I've done it on mine. Don't touch the flange, it's the best part. Inside the flange hole there are two notches to help you hold it while unscrewing. Buy a cheap socket (for ratchets) of the same size of the inside hole. Then grind a slot to allow the socket to slide in and lock itself on the notches. You'll need to be two for this job to unscrew the thing. It will be fairly easy once it starts moving. You'll probably be surprised at how well and healthy the hull looks underneath, this was well done. Unless the flange turned rose (meaning the zinc inside is gone), keep it and replace everything else. Antoine (C&C 30 Cousin)
