Subject: Re: scooter blades
The eye in the plastic wears sometimes and allows them to wobble -
change them out. Also, the yoke with the fingers will allow the blades
to pitch flater frio any given setting as well. The flex of the blades
actually works in your favor in many situations, as it pulls the tips
away from the shroud's narrowest pooint. Water will not compress, and
items passing through the blades and shroud are best not trapped between
the two, or then the shear pin is risked as mentioned in the other post.
