Access to Packing Box
Even with the boat out of the water, my bouts with the packing box were not fun. When I had to do a prop strut replacement, I figured some room would be nice, so I did a quarterberth cutout and it makes stuffing box work almost enjoyable. I was concerned that I was weakening the structure, but it's been several years now and I don't see any problems. My cutout is probably bigger than needed for just stuffing box work, so that might simplify things for you should you make an opening. I had no idea what I was up against with the prop strut, so I went big. And since I planned on using the cutout piece to cover the opening, I only had one shot at it. A sketch is attached. If it isn't readable, I can send it direct if you are interested. This is all assuming your quarterberth is the same as mine - I have seen some variations in the E27.
