i have an 89 mercruiser alpha 1 drive. when i pulled the boat i noticed oil pushing out the vent. bad winter this year and just took the drive off and had about a cup of water come out. just took the prop off and pressure checked it and the prop seal is leaking. just had siomeone do it 3 seasons ago . when i looked at it the lip is facing down on the outer one. from whjat i believe it should be facing up to keep water out. is that the case? i am not sure any thoughts or pics. thanks
