Hello All,I finally got my new prop. So I am anxious to install the new shaft and prop. My question relates to the nut that holds the prop on the shaft. On the old setup there were several holes drilled in the nut so a pin could be run through the nut and shaft. The new nut has no holes. Am I suppose to drill a hole when everything is tightened down? Do I not need a pin to keep the prop nut from coming loose?Thanks,Tim Pinkham~La Juin~
