A 2 stroke V6 200 should be fine on that boat. Like Rick said, a lot of these boats were delivered with 200 outboards. As would some of the newer, lighter 200 HP 4-strokes, like the new Suzuki 4-cylinder 200. A 3 liter V6 will give you plenty of torque and top end - you may need to experiment a bit with props. Are you looking to buy a new mota, or go with pre-owned?
