I just put my 79 challenger on the water for the first time. I got the boat knowing the was a problem with the motor, I had it pulled and fixed and it runs great. I took 1 trip around the lake with no problems then while idling in I noticed the motor heating up I looked in the back and no water was coming out from the thermostat outlet hose in the back of the transom. I just had it hooke up to the hose before taking it out and i had no problems with circulation. The problem has go to be with the pump or a clogged intake hose. I am waiting for it to cool done before I start diagnosing it. The question i have is my pump is a jacuzzi yj, I know they operated a lower pressure but it should put enough pressure to circulate thru the block, right

? Someone suggested the maybe that pump needs to be ran with a water pump but that dosent sound right. While @ 3k-3500 RPM arount the lake I had no temp problems. Any ideas

?? Thanx in advance..
