30p signature 4 blade (ET drag cut style) is a very good prop on an xb2002. Lots of bow lift, responsive, an top end.
I have a 225 promax with 2:1 gears on now. Next the 300x with 1.87 gears is going on it.
I have one but it makes a lot of steering torque. It was an RPM killer but good gas mileage.
I had the blades cut (semi hoss) and its a little better on torque.
