On the calm Intracoastal Waterway, the 26 cruised quite nicely at 31 mph while moving 14.2 gph through the twin, four-stroke 150 hp Yamaha outboards for economy of 2.21 mpg. The Jupiter hopped up on plane very nicely with 150s, but you can also order the boat with a single 350 if you want extra horsepower. With that package, it's about 112 seconds faster out of the hole and 3 to 4 mph faster at top end. With the twins, top speed hit 48.7 mph at 5,900 rpm using 32.6 gph total. A single 150 was incapable of lifting the hefty 26-footer onto plane, however.
