Access to the back side of my engine is through the starboard cockpit locker. This access is important because it’s the only way I can get to the propeller shaft and stuffing box. Once or twice a season I have to adjust the stuffing box so that it drips the correct amount of water. Not too much, not too little. That drip lubricates the prop shaft. Too fast a drip makes the bilge pump run too often. Too slow a drip damages the prop shaft.
The batteries are also down there just to my right in the photo. I think I was checking the electrolyte level on this trip into the locker.
It is always an exercise in flexibility, made more difficult by my increasingly inflexible body. Thought you would enjoy this photo my wife took of me emerging from the nether regions of the engine room.
