5s or 6s is going to be a handful. I don't think you will like how that hull will handle that power. Do you have the stock blue motor in there now? We have tested up to 45mm and 48mm 2 blade props. The 48mm gets the motor pretty hot so I wouldn't recommend it. The grim prop is supposed to be pretty good for a stock boat.
