I have an 86 ericson 35-3 and I am trying to replace the shower hose. Does anyone know how to access the fitting behind the shower panels? When I remove the escutcheon plate , there is just solid plywood. It appears that removing the right side mirror may give me access, but maybe there is solid wood behind that. Before I start drilling out the wooden plugs, maybe someone has run into this and might save me unneeded work----Also, does anyone have or know where to get blueprints for the boat-----Thanks--Jim
