quote SquierKA39:
The impeller is more of a squishing than a scooping. Look at how the newer OMC rubber ones work. When in place they are also flexing back, not scooping.
I would imagine someone found many moons ago,that the rubber impeller with contact on
all sides was more efficient than a steel impeller, with much less contact .
I don’t remember learning this fact, but what brand came out with the
rubber impeller first?
