I,m using the 6800kv in my mini v with the 25 amp speedo it came with there is no lack of power but the can gets as hot as the motor in my brushless mini lst and that truck is all alum. So I think I,ll make a water jacket for the motor and a water cooled block for the esc and see how cool that keeps things.I,ll keep you posted as soon as Iget the chance to build it.
I hope your water jacket works out, keep us posted. But I don't think its going to be enough too keep the motor cool if its getting that hot. Here is my comparison. I had that same motor in a smaller boat and it got smokin hot. And that means that no amount of water cooling will keep it as cool as it should be.
