Thanks for all the input guys.
I went for the 3 bladed flexofold 17X12 prop. The size was a recommendation from Flexofold after I gave them all the stats for the Maverick 400. I am very happy, the prop looks well made, I have no problem going in reverse either. The prop has great thrust, at just over 2000rpm I am doing 7.5 to 7.6 kts. I still have to check the max revs but have got to 2900rpm with no problem. I am pretty sure I will get max
rpm of the
motor when I try.
