a 1959 but it had a single fuel line from the gas tank. Mine has 2 lines,1 fuel and 1pressure line.Please helpIt's a 1959. That was the last year for dual line systems on OMCs. Plus, it was the only year they had the round appliqu? on the top of the cowling. 1960s had an arrow appliqu?.
Nice motors. I have three 10s to go through this winter - a 1955 Johnson, 1958 Evinrude and 1960 Evinrude.
1959 serial numbers were 1,743,081--1,995,465. So, anybody that said 1959 is the winner. Model number would be CD-16.
cd-16 is a 5.5
