I took off the lower unit to replace the impeller and put the lower unit back on and it goes in neutral and in gear but takes some force to put back in reverse gear. I took it off and placed it back on trying to line up the gears a few times but still get the same thing. The lower unit is in neutral when I take it off and the top is also. Im pretty sure its just me not being able to line up the gears. Any tips on how to line them up easier or could anything else be wrong?
