I have a 2000 322 Cruiser powered by merc 5.7's. I am getting water back into both engines intermittently. I have checked exhaust flaps any they are in good condition, however I think the water line is sitting pretty high in the y pipe. Can anyone with this model regardless of the year have the 3" spacers installed between the manifolds and risers? I am concerned they may have been eliminated by someone who didn't know what they were doing prior to me owing the boat. Any input or any other possible solutions would be great insight.
