I was removing some fishing line from my prop shaft when i noticed the seal behind the prop was loose. I removed the seal and water and a little grease or lube came out, so I decided to drain the lower unit. About two cups of water came out before I saw any lube. Could this be from the seal leaking? This is on a 1998 Johnson Venom 225. Also there are a couple metal o-rings inside the seal, are they supposed to be there? There is about a 1/16" gap between my thrust washer and the seal, should there be anything between them. Any help is greatly appreciated.
