Thanks Russell I figured out how to calibrate the speed. So I ended up going with a 2079 prop. Definitely helping plane out and hold speed constantly. Still can barley Jump toeside do to paddlewheel.. going to GPS.. also I’m not very pleased with the wakeboard wake... our 2006 Malibu vlx puts off very similar wake... 75 ft. 22 mph we ran stock ballast full. 850s in rear and 1000 in nose on the Malibu... I’m running 1,100 rear bags 425 nose bag. Hard tank center full and 1000 pounds of lead mostly in the rear to get a steep wake.. at 85 feet 23mph on the mojo also burns a ton of fuel...
