The basin wrenches are crap, and even pliers if you don't have two free hands to hold one pair of pliers and a large opening to work in. My center cockpit Morgan has the stuffing box down in the keel in the aft stateroom. It is difficult working in a narrow slot though I can sit cross-legged on the sole, leaning into the keel cavity as I work. After years of using crap tools for this job, I want to know the opulence of owning two good quality wrenches that will always fit the nuts perfectly, making it an easy and quick job of adjusting the stuffing box.
