    Ultra150 Rebuild! Locked up engine.

    Its not my fault. I moved to FL last June, and had to leave the ski behind. Well in my absence someone thought they could ride it. No one knows who it was. Or no one is saying. Anyway just got it down here three weeks ago. Finally got the old gas flushed out, cleaned the carbs, and a new battery. All of that to hear the "clunk". I didn't try spinning the shaft, I just felt the engine by the starter. I'm pretty sure.

    I'm having some problems getting the heads off. I've tapped around them and can get a little wiggle with my hands, but they won't slide off. Any suggestions would be appreciated.
    Look at how sad this has made my dog. I am VERY PISSED OFF!

    Pull your jet pump and make sure that's not locked. Is there oil in the oil tank?

    Still need to know of something I can spray to loosen up the heads.

    I tried pulling the pump. it won't slide off either. Is there a spray? One of the studs came out instead of the bolt coming off.

    I tried spinning at the coupler. I could feel the prop shaft twitch. but the drive wouldn't budge.
    there is oil in the tank
    I need to get this thing apart. Please help!

    Got the pump pulled back. It spins free as a bird. I tried to remove the pump but it wouldn't slide out. The coupler disengaged witch is were I spun it from. How do I get it the rest of the way off. The manual says just pull back to disengage the shaft. I guess my shafts not disengaging. Any ideas?

    Any tips on pulling the motor? I'm following the manual.

    Yeah, It was a storage garage at an apartment complex I used to work at. Someone had smashed the lock to the lever on the garage door.

    I had to have a puller fabricated for the last salt water 150's that needed the pumps removed.

    the pumps were a total loss, ended up getting a couple of used ones on ebay.

    get some pb blaster and soak soak soak. ( might as well spray some down the jugs too..assuming the rings are rusted)

    The aluminum swells with corrosion and makes stuff a bear to take apart.

    I charge an extra $60 an hour for dealing with a ski that has been used in salt water ( we get them here now and then, folks by skis from salt water markets not knowing any better)

    it can be THAT much trouble

    Hit any bolt you want out with a propane torch ( watch the fuel tank!) then soak with pb blaster..repeat and heat and repeat

    Beat it with a dead blow plastic hammer and give it go..heat and repeat

    I remember that puller going around on the skiworx forum. I got the pump pulled back, I just wasn't sure how hard to pull to get it off the shaft. My ski is only freshwater as of now. I plan on going to surf with it a couple times. But I have to get it running first. Anyway its off now with a few good tugs. Waiting for a friend to help lift the engine.

    Here's pics of the pump. The prop has wear on all the edges, as does the pump. What do I do? I never done this. Should I just send it off to Skiworx?

    personally I had a negative experience with that company.

    Of course that was a few seasons ago and everybody is entitled to a mistake every now and then


    I would research for current gossip on skiwrx before moving ahead.

    Changing bad bearings in an ultra 150 pump is a challenge, due to the pump construction.

    One of the reasons I assume that SBT doesn't remanufacture this particular pump.

    I've managed to get around the design flaw and have rebuilt a few 150 pumps in the last two seasons.

    are the bearings bad?..or just prop wear from grit?

    if the bearings are good, you got bigger fish to fry before worrying about the overall state of the pump
