Got the coupling off. Had to break out the 3" angle grinder and metal cutoff wheel to cut the coupler off. No way that coupling was coming off with just a puller. Previous owner must've hit something, which explains the almost new prop. Lucky for him someone (factory maybe) installed a brass key on the coupling end. I have new brass keys for both ends now. Dealer told me I had to get a new shaft along with the new coupling. $340 for both, so I went ahead and ordered them. I hope they come in by this Friday so i can finish this up. Also ordered new strut bushings. Those came in yesterday.
