    Going to purchase a FX HO and need help

    Hi Guys and Dolls,

    I'm new to the forum. I am looking to purchase a used FX HO. I found one that I am going to look at tonight, and could use some advice as to what to look for.

    It is an 06 FX HO with 39 hours on it.
    The unit is out of the water, but the owner has waterfront location and will put it in to test. I have experience riding, but what should I look for....

    Ie: checking the Oil.. should I check it cold or when hot.. and where can I find the dipstick ? How long should I test drive, and what to look for ...

    Any help would be greatly appreciated.

    Lee

    Check oil per manual, he should have it. Test ride for minimum of 15 minutes, preferrably longer. Dipstick will smack you in the face once you open the seat.

    • Compression test, correctly done.
    • Pump inspection
    • Prop inspection
    • Hull inspection for damage
    • Salt corrosion or sodium deposits
    • Throttle and shift cable ease
    • Intake grate inspection
    • Smoothness of engine acceleration throughout ROM range.
    • Feel for cavitation on launch

    CCW,
    Thanks for the reply. I do not have the ability to do a compression test.. can you in laymans terms tell me what to look for at the pump and prop?

    With that ski, set the display to show rpms on the needle gauge. Set the speed to show digitally in mph (the manual will tell you how to adjust the settings). Find some smooth water and open it up. At WOT you should see the needle at 10,000 rpms. Your speed should be right at 58 mph (via GPS). You can download an app for a smart phone that will give you an accurate reading. The speed-o-meter on the ski is not reliable and will probably read 62-64 mph. If you get these results you have a good engine and a good pump. No need to do a compression test.

    I would look for corrosion, but if you get the above results and the ski looks good otherwise, you are good to go on this model. These older FX HOs are pretty bullet proof if taken care of. Take a flashlight to look at the pump and prop. You don't want to see big nicks or dents. You also don't want to see major scratches in the housing. There should be 0.5 mm or less clearance between the edges of the prop and the housing.

    Check the oil only when the engine is HOT on the pre 2009 FX HOs. Best time to check it is after you have ridden for at least 10 minutes. Get off in shallow water and do the check. As said above you cannot miss the dipstick once you remove the seat.

    very simple , wot 10,500 rpms , they idle real smooth and calm , pump and prop look for corrosion it's very normal to see dings on prop , most of the time it will need to be replace anyways , the prop is like a car tire it gets all the road bumps .

    I would not purchase a ski without doing a compression test!!!! You can purchase one down the road from your place at Harbor Freight. Best $30.00 you can spend.

    Thanks for the responses and the good advice. I will test drive and downloaded a GPS app for my Android.
    Can you tell me how much of a variable in speed/rpms is acceptable before determining that there is a problem with the ski that is not worth purchasing ?

    To the OP, when you have this many guys telling you to do a compression check, I would invest the 30 bucks and buy one and learn how to use it. Last thing you want is to buy a ski and find out later, you're replacing rings and/or a piston.

    And remember, you're not so much at exact numbers as you are for consistency among the numbers. (obviously you don't want 120,121 and 125 either...LOL.
