I have a 86 johnson 150 that was leaking between crankcase halfs. I split the case and spun crank to look at pistons and so. When I was done I noticed the there are 2 crank bearings kinda in the center of the case with what looks like sleeves over the bearings and there is what I think would be oil holes in the sleeves. Do those holes need to be in a certain place or facing a certain crankcase half when I put it together. Please help a dummy out.
