www.acmeoutboards.com has a service manual for the old Scott-Atwater motors.

where do you guys get all this info? this little motor runs good, the guy I bought it from said it hasn"t been run for yrs. pumps all kind of water, where would I find an impeller for it?

Well, in my case it just comes to me in my sleep...but seriously, it's part of being an old iron head. You accumulate it and then pass it along when needed. Check classifieds at www.aomci.org for an impeller source...there's also a guy on the Web named Brian Wilcox (Google the name) who makes impellers for older motors.
