    Ultra 150 seized up

    I bought a 2000 ultra in march and have had it in the water for half an hour it stopped running and is now seized up with water in one of the cylinders it is at a marina and they want to drop a sbt engine in it for 4000$. Seems high to me and I don't want another engine due to it running 76mph before it locked up. Am I sure it has been modified and don't want a new engine. I live in Fort Wayne Indiana and if anybody can help I have money to fix it. There are pics of it on another post.. Really in over my head here

    That sucks! How did it get water in it? Didn't you try to get the water out?

    SBT engines suck, especially for an Ultra! No way do you want to put one of those in your 'Ski!

    If it's had water in it for any length of time, your crank is shot. You can have the crank assembly (includes rods) replaced for much less. You should also replace the rings, and pistons if they have more than about 50-75 hours on them.

    The starter probably needs to be replaced, and you may have water in the stator and the electrical boxes.

    I was dumb and used zip tie on the cap for the hose that goes to the exhaust. I now have it at a independent marina shop waiting on the call hoping no more than 2 grand. Does any body know if the sbt cranks are ok to buy?

    And you weren't able to get the water out before you brought it home... Oh, well.

    I wouldn't put an SBT crank in mine unless there was absolutely nothing else available.

    Not familiar with them. I've heard good & bad about HotRods cranks. OEM is expensive, but you know what you're getting. You really don't want a rod bearing to come apart because it will cut the engine in half!

    Ask then where the bearings come from. You don't want Chinese bearings. Japanese are good.

    from what you describe, your engine is pretty much junked due to water

    +10 on Steve's comments

    how deep is your wallet?

    SBT shortblock w/2 year "warranty" $2k
    I typically charge $600 or so to install an SBT shortblock
    they come in around 3k by the time it's all said and done

    4k is high for this job

    if you want to ride, sbt isn't a bad route to go

    if you want to go you say 76mph..going to be pricey

    unless you love this ski,,get a 4-tec or a ultra 300x

    easy to mod and more reliable in the long run

    I like ultra150 a whole lot. First jetski that really scared the crap out of me.

    sorta like my (really) old Kawasaki 750 triple m/c

    Why would It be junk? I have a 2011 300x and also a 1995 900zxi. I want one from every decade that runs

    after water sits in a two stroke for more then 24 hours, the crank is shot.

    The you have a seizure issue..to do that the right way means redoing just about everything on the motor

    cranks are pricey, boring is pricey, piston sets are pricey and if the seizure is bad, you could need a new jug..pricey

    but if you have your heart set on it for your collection..it will only take a wad of cash to make it right

    Maybe I'm missing something. You have 3 JetSkis, including an Ultra 150 and and Ultra 300, and you didn't know that it's absolutely critical to get the water out of the engine immediately?

    No, your engine is NOT junk. Only the crankshaft is junk. However, since the rods and bearings are a integral part of the crank, they're junk, too. And since you have to pull the cylinders/pistons to service it, the pistons & rings really should be replaced. Do you have to replace them??? No, you don't HAVE to, but you said it used to run 76 MPH (doubtful). If you want it to perform as before, you have to put the engine in the condition it was in before. And don't forget possible damage to the starter, starter drive, and electrical items... Even gaskets are expensive.
