[QUOTE="handyandy, post: 441145, member: 18942"] There are a couple threads on here discussing best techniques for sharpening impellers. Shim to 1/32" like obj suggest. I don't suggest sharpening using their technique I prefer to sharpen what would be the top side of the leading edge of the impeller blades as it is sitting in the intake. Sounds like you guys were probably sucking crap up puttering around wearing down the impeller and liner. With a jet you really want to avoid sucking crap up when I'm coming in to beach my boat I trim up then shut it off to just let it drift into shallows so it doesn't suck sand, dirt, mud, and rocks up. With jets you either run over shallows planed out with the motor opened upped to keep the boat planed out to run over them or you drift over them. Puttering over shallow areas with the intake close to the bottom it will suck crap up wearing down your impeller. Figure out how to take the intake and impeller off, and how to sharpen/shim the impeller at the very least if your going to own a jet boat. That is just nature of the beast kind of like owning a car you should at the very least know how to check tires, air them up, check oil, and top off oil. Sharpening and shimming the impeller is just part of jet boat life. [/QUOTE]
