Hi all,I just got back from a week of fishing,checked my gear oil to find milky,figured the 2 seals should be replaced due to fishing line wrapped behind prop,pulled the hub out and cleaned to ready for instalation,noticed paint crack above where the prop is where gear case gets thin and meets the flat part(will try to post a pic)the crack is about 1 inch on both sides,sanded the paint of to see if it was just paint cracking,but looks like a hairline crack.Can this be welded? JB welded? Shouldn't oil be leaking out if it was a crack? TIA
