This little problem has now go me to a stage whereby I am having nightmares about it... 
Fresh water finding its way into bilge...
From behind the stern tube the rear (Battery) compartment... Dry as a bone... I have climbed under and checked every piece of the hull inside and its bone dry...
This was after I had sealed myself the scupper tubes, and the inspection hatch and the rod holder which previously emptied water straight into the bilge..
The main engine bay... Again, the bay is freshly painted and any signs at all of water running down the sides to the bilge itself would be evident.. It is bone dry, this was after I had sealed myself the side draining points from inner hull to outer hull. No water signs at all insie the locker to the side, nor the under deck compartments, nor along the stringers... In fact 100% happy that no water at all is entering from rear of cabin to bathing platform..
Inside.... Have removed the front cover under seat and checked where bow thruster motor is... First time I checked this there was fresh water in there... This could quite easily have been overflow from engine bilge... Dried this out and checked sides of hull... The sides are all covered in dust and again no signs whatsoever of water ingress..
Climbed into locker under the floor (Under seats(, removed both side panels... Again, no signs of water at all and dust up the sides so water running would be evident.
That as far as I am aware only leaves an act of god... So, as I dont know the guy or have ever had dealings with him, he is unlikely to answer my when I say "O God, where the f**k is this coming from"...
Anyone here any ideas?
The bilge stays as dry as a dry thing all day long.... I get in, I wash down, i check bilge and there is water... I can drink it so its fresh... It tastes of soap suds, so I know its mine... where.... I have spent 3 weeks now trying to find this and I would be so bold as to say there is no way it can enter.. But it does.!!!!!
Anyone??? It will stop me going mad...... 
Cheers
Dave
PS: After a "normal" washdown, wash with soap, then a good hosedown, there is about a litre of water....
