78 sceptre onboard prop removal

[fredetzel]

I had the boat out last week and everything was running great until I hit a submerged log and bent my prop. So I made a puller out of 3\16 steel and some 1\2 inch bolts ,I removed the prop nuts and noticed the key is sheared and the slots are 180 degrees out. I tried the puller but the prop won't budge .Anybody ever had this issue or know how I can get this prop off,any help will be appreciated.
Thanks
Fred
