I performed Google searches with:
3619 wizard outboard
3619 Scott outboard
3619 McCulloch outboard
Nothing came up, so I am assuming 3619 is probably part of a serial number or that there is probably not much information on the web. With these types of motors, knowing the make and horsepower is probably more important anyway. If I recall correctly, the Eska branded great grand children of the Scott motors, had serial numbers on metal tabs attached to a bolt on the power head.
The wooden stand sounds interesting. Perhaps could you upload some pictures?
