I'm new with boat talk & names of things.Please,bare with me.
Do they make a complete replacement seal kit for the sterndrive?
I found that I'm leaking 80 weight oil under the engine area I think it's called the Haul or hull .I'm also,dripping water inside the hull.Not much dripping.But,enough to be worried.It don't seem to leak water when I'm moving.Seem's only when parked seating in the water not moving.Leaks enough for the pump to pump out.Gives me the red flag to start working on this problem.
Some say it's the big rubber hose that the drive shaft goes into.But,won't really know until I tear it apart.I was thinking while I'm tearing it apart may as well replace what seals I can while I'm in their.To make things easier & more simple I was hoping to find a complete seal kit?Do they make such a thing?

As for the oil leak,Is there just o-rings on the drive shaft causing this to leak oil?
I see seal kit's online but,seems only flat gasget kits not O-rings or the rubber hose boots.
Thanks!Dan

For the Bellows - if you're in there, you should replace them all.

For the Alpha 1, here is a link to an upper seal kit:

If you haven't done so, and don't know the last time it was done, a replacement impeller is a good idea:

I *think* these are the correct parts for you. You should really verify on your own, however.
