    Close, but no cigar. I make it to be a pre-WWII Champion. Predecessor to Scott-Atwater

    I’m wondering about that serial number.

    482 falls between the 481 and 483 Scot Atwater models built in 1948 ? ? ?

    But that ain’t no 1948. That’s why the number looks suspicious to me. It has the 4-bolt head, last used in 1946. And it has the gearcase cap ahead of the prop, used in pre-war years.

    Where did you find that supposed serial number? Can you find the Tillotson number on the carburetor, or the numbers or picture of the magneto?

    That thing is bugging me. It has the 1946 S/A exhaust housing, but with water intake holes. The lower unit is pre-war style. I’m suspecting it is something S/A cobbled up right after the war ended, from parts in storage. There was a big rush to get outboard motors back into production. Anybody else know?

    My apologies , I’ve misread the serial number , it should begin 462 . I went over it with a wire brush and it became clear

    Aha!!! Now we’re getting somewhere. 462 is a 1946 Firestone 3.5hp, made by Scott-Atwater. I was a bit confused because my 1947 Firestone had the newer style lower unit. In fact the whole thing looks considerably different. Posting a picture of the 1947 Firestone 3.5.

    Don’t know. But probably not, considering it was sort of cobbled together in a hurry. And it has the push button choke which would not be compatible with lower cowlings.

    Sure wish I knew more because my dad bought a new Firestone back in the late 1940’s, when I was a pre-teen. It was a major influence in my life, and I can’t remember what it looked like. But that’s another story.

    I’ve spent alot of time on Google images and can only find one which has the same tank and it doesn’t have a lower cowling either . I don’t see any mountings for one . What would it’s original colours be ?

    The 1947 that I posted was original paint, Don’t quote me on 1946.
