    Fogging FZS

    Im helping a friend of mine with his FZS. We did the intake manifold ribbon delete today. What a pain that was. Actually found it easier to remove the wiring harness from the intake manifold, and pull the whole manifold/throttle body out to remove the ribbon. Got that done and now he is wondering about fogging the motor. What is the best way to do it, and is it even necessary to do?

    I tried the search and found nothing that was really relevant.

    I think fogging thru the plugs is a good idea unless you have an air/fuel gauge/O2 sensor. Fogging oil probably isn't good for them.

    Well, I always have on watercraft, and I do not think it can hurt. Don't do it on my cars I store in the winter though, and haven't had any trouble there.

    I just located the factory manual and it says to do it through the breather hose. Looks simple enough to do.

    Fogging is necessary when the ski won't be running for a long period of time... especially if you ride in salt a lot. The fogging oil helps lubricate internal parts and coats them to prevent corrosion, specifically on the exhaust valves.

    It is very easy to do: hook the ski up on the hose, pull the hose that comes out of the oil breather (the hose that goes into the air intake), and then spray fogging oil down the hose for 3 seconds. The ski should choke out.

    No salt within 1000 miles of me. We will do it through the breather hose.

    It's still a good habit to get into, especially when you store the ski in the winter. But besides that, you should be fine.

    Mike,

    On another note, I noticed the list of mods you have on your ski. My friend has the power filter, free flow exhaust, intake manifold upgrade, PPK and R&D grate. Se are trying to figure out what prop to use. Right now out of the hole, its all over the limiter. We will see what it does up top now that we did the intake manifold upgrade. I have a feeling that it will need more prop. Any good suggestions? We ride Lake Michigan, so its usually rougher waters. I would think a Skat of some sort, I just have no idea on what pitch to run.

    I've had excellent results with my skat 13/20 with the mods in my sig. The prop spins maybe once out of the hole and then it's all acceleration from there. The skat in my expirence is also faster than the stock prop at lower rpms, so top speed will improve as well. I gained 1.3 mph alone by switching from the stock prop to the skat and I lost all the cavitation I had with the stock prop.

    There's plenty of guys on here that use a repitched stock prop with good results but I've never tried it myself.
