I'd highly recommend the Robalo R227 Dual Console with a 200HP Yamaha. Great solid well designed deep-v outboard boat. Perfect for the big lake. They recently had one in stock at Melvin Village Marine. Not sure of the price or your budget though! Here's a link:

If you can find a used one from a previous year, you could save a bundle. Best of luck with your search
