Leaking oil near prop

[Craigums]

I noticed i'm leaking oil near the prop and two screws that hold on the plate that my prop sits on. I imagine there is a prop seal in that area causing the leak. I would like to get it fixed before I take my boat out this summer. I would like to try to fix it myself if its not a major job though. Does anybody know where I can find a parts breakdown or schematics for this motor? Im also not exactly sure what year it is, I think its from the 80's. Any help would be much appreciated. Here is a picture of the motor, I will also try to get a picture of the prop and leak when I go to my cabin this weekend.

What color is the discharge? If it is dark and smells a bit like gas it's probably unburnt gas / oil mixture.

It's like a coffee color (oil mixed with water?). Not real black like oil im used to seeing and not that yellowish color the lower unit lube I just put in has. I wish I could get more pictures sooner. I know im not the best at being descriptive. When I get up north to take the pics, I will smell it and see if it has a gas smell

If you can let us know the model number, we can tell you for sure, but it looks to me like a 1984.

Changing the prop shaft seals is not a very tough job, depending on your mechanical skills. Drain the lower unit. Those 2 screws you mentioned need to come out and the bearing carrier removed. A 2 jaw puller works good here, but you can also do it by gently rotating the carrier enough to expose the "ears" that the screws go throug and GENTLY remove the carrier. There will be 2 back to back prop shaft seals on the end closest to the prop and an o ring on the other.
