Take the engine cover off, then remove the back floor panel. Run the engine and get down and watch....more than likely you will see the culprit immediately. My guess is the muffler has a crack in it where it meets up with the long straight hose that exits out to the flappers. Could also be the shaft log seal or the thru-hull exhaust fittings out the back. Also check the raw water intake ( from bottom of boat, there is a screen) or finally one or both of the fittings for the Speedo tubes. If you can stop the leak or change the sound by pressing down as you stated, my bet is the muffler....
