Prop off, Prop on!

Shawn,
You should be able to use a drift ( normally a 1/8" will do) to drive out the broken pieces of key. It would probably be a good idea to have a second set of hands hold a buck (weight) on the opposite side to keep from banging the prop shaft sideways any more than necessary. Soaking the nut area with your favorite spray oil is always a good idea in areas like this. Next back the nut off a few threads but not all the way off. Leaving the nut loosley on the shaft will keep the prop from falling on the ground once the prop puller has done it's job. If the nut doesn't want to move then a nut splitter would be a better choice than damaging the shaft with excessive force. The most important part of the removal process is in finding someone with a good prop puller and the knowledge of how to use it correctly. Once you have successfully removed the old prop and cleaned the area use lapping compound to insure that the new prop seats comfortably on the shaft. The prop key should also be checked for clearance so that it does not keep the prop from mating to the shaft correctly.
Whew! Tom
