Need help with excessive motor heat

[slowsl]

Any updates on this? I am having a similar problem with a 3650 @2750Kv with same esc and a X438 prop. Battery is 4s nano-tech 2250 65-130C discharge. Hull is very wet however, not an outrigger. Motor got very hot after only 2 minutes.

Unfortunately the motor is just not a good match for a 4s battery and a boat wanting more than a 1.5 to 2 minute wide open throttle run. I also would think it would be no good for SAW, overpropping it would just shoot up the amp draw and give little mph gains. I've also learned that Leopard motors are not nearly as efficient as an equivalent Neu motor, or other higher end motors. I'm still fairly new to electric boats, so take what you want from this. The 2750kv motor is turning over 40,000 rpm, should be 28,000-34,000rpm. I think this spring I am going to grab a Leopard 3674 and shoot for an rpm in the appropriate range for heat racing.
