Thanks for the info. I ending up installing a electric fan on the motor. That seem to take care of the problem. Got rid of the boat any way. Just got another Shockwave 26 again. Also got rid of Aquacraft Supervee 27R. What would be a good brushed motor and battery setup to use with the stock esc. Last Shockwave used Villian 550 motor and purple octura prop with 3 cell. Got approx. low 20 MPH. Thanks for the help.
