well I have to replace my brass sea pump on my 2003 merc 496 mag. I was just with my mechanic and he said that some one in havasu is modifing the pumps so they will not get grooves from the sand in the brass at the top and bottom of the impeller. Has anyone heard of this and or know of any other alternatives? I have the pump that has the pressure sensor and does not have vacume lines.
thanks
