Hello..I have scoured the forum looking for help with a friends outboard. We changed the impeller and checked the tstat because of an overheating issue, however when it came time to put the lower unit back on, the gearing was all screwed up. Could not shift gears smoothly...very hard to shift. Did nothing else to the lower unit. We managed to re-connect the clutch rod to the horizontal assembly with great difficulty but now we cannot shift the gears. Can anyone help us out? Thanks
