I now understand why no one has been able to get hinges to work with full range on a Moomba Max. After looking at moombas with factory hinges at the boat show they have a cut out around the hinge in the fiber glass. Looks like if I notch my fiber glass a little I can get the hinge to have full range. When the seat is fully closed the hinge goes back into the cut out. ca097588a18413d667a860b1a95f3078.jpg
