Re: 1927 Johnson Outboard
If the first part of the serial number on the rope plate is an A, then it is an A-XX, not a J-25. The A-series were the twin cylinder, opposed motors. The J-25s were single cylinders. A-25s were 1925 & 1926 model years. A-35s were 1927 & 1928 model years. What does the parts and service manual you have say on it? I'd need to find my serial number list to nail it down for you...
