The motor with the black decal is #19, and would be a 1931 motor, it has the four-hole flywheel and no toggle switch, and uses the older style timer.
The one with the toggle switch is in the 800's, it might be a 1932 model. It has a three-hole flywheel and the later style timer. It also has the primer button on the bottom of the carb (bottom RH side if you're standing in front of it), which the earlier one does not.
Hope this helps.
Thanks, I'll add the info about the switch to my notes.
From what I read, it sounds like that during the depression, they may
have used parts from multiple years to get another outboard out the door!
My carb has a spring load button on the bottom of the carb,
but appears to be missing a knob on the top.
Is my 1930 Speedster suppose to have a three hole flywheel?
