    So I just finished up a SN Superjet for someone. This piece was laying in the hull when I started working on it. Found where it goes on the schematic but still don’t understand where it goes or does. Anyone have a thought on this

    Polaris octane options?

    Was on copart and saw a Polaris octane ski for sale. Head was taken off and it said it wasn’t running. What are some options for this ski? Is there any Yamaha conversions for it. If so, Engine only or pump too? I know anything is possible with some creativity.

    What are these?

    Hey, I was looking on Craigslist and came along an Yamaha VXR 650 in my area. It has an AM exhaust and head that I’ve never seen. Would any one know what it is? I thought maybe a Pro-Tec pipe but I have no idea on the head.

    What engine to build

    Hey there guys. I have a 2008 Superjet with almost everything wrong. Only thing that doesn't need attention is fixing cracks on the hull. Note I said cracks. It still needs a fresh paint job. Past owner left it outside uncovered it's whole life. I got it cheap because it also had a seized engine...
