18590 self-priming macerator runs, pumps waste thru the hose to the thru hull
. I disconnected the macerator hose from the thru hull
and pumped waste into a bucket thru the hose connected to the macerator. The thru hull
is clear. I have disconnected the hose from the thru hull
and opened the thru hull. I can see daylite and water
runs into the boat from the thru hull. When the hose is reconnected to the thru hull and the macerator is run nothing come out the thru hull. I have snorkeled under the boat while the macerator is running and nothing is coming out. My thought is that there is not adaquate pump pressure to overcome the outside water
pressure. Any thoughts.
