As part of year maintenance, I had dealer replace the water pump. I went fishing for first time after maintenance and the water pump shows 9 psi when the engine is shut off, at 5500 rpm’s it show 25 psi, slow down to idle water psi drops down to 9 psi, shut off engine water psi remains at 9 psi.
What is going on and how do I get the problem fixed.
Thanks
Mark
