    General mod/parts question for Kaw-Ultra 250x

    I bought these three products today. I must of had a few dollars burning a hole in my pocket. Anyone have any personal knowledge of how these products can or can not help on the ski? I have other R&D products on ski that seem to work just fine. I do realize I am not gonna getting hp with these parts on. I want to maintain the life and take care of the inside of the ski as long as I can. I am the one who races 1/4 mile drag races with Lucas Oil. Thanks in advance. If I wasted money feel free to let me know. LOL I will still like you all either way Do keep in mind I only pay cost for the parts.

    I have all except the waste gate block off which I wanna get. Keep in mind I did stage one all at once. All goodproducts. I also have a little cavitation like u suffer with as well. Keep me posted if you figure out how to Get completely rid of it lol. A 310 would fix it. From what these guys say we will have a little nice videos by the way

    To get rid of the cav is easy. Just get the prop to liner clearance built up cost about $100 here in aussie land.

    You can make your own block off plates by tracing around a piece of aluminium.

    Yes a 310 would be nice but there is no need to make payments on a watercraft when I own a nice ski to me at the time. I hope those parts are not two hard to install. I will find out in 2 weeks when I do the install.

    Filling up the gap between the prop and liner can be done with a new liner for the pump if its worn out. If the prop is worn out you usually send it off to have them add material (weld) to the outside of the blades then cut/shave them to size. Unless you have a super fancy setback 162mm prop or live down under where prices are through the roof it may be cheaper to just get a new prop

    A new prop doesnt necessary fix it as the liners do wear. Its best to get the prop matched to the liner
