Re: 7.5hp Cranks OMC

Chris, it doesn’t seem that way, it is that way! On the 7.5 anyway. These cranks from Pine Lake are used, but I understand what you mean by too much money in old motors. If polishing cranks, do you haven a micrometer? I’m sure someone here has the journal size spec. You can compare to the bottom journal to begin with. Needs to be real close (.001 or less) this is not an area where a little more space helps the rod get a little more oil. These little bushing rods do need the 16/1 oil ratio for sure. I haven’t had much luck saving one of these cranks, but it sure can’t hurt to try.
