Starting this project myself and this thread has been very useful, thanks. Can you tell me the nut size of your flywheel? I have a 59 Gale I think has them same size and I cannot find it listed anywhere.
I am going to use a harmonic balancer puller since I have a good one laying around. i noticed the lag-style anchor bolts the OMC puller has are lathed on the bottom so they screw in right for a sure level puller. that seems like a hefty advantage, honestly and worth a buy for the next time.
I intend to take it slow and make sure to tighten the puller bolts snugly and evenly manually first and keep a close eye.
also – making sure the correct thread size for the puller bolts are 24 NPT.
thanks again.
