I have a 20hp merc that leaks gear oil when you leave it proped all the way up on the latch for a few days. It is a black and blue tiller motor that I rekon is mid 70's to early 80's though I don't know for sure cause there is no S.N.. I'm guessing it's the shift shat seal and wana know is there any other seals I should replace when I'm in there? I have never had a lower unit apart before so I don't really know what I'm getting in to. How difficuul a job is this, are parts and peices going to go every where whrn I pull the foot off?

Next we have a 1970 merc 110 9.8hp that I just rebuilt the carb and fuel pump on and it runs great! But....... now it's not peeing out the weep hole So I guess I gota put an impeller in it. Same deal as above, what am I getting in to?
