sweet thanks, do i spray wd 40 through the cooling lines? or right into the motor where the coils are, or both?
No need to do anything with the cooling lines-- the job of the cooling lines are to pump pond water into the water jacket and cooling plates on the ESC.
Your motor will work fine when dry, but using corrosion X can help extend the bearing life. I have an OPC tunnel with an exposed motor, so every time it capsizes it is under water (which is about every time I run it!).

PS, motor bearings can and should be replaced periodically
