As rigged, our Mandalay topped out at just over 30 mph turning a 17-inch-pitch Yamaha stainless-steel prop at 5,500 rpm. Best cruise was slightly under 14 mph, where the Yamaha burned fuel at 2.8 gph, netting just shy of 5 mpg. At that speed, the Mandalay is skimming along nicely, giving a solid ride with little banking even in tight turns. Of course, the boat still runs at an economical 7.2 gph (at 2.75 mpg) at the more fun cruising speed of 23 mph. The RPT pontoons give good lift without making the ride unstable.
