    R&D intake install

    You guys putting the flex ducting back in or leaving it out? I was thinking about cutting them to about 10" (just below the filter) or leaving them out?

    That's what I'm doing I think. They don't appear to even be functional so not sure why Yamaha even wasted the time and money on them??

    I re-routed mine. I have one so it lets out just below the intake (in case water gets in it) to supply cool air directly to it. The other one is just in front of the SC.

    It appears to me the ends are sealed?? So I'm not sure how water would get into them? I didn't tear it apart but no obvious opening to me.

    If water comes over the top down by the steering column, it gets in them. Up in there is where they bring in the air through a duct.

    Ok cool. Might cut them down and put them back on.

    The flex tubing is put there to channel water to the bottom of the hull should water get into the air intakes on the side cowlings. I left mine in because I do a lot of ocean riding and I like the extra safety.

    I believe they are also to prevent water intrusion if the boat was flipped unside down in the water. If you think about it, the opening of the duct would be above the water line when the hull is upside down.
