    where can i find seadoo 92mm pistons?

    ive got a spare 951 with a blown topend, going to beef up the crank and bore it to the max. i been looking all over the net but can only find the wiseco 91mm pistons. anyone know where i can buy the 92mm pistons and the sleeves to go with it? also if i just stick with the 1020cc(91mm) will the existing sleeves be thick enough? thanks

    go with the 91mm pistons. they are cheaper than the 92mm's and the stock sleeves will do fine. otherwise you have to resleeve for the 92's and will have to again everytime it blows up. with 91's you could go up to the 92's if it ever blew up.

    The above statement is NOT correct--92's work fine in the stock sleeves. Rotax makes 3 sizes of 92's-- 91.89, 91.99, 92.09 and Miller has 2 sizes beyond I believe, but his have a domed piston crown, not semi flat like the Rotax racing...
