Has any body tried to replace the thru hug exh prop. I can get the nut off with an impac but can not remove. Went to the dealer and was told that this model needs to be burnt off because of the rubber shock hub. I guess that I can thank the heavens that all I wanted to do was put a new prop on and use the old as a spare.. What the hell would you do out in the shallows at low tide and you bang up a prop. Any help in this crazy problem will surelly be appreciated. I've included a picture of the prop. This is on a 2002 Merc, 25hp EL long shaft. I have never heard of a prop that had to be burnt off, dammit it really pisses me off to think that if I don't have the ability or whatever to build a better system than this, I'll be dammed. .
