I?m not sure I?m doing this right. I removed the 15mm nut then there is a 21mm plastic nut/spacer. Does the 21mm nut unscrew or does it just slip off. The parts breakdown and service manual are not really helpful. To complicate things the prop may be stuck so it is not simply coming off. I tried to unscrew the 21mm nut but it only moves back and forth 1/16? which makes me think it is not supposed to unscrew.
