PM T2, Thanks for all that data. Much appreciated.
Interesting, but I see no mention of the Standard Speedster.
I’m not sure what the "Evinrude-Elto model year guide"
is exactly, but is it floating around the internet?
Thanks
Update – just learned in "Old Outboard Book" that
the Service and Standard speedster are one in the same, and
In 1929 the Standard / Service Speedster was 7 hp. It was "upped" to 8 hp in 1931
Also, that the High-Speed Speedsters had aluminum pistons, Auxillary air intakes, etc.
