Tried a few more props 13.25 x 19 Rapture 3 blade cupped 36.5 mph at 5800rpm 13.5 x 18 Raker 3 blade 36mph at 5900rpm Never tried a 3 blade with jackplate but is night and day with 4 blade vs 3 Blade 3 blade had way more slip despite cupping 13.25 x 18 4 blade Turbo worked well 38mph at 5750-5800 with better hole shot, but not as good top end as the 13 x 21 Rogue 4 blade 40.5 mph at 5400-5500rpm. The Rogue runs lower RPM though. There is always give and take with these props Do I want top end? Economy? Hole shot? Going to try the 13.25 x 20 turbo might just dial it in! Still have the Rogue 13 x 17 for heavier loads and sick hole shot. We shall see.
