Re: Overpropped; What to do?
to repitch a prop the blades should be twisted when heated up. More of an angle or less of an angle. Then compare it to a jig of angles for that particular prop.
Suppose you have a 12X9 prop. The 12" diameter is measureable by you. The 9" means that in a tub of Jello, one rotation of the prop will advance it 9" in the Jello. Lessen the angle of the prop blade, and it only will go 7" for example.
The prop pitch can also be changed by cutting of equal amount of the blade, but that is a road far less travelled.
