Hi, I recently put a new impeller in my 40hp Mariner, its a 1989. I put the impeller on the shaft and turned the shaft clockwise and the impeller went right it. Was this right? Once I started the motor up, I now of know water pumping out. I pulled the pisser hose off and had not water in it at all and none coming out where it is connected to the motor. I also pulled the brass plug out of the water jacket cover on the rear cover where the spark plugs go, and again nothing. I did notice that I have water leaking out of the right side of the water jacket next to the spark plugs and I will be replacing the gasket on the cover.
My question is where should I start to figure out why I have no water coming out. Could the leak that I have in the cover be sucking air and causing there to be no flow???
