go get one of those plastic prop wrenches. they have a small spike on them that fits in those little holes on the star washer to bend them out. bend them all out so there not recesed into the funny looking washer, and give it a good jerk on the nut..
the springy part{with the tabs on it} comes off with the nut. the funny looking washer {the tabs fit into} stays on the shaft.
dont lose the spacer behind the prop..
That funny looking star washer locks the nut to the shaft. You need to make sure all the tabs are bent up out of the slots in the nut. After you ge tthe nut off you should find the star washer is keyed to the shaft somehow...
