Definitely too small but you already learned that by how it didn't perform. I believe rule of thumb is 1" for every foot your board is, so at 9'2" you probably want to go with a 9" single or maybe an 8 like Bassplayer has
I couldn't ride mine with just the 8'' rake, but with the side bites it loosens the board up and is so much fun. The 9'' is for going straight and noseriding. You really have to work hard to get all the way around on a cut back.
