Hello all, we are planning to haul our 1974 GB36 classic in October for hull cleaning and bottom paint and a few other things. While its out we would like to have the Cutless bearings replace.Our boat has twin Lehmans and the shaft diameter is 1.5 in. My question is what size Cutless bearing should I buy, I can't find what the outside diameter of the bearing should be. Any help would be appreciated, Thanks
