    Rave Valve Questions

    Take a look at these RAVEs and let me know what you think. What caused this? They came out of an SBT rebuild. Think they are usable? They will probably need a little filing because one of them doesn't slide freely in its slot.

    Don't file them. Get a can of Gunk Engine Degreaser and soak the RAVES, then clean with a wire brush. It's normal for them to carbon up. The slots should be cleaned too. Wrap a rag around a screwdriver to get those.

    + 1. Soaking them is perhaps the best method, I did the same thing to mine, worked out great.

    Don't be shy to change out the o'rings & gasket.

    I was mainly asking about the wear pattern on the RAVEs. On the one pictured, the slot in the RAVE has been worn down and isn't straight. You might have to look at it close to see. I've already got most of the heavy carbon off. I soaked them in acetone for a few days and then hit them with a wire wheel.

    The wear is normal. I think they are ok, your pics are a bit too blurry to see details to determine one way or the other.

    That looks normal to me. Biggest thing is to clean them up really good and put new gaskets and o-ring and i also unscrew the spring and cut a lil off the female end, that holds the bellow on tighter. Make sure to use a small zip tie on the bottom of the bellow or they will leak and your boat will run like crap.

    The slots were added to prevent frequent gumming of the RAVES, the problem ski it was designed for, was the 97 GSX.
