This Heavy Duty Rear Exhaust Hose replaces the expensive and prone to fail OEM Yamaha Hose. Constructed of braided 4 ply polyester hose, the Black Mamba virtually eliminates collapsing and overheat issues associated with the OEM hose. The Black Mamba's flexible construction makes it the preferred choice for all aftermarket hull and motor installs due to its ability to contour around limited engine compartment space. Replaces OEM Part Number: GM6-67555-00-00
