This is a package of 2 brand new Exhaust/Muffler gaskets that will fit the Aquastar 26cc to 29cc Marine, 2 stroke motors as well as many other similar size motors. They are slightly thicker and larger than a normal muffler gasket for much longer life and to avoid tearing. Made of high temperature 1/32" automotive grade material to last a long time and avoid any leaking. We also recommend a drop of threadlock on the screw threads as well.
