I had intentions of checking my lower unit oil and accidentally removed the screw located near the water intake thinking the screw was a vent. I immediately put the screw back in once I realized my mistake. I understand that this screw holds the lower drive shaft bearing race in place. Did I mess anything up by removing the screw? Could removal have caused something to slip out of place needing to be checked before I take the boat back out? Thank you for your expertise and response. 1989 Evinrude 150 VRO. JG
