The link I provided was to Grady White customer service. Since they built the boat I would think that's your best chance at getting schematics. This is a forum of people that own and enjoy Grady White boats. Did you click on the link I provided you with? Fill it out and at the bottom it asks "what's the nature of your request?". Type your request in the box. Or call them 252-752-2111. Good luck!
