it's small power consuption, maybe The water was quite calm.. of course, your Torpedo propeller is certainly ideal for this boat
..it's interesting that increasing speed from 2mph on 4mph (exponent 2) increase power 6 time, from 2 mph on 6mph, (exp ~2.6) increase power 24 times !! If it's possible to find Torpedo number of RPM for each speed on this analisys? ..theoretical, power = Const* RPM^3
