Engine Bilge Drain

Questions have been asked about the ommission of the drain opening at the bottom of the engine bilge. The correct answer is that there is not supposed to be one as this bilge is designed to contain any engine fluid that may escape from the engine including antifreeze, engine oil, transmission oil and diesel fuel. If engine fluid is allowed to drain into the main bilge below it will be emptied by the bilge pump overboard and this is not allowed.

At the forward end of this bilge there are 2 1" PVC conduits installed and fastened to the bottom the subfloor using fiberglass mesh, and the other end is at the bottom of the battery compartement. There are no breaks inbetween. These conduits are not there to drain the bilge.

Since these conduits have not been caulked some fluid will escape from the edges of the conduit when the fluid level rises enough. I place an absorbent towel to catch any fluid usually from the stuffing box.

To access the area for viewing, remove the floor board next to the galley and lower a small camera ino the 6" opening. I used a cell phone to take images and videos, so some may be sideways since there is only a 3" depth available.
