You should have a plan
Good idea on the A/C drains. Now that I have some of my larger work done, I am going to start doing as you suggested and hunting down these little drips and drops with the goal being a dry bilge.
I am going to be on the boat for the next five days or so, and will have an opportunity to look this stuff over.
The bilge on your boat should be dry.
It will remove smells from the boat, and make a big difference.
First item is your prop shaft.
Honestly, what I would do is invest in a dripless stuffing box. They are wonderful.
I had one on my 40.5, and not one drop of water
My 49 has one, and same thing. You will never need to think about it ever again.
Next thing is to plumb your airco pans into sump boxes, or another way of draining them overboard. Airco units put a lot of water in the bilge.
If you want to know the really, really, right way to do it, here goes :
Get a Whale IC grey water pump with T fitting.
Drain your showers & aircos to it.
You will have a maintenance free grey water system with no filters, etc. It will just work 100% reliably.
Your bilge will be dry, and you will have reduced on board smells dramatically
