THIS AUCTION IS FOR A "USED" MARINE EXHAUST, THIS WAS RECEIVED FROM A MAJOR BOAT MANUFACTURER AND I BELIEVE IT FITS ON A FOUR WINNS JET BOAT. ITEM IS IN GOOD CONDITION, AND MAY BE NEW, BUT IS DIRTY FROM BEING IN STORAGE, SO I AM LISTING AS "USED". PLEASE LET ME KNOW IF YOU HAVE ANY QUESTIONS AND REMEMBER TO LOOK IN MY EBAY STORE FOR MORE HARD TO FIND BOATING ITEMS.
