    Don’t despair…… years ago   my Merc 45 classic drove me nuts  …

    the inflow of water to the  impeller pump  was being blocked by a ” floating grommet” found  BELOW the impeller  housing  in the  LU cavity. !  How it got the  remained a mystery till I sold it 🙁  Fantastic engines those  4 cyl Mercs )
