Take off the water cooling hose from the rudder and blow into it., you need to trace where its blocked.

Sometimes the nipples in the motor cooling jacket are clogged with the sealant that is used when they screw them in. The same thing happens on ESC's too.
Use a drill of the appropriate size, that fits in the nipples, to ream them out, including the one on the rudder. Just do it by hand not in a drill.
