Very few gearcases have a 5/16" diameter hole above the bushing. I found that out when somebody broke a gearcase by pounding a 5/16 rod through it anyway. As time went by, I found that the hole diameter actually varies all over the place, and I kept turning the diameter of my tool smaller and smaller to go through the smallest known hole. The last spec I used was still a few thou’s larger than the OMC factory tool. Ultimate result was that it got to where it didn’t work reliably. And the factory tool doesn’t work reliably either. So that’s why I stopped making them. You can read about an alternative way of removing the bushing at my website, http://www.franksoutboardtools.com
