32mm 2 Blade Aluminum CNC Boat Prop (P1.4/2x2)I broke the stock plastic prop on my Centurion a few weeks ago. While the boat came with a spare 30mm plastic prop, I got a couple of those 32 mm aluminium props. I just slapped it on the shaft. Had to move the drive dog as far forward to have enough thread to put the prop nut back on.
I'm not sure boat is any faster but if felt more stable at top speed. Battery, motor ans ESC didn't feel any warmer than with the stock prop.
Good purchase in my opinion. Haven't found the stock 30mm prop on HK anyway ...
