I am looking at a possible upgrade. I really like the layout and look of the 90-91 270 DA. This is a 28'7" boat, 5800lbs, & 9' beam. I know twins would make for easier docking but I like the thought of only one engine to maintain. Will I be satisfied with the 7.4 - 330hp in this boat ? I like to cruise just on plane (3000rpm & 24mph in my current boat) and pull the kids on the tube sometimes. thanks for any input.
