Location: Elk River, Minnesota | all you would need for rebuild parts would be the impeller and key, along with the gaskets for the housing. For a little more, you should be able to get the whole housing as well... Shouldn't be too much $$ for that. As for taking off the lower unit, I don't believe you would have to worry about any seals. If the design is anything like the 2 stroke model (I am not sure on this...just going off of what I know about my yamaha), the shifting shaft is a slotted end similar to your prop shaft. So..when you unbolt the lower unit, it should just drop out of there. The only thing you might have to unhook from a joint is a speedometer tube.
Once the lower unit is off, it is a matter of a few bolts, cleaning up the old gasket material, and reassembly.
One thing to look out for, though is when you get the lower unit out, there might be some small shafts (they look like shelf holding pegs) that will help to align the lower unit to the mid section Sometimes they are loose and fall out, sometimes they are solid on one part or the other. Nothing to major of an issue, just something to pay attention to when you disassemble.
If you attempt to do this by yourself, you might want another set of hands as you remove the lower unit and reinstall...those things can get a little heavy, and definitely ackward to handle. So long as everything lines back up, water tubes, shafts etc...that should be about it.
