    I recently purchased a Johnson CD-15 along with a pressure tank. The tank is unlike any I have seen in the last 25 years. It appears slightly larger than a 6 gallon tank. The “mechanics” look very similar to the OMC. The primer button is aluminum. The twin line wrapping holders appear to be stamped steel. On each end of the tank near the top are two stamped indentations.
    I saw a post that indicated this is a “type 3” tank.
    What is the approximate dates of manufacture and by whom?
    Thanks

    Sounds like a 1954 Johnson tank. NOTE;, this is parts list for a 4 gallon (CD) tank. 6 gallon is similar except for bigger.

    drifter, How about some pictures. 49/50 tanks are called tall boys. Does the fuel hose wind inside the top of the tank? The early 25hp tanks were similar to the tall boys but without the steel top where the hose was stored. Pictures are worth a thousand words!

    A three piece OMC “flat top” tank comes to mind. This picture shows the “two stamped indentations” at each end of the tank as described. My best guess on manufacture date is 1951-1952.

    Drifter, mine are a little different. No chain under the fill cap, and the decal is different. One came with a 1951 25hp Evinrude the other came with a 1952 14hp Evinrude. Probably some more Johnson engineering. Johnson improved outboards immensely during the early fifty’s. IMHO!

    Those are exactly like mine. Just the words “Gasoline” with no Johnson wording. Also, the tank has an internal baffle.
