help with bearing housing removal of lower unit on 115 v4 1977 unit

[crankbait cowboy]

i took the 4 bolts out from inside as the book says and sprayed it down with penatrating oil last night. then this am i used some threaded rod and harmonic balancer puller as book states, and ended up stripping threads on rods. then i used 2 8 inch bolts on puller and got it so tight i could not use a socket to turn it.so i grabbed the air gun and gave it short bursts with some tapping on housing and bullet case with rubber mallet between bursts. after about 4 bursts and tapping between one of the bolts broke and left part of bolt in bearing housing for me to easy out out of there. good news is the threads in bearing housing are holding , bad news is the housing has not budged. Ideas or suggestions???? would some heat help or be a real nono? i plan to replace the seals and o ring so am not concerned about damaging them. any help or suggestions would be greatly appreciated.

If you used the same holes where the 4 retainer bolts came out of it will never come out as your pulling washer against snap rings, you want to be in the carrier itself. I use a puller to pull carrier with the prop washer in place to hold pullers arms tight in housing...

no, i am using the" two threaded holes in prop end of housing. 5/16" and harmonic puller on prop shaft, as the manual states

Heat housing with a propane torch with map gas

You may have to use a hotter torch.

shes out!! may have got a bit lucky. i sprayed it down good with penatrating oil and went after roosters in south dakota for 4 days . plenty of birds , killed a few but no worries missed plenty for seed. when i got home i used the harmonic puller and short bursts with an air gun. i would tighten it down back it off and tap it and the housing then do it again in short bursts. after about 4 times of this lo and behold it started to move kept going in short bursts and it come out. think i got a bit lucky as no heat needed. thanks for suggestions to all.
