Hey all. A buddy of mine wore out the upper gears in his 4.3 Cobra lower unit. We are weighing the option of swapping out the gears versus replacing the upper half of lower with a used unit. Since we do not have a machine press, switching gears is near impossible. My question is this: I know that the upper half of a 3.0 cobra would fit on this lower unit, but I believe they have different gear ratios. What effect, if anything would that have on the unit? Would that work, or would other gears have to be swapped out to make the ratios match? Thanks!!!
