So I'm chasing down what feels like secret levers on my '98 Grady 228, the hidden push-pull stuff I can't see, and it's maddening. Now I notice both battery bay hatches just forward of the transom have a steel rod with a ball on each end. What do they do exactly? Maintenance access wasn't exactly a 1998 design priority, so I'm bracing to grab an endoscope to see what's actually going on???
