I owned a 1997 31 open and currently own a 2003 38 Open and experienced similar problems on both boats till I figured out the filter just before the freshwater pumps was allowing air to enter the system.. I re-seated the filter cap using a new "O" ring which solved the iproblem.... Sounds like air is getting into the system....M2C
