    Need Help With 951 Engine

    I'm putting a piston kit in a 951 engine that I bought taken apart. Where do the orings go that are on the cylinder/head studs?

    Turbo I had the same questions when rebuilding. I called the SeaDoo place they said put the cylinder on and then put the Orings under the head gasket. Push them slightly into the cylinder so they are flush with the top. If I am wrong someone please post, but thats what they told me and thats what I did

    I just pulled a 951 motor apart, and the o-rings where under the cylinder. The engine only had 40 hours on it, so im sure no one had there hands in it yet, even thought the dummies who owned it before me forgot to put the drain plugs in and submerged it, and then tried just firing it up when they pulled it out of the water and busted the crank.
