    Seadoo 947r question

    Good day guys,


    I have a 947R engine with new pistons in it.
    Here is my issue in the below mentioned picture you can see the sleeve is cracked all the way on. Though you cannot feel it by hand I can see it.
    Will there be any problem running like this or should I replace the sleeve?
    All opinions are welcome.

    Yes, you must replace it. That's going to catch a ring and destroy itself.

    Did you just have that bored and new pistons installed? The pistons look new, but I don't see any cross hatching on the cylinders indicating it was bored to match new pistons.

    Running it like that will last probably 10 - 15 minutes then another rebuild at a minimum.

    There is also about zero port chamfering around those ports.

    After you replace the cylinder, will the engine seize again?

    Did you find out what caused it to fail?
