    Pull the engine.

    To pressure test the crankcase, you have to build a fixture with a low pressure gauge some hoses and fittings. I use a needle valve on mine and I run my compressor, then turn it...

    I don't know what the conversion factor from US dollars to OZ dollars is, but $5K is awfully high. Many shops here won't even work on 2-strokes anymore, so you have to do your own.

    I say do it...

    I can guarantee that there is trash in the bottom. At the very least, turn it upside down and flush it out very thoroughly with a pneumatic solvent sprayer.

    If it hasn't been apart in a while,...

    Looks like you're S.O.L. now, son. I'm the only one that's even tried to help you, but no more. For the record, the Ultra 150 has circuit breakers, not fuses. The main one will pop when you do...

    Are you getting any water in the hull? Sounds like it could be an exhaust leak.

    Wow! I didn't realize that there were so many rocket launches.

    I don't see any major scoring of the cylinder, just aluminum buildup. It can probably be cleaned up with judicious use of muriatic acid and honing.

    Sorry that nobody has replied to you yet, Igor!

    I'm not familiar with the 800 engine. I would suspect that the piece you see with the 'garden hose' is actually an aftermarket flush adaptor. Does...

    That's interesting. Could be the problem.

    Did you check the oil level with the engine being level and after it has been run a couple of minutes? It will read low when cold and if you put too...

    Whoeveruwant, this is getting ridiculous. You have THREE threads going about the same problem.

    If the wire is melted, then replace it.

    There isn't a circuit breaker between the battery and the starter relay. There should be a breaker between the battery and the circuit that operates the starter relay. That said, if it's clicking,...

    What often happens with starters is that the brushes wear out or burn and don't make good contact, or the magnets inside the housing come loose and jam the armature so it can't turn.

    The balcony of our 10th floor condo ws 4 miles from SpaceX. Yep, would love to catch it from there with a telephoto lens.

    I'm trying to help. Did you check the main circuit breaker? If that were popped, I don't think it would click, but it's worth checking.

    I believe that it's possible to hook up the starter relay...

    Any idea when the next launch is scheduled for?

  18. Something Most People Will Never See From A JetSki

    We recently returned from our annual trip to South Padre Island. While there my wife and I, plus another couple, took a little spin out in the Gulf of Mexico.

    Welcome aboard, michalez!

    It's perfectly normal. Think of the impeller as a bell on the end of the driveshaft. Every time the engine fires, there is a pulsation in the driveshaft, which is like...

    Welcome aboard, DLStryker!

    There have been a lot of problems with the ECM on the DI models. Before condemning it, I'd suggest that you disconnect all wiring harness connectors and inspect them...

    This is also a problem on Yamaha 2-stroke boats. When towing someone, I set one engine below the transition point, and the other above it. I use the higher speed engine to control the boat speed. ...

    I do not see it in the Ultra 310 Owner's Manual, nor the Service Manual.

    However, it does appear in the Ultra LX Service Manual, and as an addendum to the STX-15F Owner's Manual.

    Not sure about the PV engine, but jumping from 4K to 5K is pretty normal operation for these engines. It's due to the tuned exhaust system and that's where it kicks in and gives it a little boost.

    I didn't mention a relay. I was speaking of a circuit breaker that you may have popped when you hooked the cables up backwards.
