    I have twin '95 V6 150 loopers.<br /><br />The port motor has a rattle at certain RPM's. (So does my transom door) Sometimes it's hard to tell where the sound comes from. <br /><br />Yesterday while out I knew I was hearing a rattle so I took of the cover, let the little lady drive and I went...
