    The wear plate for the impeller has to have a good seal on the gearcase, or exhaust gases will greatly effect the water flow. I recently had this issue on an old 18 and found that the wear plate was not sitting flat on it’s seat correctly. I cleaned both surfaces really good and applied a little sealer and problem solved. It pumps like it should.
