cooling issues?!

[thaclone]

hi guys
I'm pretty new to boating and I jsut got my M41
totally awesome

but I might have an issue with the cooling of the ESC and motor.
today I was running my M41 for about 20mins until the LiPos where empty ^^
when I unplugged them I touched the motor and ESC and they were both hot... I could not touch without nearly burning my fingers

I always check if water is coming out of the side and it was, so the water was running through the pipes and stuff

but why was everything so hot?
I drive RC cars, too, so I know that this stuff can get really hot, but I'ver had it this hot before.

Only thing I can think of right now is, that the water was to warm, to cool it down - it has about 28°C / 82°F

Do you have a dual pick-up rudder? If running lipos this is a must
