ok the first question is when my fuel tank was full with 2 guys i couldnt get the boat to plane out, im hoping the reason why is the pics, the wear ring was totally scored and the impellar had a nasty bend in the leading edge, good thing i found out when i pulled it was its a skat trak 14.5-22.5 exactly what i have so i can send this one in and get it refurbished, also when i looked at the parts diagram for the ride shoe it shows a neopream seal that my local dealer has for 7.00 but he has one listed that goes in front of that for 45.00 when i pulled mine apart all that was on there was the neopream one, am i missing the spendy one? also in the pics you can see the vanes on the diffuser one has a large chip missing and the other 2 are scratched up a little, got my new carbon seal and boot and stainless cup with o rings in today, also a huge chunk of my gelcoat gor ripped off and i found some slow curing epoxy first coat in the pics, waiting for it to cure so i can put another coat on, thanks again for the advise and sorry for the long post
