Dont know what prop Kelly is running but a heavy boat at 74 at 5800 rpms is pretty impressive that would be in the theroy of a super good 25 pitch prop or a 27 Tempest.Just never know what loaded means 5 rods and 3 planos is loaded to some and 500 lbs of tackle is loaded to others.797 we saw 77 every time and it was loaded ,5 rods 4-5 boxes and 10 waters lol
