I have a 1975 32 CC O'Day with the Atomic 4 (oh it purrs) problem; I am on the hard right now doing some much needed maintenance. I am having a hard time trying to remove the prop shat, can't get the shaft to come out of the output coupler, I broke a bolt but drilled it out still won't budge heated it beat it! Any suggestions? also it you have the specs on the shaft ie; L, dia, etc I may have to cut it at the coupler. Help! JIm
