I have a few questions concerning the Aquacraft UL-1 Superior

1. What is the max S Lipo I can run with everything stock?

2. Will a different water jacket help improve cooling with the stock motor?

3. Whats the best prop to use for my Superior?

4. If I upgrade the stock ESC will I have to upgrade the motor as well and if so what ESC and Motor should/will work with the UL-1 superior?

5. Lastly what else should I be aware about this boat and about driving for the first time as being a beginner to RC Boats.
