Two words.Cat and Skater.If you want to go faster on less horse power,get better gas mileage,and handle the rough better,get a cat and the best cat out there is a Douglas Marine Skater.If you want to go one up on that then put a couple of Merc outboards on it.Everybody has good advice here and I espeacialy like having a boat load of cash in hand and going low ball when you first see the boat.Good luck.
