Ive been running a MW 14x19P (came with boat) on my rig with a 150 Merc XR4, no jack plate, and small gear case. Top speed loaded during summer months was right at 45MPH WOT at approximately 5400 RPM. I switched to a Laser II 13.5x22P that came with the boat topping approximately 50MPH at 4800. I know that 4800 is well below the power band range. Can anyone recommend the a better prop for my rig. I have posted this same information in the ProCraft page; however, there have been no responses. My numbers are estimated on my best recollections. Thanks
