Mine is rated at 650, but one time I had 900 (before new wear ring and impeller) and it took a half mile to plane. After the new wear ring and Skat-trak impeller, it would pull us all out on a plane in a couple of seconds.
But, it was VERY crowded with 4 200 lb people in it (3 of us over 200).
Regardless, it is a Federal Coast Guard rating, and you will be ticketed. Then they will get you for the lack of life jackets, the empty beer cans, etc. etc. :cheers:
