Salty,
The number is 70017PII-02. It is a Poly-guard material and it worked very well night before last in a heavy down pour that we had. I do feel that I need to add a pole in front of the console due to a small pocket of water building up at the front rail. I don't know what the cost would be because I traded in my cover for the 170cc with the boat when I purchased my skiff, so they gave me credit for that one.
