14475Re: Prop Question: Will a couple of nicks cause the prop to slip?
- Mar 5, 2007Hi Max & Bryant
I checked the prop on the "Prop Torque Fixture" and found out that
the prop would not hold the 40 ft-lbs. When the torque was applied
the to the prop it slowly creeped around. I guess I need a new
prop. I found a new one online for less than $60. Thanks for all
your help and opinions.
