guys im in desperate need of some help. i just replaced the water pump on my 15 hp mariner and it is still acting up. i replaced the pump because it was only peeing at idle if i got it up on plane or gave it any gas at all it quit peeing. i changed the pump and still the same problemm last time i changed the pumpi didnt have this problem and the old impellar still loked good. im thinking that the pump is sucking air or not getting the water up to the motor that it needs at higher rpms. any advice would be greatly appreciated.
