This summer after changing my lower unit gear oil I noticed a small drip of oil at the bottom drain screw. I drained the lower unit and pumped new gear lube. I installed new Yamaha gasket PN 90430-08020. All was fixed...So I thought. I drained it but this time replaced the the old drain screw and another new washer as well. I made sure I rolled gasket in the oil before installing. Again made sure no old part of gasket was attached to lower unit drain screw hole. Again today it has small leak at the bottom screw. Motor is 1997 C90TLRV Yamaha Outboard. Any thoughts?
