Prop size for engine/hull?
Octura X472 ,X670, are good props for 23cc You guys are pushing big boats with relatively tame motors.It will be tough to swing a full 280. The P275 is probably your best bet,the Octura's will get you a little more RPM
Twincraft with a pro mod is a good setup,,,you might wanna try that P767/3 from Octura......good luck guys....STAN
