It's a McCulloch. The Los Angeles based chain saw manufacturer took over
the Scott-A****er company from the namesakes in 1956, the name was soon
shortened to Scott, & by 1964 it was McCulloch. Same company, just a name
morph. Your 7.5 was based on the popular "Fishing Scott" rooted in the
late 50's into 60's production.

And didn't Scott start the low profile look to fishing motors? I remember
them making a big thing of the built in bailer back then. I also remember
the big Scott's as being rather noisy. A high school buddy of mine had a
Crestliner with a 35 hp Scott and it was much louder than the Evinrudes we
ran on our boats.
