[Public-List] Stern tube

I find it very difficult to determine the location of a leak with the 
boat out of the water. Get a good flashlight and take as close a look as 
you can. Look for wet spots and then look above them. Be patient.

In my case, I had failed to completely caulk the upper bolt holding the 
cutless bearing housing. I saw a water droplet on the end of that bolt.

Sometimes I've used my phone to take videos of things I couldn't see 

When you've found the general location, clean it as well as you can and 
wrap a paper towel around it. See where the damp spot is.
