Roger66:

I'm like you......need to have "jet".....while I still bank fish, in the summer, the vast majority of my fishing, September 16 to March, is in jet boat water.

New liner, filed impeller, grease everything, make sure on the .015 spacing. That cost would be less than $100.00

Cost goes up, if new Stainless Impeller, or if shaft in bent, or if a shop does the work. You might want to call the good folks at Wooldridge, they have a vast amount of knowledge on jets/ and impellers.

Good luck !!!!!!!
