I am going to take on the task of replacing my wear rings and possibly both impellers this weekend. My question(s) are for those of you guys who have done this already which impeller did you go with and why? I just got off the phone with what seemed to be a very intellegent guy from Atlantic Jet Boats and he said that he would replace mine with a Solas SD-CD-13/21 or SD-CD-14/22. What do you guys think? I don't know for sure if I will need to but it would be nice to know in the future. I just ordered two new wear rings and the impeller remover tool from their site. Because this cavitation proble is getting very annoying! Anyways guys let me know what ya got. :cheers:
