I have a 1990 Superjet with a 650. I also have a 1994 Superjet bored out to 719 with a Riva Red pipe. I currently have a Hooker 10/16 in the 1994. I would like to put the Hooker 10/16 in the 1990 stock 650 and upgrade my impeller in the 1994 . I am looking for advise as to what would be a good upgrade . I don't care about speed , only jumping waves and fast acceleration . Thank you .
