I am new to this site, so I appoligize if this question has already been asked. I have a 2000 Sportster LE with the single 951 engine. The boat runs great, about 52 MPH when I am by myself. I want to pull 200 lb.+ water skiers, but I am having trouble getting them out of the water. I see a lot of people change their impellers to help solve this. I am looking for positive and negative feedback on different manufacturers and pitches of impellers that people have tried. All suggestions will be appreciated. Thank you. Joe
