What's the diff between OS 32F and 32SX?
OS doesn't publish a manual or exploded view of the 32F. I have one that needs bearings, and it appears the 32F and 32SX are different (as far as bearing part numbers go).
So what's the real difference?

Keefer,
Both engines use the same rear bearing; a 6901 12x24x6 mm open bearing.
They also both have the same O/d front crankshaft (9 mm).
But the F engine uses a lower load 689Z 9x17x5 mm bearing, to the SX's 699Z 9x20x6 mm bearing.
This is probably to counter the tendency of some modelers to use badly unbalanced props and/or to 'perform' frequent prop-strikes, that abbreviate front bearing life...
