ok, i should have spent more time reading the cooling system section of the manual,, i see that it flows from the tuned pipe into the engine and then out thru the drain hose at the bottom, if for some reason im still overheating i may have sucked up sand and will blow compressed air thru the drain hose on the bottom of engine?? if that dont work ill remove the tuned pipe and see if i can find the blockage.. replace with new gaskets,, any other suggestions are appreciated,, going to launch boat tomorrow morning and see whats going on,, thanks all
