First Of All Let Me Just Say I Am A Novice At Boat Motors. I Have Recently Obtained A Really Nice Merc 5-hp Motor. It Was Recently Gone Through From Top To Bottom Before I Purchased It. However, After I Took It Out For Its Maiden Voyage I Noticed A Fuel Leak. It Appears To Be Coming From The Bottom Of The Cylinder Block Through The Bleeder Tube (according To My Schematic Breakdown). Any Ideas On The Cause And/or Cure????
