I would like to modify the impeller in my 1998 Sea Doo GTX limited. Im interested in getting more top end speed. The only modification so far is a high compression head and intake grate. I'm planning to put on flame arresters in the spring. Ive spoken to a couple of dealers for modification parts and I am not getting very clear answers. Can you guys help. Thank You Jim
Hi Jim, Your stock impeller is a stainless steel 14-21 progressive pitch. (14 is bottom-end, 21 is high speed). We do offer a impeller performance modification that will give you a little more speed for $135 which includes rebuild.
