Hey everybody...sorry that im posting this is in the gas forum but barely anyone comes to the electric one so please help me out...i have a 19 turn motor and usually i run 5 laps in a race...always on the second lap my boat stops because one of the motor wires (plus) keeps unsoldering because of high temperatures on the motor head...my wires are slodered directly to the head. I have a cooling coil for the body of the motor but i guess thats not enough. Whats the best way to cool a head without fusing anything up (i.e. if i attach a metal tube to both of the places (i dotn noe wut they are callled) where the wires are soldered and if water passes thorugh the tube wont it short someting oput?) please help me and also is it possible to cool botht he body and the head if my intake hole isnt that big. plz help...thanks

if you're running that hot, you might want to drop down a size on your prop.
