    Re: ARX1200T3 misfire

    Yeah, check compression
  2. Re: 2002 Honda Aquatrax F12X turbo died with no warnings

    Most likely it is a reason why it was dying, engine needs fresh air to run properly and you were making it run on burned air, because exhaust gases were getting inside the hull. It will never run...

    Re: Pictures of water in oil?

    In this case (picture with 4 bottles) there's a lot of water in oil, so probably easy enough by just looking at the dipstick.

  5. Re: Picked up a 2003 F-12X project; need some help please

    To answer your question from other posting... most likely you cracked front cover if the ski wasn't winterized on time.
  6. Re: Picked up a 2003 F-12X project; need some help please

    What might have happened is previous owner winterized the ski but little too late, so it got hit with frost BEFORE it got winterized.

    You wouldn't see the damage until you take it on the lake,...

    You can't really tell if there's water in oil by looking at the dipstick, the only way to tell is when you drain bit and put in clear plastic bottle then u can compare (don't compare it with new oil...

    Re: Yamaha Waverunner FX 140 won't start

    Remove spark plugs and rotate engine by hand and see if there's any resistance, if there is then you got something going on with your impeller.

    Check compression while you're removing spark plugs....

  13. Re: 2002 Honda Aquatrax F12X turbo died with no warnings

    Next step would be to check if you have spark, let us know if u have spark

    And then you check fuel pressure, or at least do a little of starting fluid and see if it fires up, if it does then your...
  14. Re: 2002 Honda Aquatrax F12X turbo died with no warnings

    Good Compression is 171 psi... 125psi is kind of on the low end, but I think it should still start and run ok.

    I wonder if your compression gauge is accurate.

    125psi is only 73% of 171psi,...
  15. Re: 2002 Honda Aquatrax F12X turbo died with no warnings

    It's either fuel injector or computer issue.

    Re: VX 110 Problem MAX 7200 RPM not easy to solve

    Can you rev it over 7200 when not under load (when not in lake). If it goes over 7200 without load then it's definitely something with compression or anything of that nature.

    Re: Pictures of water in oil?

    You definitely got some water in oil. Get a small bottle after drinking water, and let it sit for few days and u will see separation.

    Re: VX 110 Problem MAX 7200 RPM not easy to solve

    I would say oil level or impeller has nothing to do with your 7200rpm.

    Do you have a good compression across all cylinders?
    When was the last time you checked your valve clearance?
    Was engine...

    Ok, exhaust manifold has 4 water outlets, right?

    To TEST with WATER (you have to remove it)
    You plug 3 of water outlets and send water into the 4th one and see if water leaks anywhere, right? .
