Captain 'Bozo' had dinged the props on a 120' footer right after taking delivery; got the call to remove the damaged props, have them re-done, and reinstall them. Took two 350lb lift bags as the first set up of 1 350lb and 1 200lb lift bag ended up with the 200lb bag blowing up in my face and prop sailing to the bottom... FAST! Got both props removed and reinstalled. Final weight for props was 710 pounds each.... Prop nuts were 80 pounds a piece...
