New To Board w/ Question

Great board for owners of a great boat. Recently purchased a 1991 V-20 cuddy w/ a 175 Merc. from a lady whose husband passed away. Boat is in great shape and seems to run ok. I would like to find some info on this boat. Where can I find an owner's manual or specs. I e-mailed Wellcraft but got no answer. I don't even know the fuel capacity. Thanks and looking forward to talking with you guys. I live in Virginia and fish the Chesapeake Bay. Happy Holidays
