Got this mechanical marvel all back together,
but it will probably spend the rest of my life
as a “rack filler”.
The “red” prop that came with it was just stuck on the
end of the shaft, and the shaft threads didn’t even
protrude far enough to put a nut on.
I thought about machining it to fit, but
then I realized, it was a “right hand” prop, and
this unit needs a “left hand prop”.
I thought, perhaps I could just switch the battery leads,
but alas “no”, it still turned the same rotation.
I found a tiny little “left hand” prop on a junk trolling motor,
and threaded the bore to fit the drive shaft.
It doesn’t run real “true”, nor is it big enough from what
I can tell from advertisements.
Not sure what to think about the rheostat not “Rheostating”.
Only a tiny speed variation can be achieved throughout the
control stroke.
All that being said,
Q – What would prevent the rheostat from regulating the speed? Grounded?
Q. Does anyone know if the correct prop “screwed on” the driveshaft threads,
or was held on with a nut and cotter pin?
I can’t find any photos good enough to show that detail for the curved driveshaft models.
