    Default 2006 Evinrude motor 40hp 4 stroke

    Have an Evinrude 40hp outboard 4 stroke... today while driving it, it started making a continuous loud clunking/knocking noise... when put in reverse the knocking went away but when back into forward it started the continuous loud knocking/clunking noise...any idea what this might be?
