Took off foot and water pump looks good. No water coming ou of peehole on back of motor. None at top of heads. Hooked water hose to pipe coming from water pump and water comes from bottom of motor down through mid section. Are there any freeze plugs under the powerhead? What can i do to figure out this problem?
