Hi everyone,<br /><br />I changed my water pump several months ago and I recently took it out in the lake. When I got back I noticed that drive oil was leaking from my two weep holes on my outdrive. It was a very slow leak so I didn't think much of it until I noticeed a puddle of drive oil on my garage floor. I went to the MErc dealer and talked to a service writer who didin't seem to kow very much. He said that possiblyI did not change out a small o-ring in the out drive. When I dropped the lower end I noticed that indeed I did not, the o-ring was missing. Could this be the root of my problem????? How do I completely remove all the water form the lower unit? Is draining the oil from the outdrive sufficient enough??? Any ideas let me know please???? I'm heading to Lake Meade<br />on Thursday and I need to get this problem fixed.<br /><br />Thanks,<br />Dan
