    07 FX HO Engine into 05 FX HO

    New member here. I have an 05 FX HO with a blown engine. I have a chance to get a wrecked 07 FX HO with a good engine. Will the whole motor swap in? If so, will the 05 ECU be compatiable with the 07 engine?

    I have been told that I would need to swap out both the ECU and wiring harness. While not too difficult of a job, if I don't have to do this I could save some time.

    Thanks for your help.

    The motors are identical. I also have an 07 with a blown engine that belongs to a buddy of mine if you run across another engine please send it my way. Thanks, Julio...

    Thanks for the reply. I know that the ECU carries different part numbers for each year. Will the 05 ECU control the 07 engine correctly?

    Absolutely. Just use your 2005 accessories (Intake manifold, injectors and sensors). Keep us posted, Julio...

    Picked up a wrecked 06 FX HO ski this weekend. I think I'll switch the 05 intake and sensors to the 06 engine. It'll be a couple of weeks (other projects) before I get around to doing the swap, but I'll update this post when I get the engine installed.

    Anybody need any 06 parts? Let me know and I'll get you a price quote.

    Thanks,
    Bill

    I have done some research on HLSM.com looking at their parts lists and exploded views for each year of ski. I tracked down all (I think) all of the sensors on the engines and the only different part number I that differed were the ECU's. I think that I can swap the engine and ECU from the 06 into the 05 and be good to go.

    Do these machines utilize a crank position sensor? I couldn't find one listed for either motor.

    Thanks for your time.

    The crank pos sensor is built into the magneto on front of the engine cover. Let me know if you come across another motor, I need one for one of my skis, Julio...

    Your engine should drop right in. The ECU has a slightly differant # the update code at the end of the #. What parts do you have? Might be interested in the whole ski less the engine. How did it get trashed?

    Also that engine uses a cam position sensor not a crank sensor. Look in schematic electrical #2
    Thanks Roy
