Black Jet stream ride sponsons

These are sponson that are mounted to the side rail of the boat.  Help with stailabilty and turning of the boat in lakes and open water. like turn fins of a jet boat as seen on jet skis and other water craft. 
Installs to the bottom rail using the 3 rear screws in the edge when flipped over. You will need to trim back the edge protector to install these.  
Recommended to use bigger screws to install the sponson, 3mm or so screws for better attachement. also E6000 or shoe goo as well with the screws to make a better seal and attachment.  Mine personally Shoe goo mine just for extra asuance during install. 
 
Made from nylon to be durable.
