502, gen6 efi not even at full run temp. starbid Gil riser almost to hot to touch while port is bearly warm any suggestions what is cause of this or is that norm. Thanks

check for a blockage, check the water pump and make sure part of the impeller isnt missing and blocking a passage. hook a garden hose to the exhaust pipe water inlet and see if it flows ok like that.

Is this in the water or running on a water hose? There won't be as much water running on a hose and the left will be hotter. It will be a little warmer even in the water.

Thanks I'll try that this weekend and yes it is on a hose ,but the other motor's riser are not as warm. Thanks again.
