witch jet unit confused

[Magnum Man]

My 1981 wooldridge has a turbodrive 753 model 3 stage. It looks just like the kodiak and hamilton units. it has 7.5" impellers.
Im told they are are all the same. im kinda confused on this. I need to repair or replace my impellers and sleeves/wear rings. where can i get these parts?

Your'e correct on the jet drives being the same. As far as parts about any boat repair shop around Fairbanks has them. You might try advertising on this web site's swap and sell room. A lot of people have gone to the 10 inch single stage pumps and they have used impellars for sale. Go with stainless if you can buy them right as they last a lot better than the bronze ones.
