      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.

        I believe they are 1/4" – 20 threads per Inch (SAE standard coarse) should be grade 8 . . . 😀

          thanks for the tip. did that with a harmonic balancer puller and impact gun. no dice. she wont budge. I can see how having the OMC puller will perform much better and was thinking about buying one, but the local shop said he would do it for less, so I am up in the air.

          anyone have ideas? i did watch a few videos and read this thread again. but the OMC puller has the right height on the bolts and probably centers easily.

            The OMC puller is an excellent tool and completely worth buying if you plan to work on these engines very much.

              Ben is spot on! It takes me longer to screw the three shoulder bolts into the flywheel than it does to pop it off! Done.

                Based upon my experience, which wasn’t very good even with the OMC puller, if a local dealer offered to remove my flywheel for less than the price of a puller, could guarantee its removal in one piece and no additional fees, personally, I’d go for it.
