If you intend to fish rough salt you probably do not want a flat bottom sled. It'll beat the crap outaya. Get something with maybe 12 degree at bow, and 4 at stearn. If you want to get shallow in the rivers you better get a jet. And remember you lose about 30 percent of your horsepower to the jet pump. So an 85 hp motor puts out 60 at the pump. I'm not an expert by any means. But, I hope this helps.
