    Rxt 2018. Carbon Seal / Oil in Air Intake Filter

    So I have a 2018 rxt 2018. The seat is sealed pretty good in this hull. I am finding salt all over my charger. Wondering if this is normal or is the carbon seal leaking a little. Second see pics but when I take my air intake off. I find oil all over the white piece and inside the tube that comes off the supercharger. Bare in mind this is a new charger. Like 2 hours on it. Had it replaced already.

    Your carbon seal is leaking, Causing the salt Residue on the engine. Do you have a CAtch can? Or Is the tops hose routed into the intake tube?

    The replacement is now failing two hours later? Was it rebuilt?

    Either way looks like the seal is defective behind the impeller.

    Nope replaced by dealer. Thought it was the seal last time. I’m wondering what’s behind the charger that can cause this.

    A) The seal is getting too hot, from lack of oil. “Oil sprayer jet clogged?
    B) Improper assembly/defective oil seal in number 2

    I have a Riva stage 2 + IMUK 8550 flash. With low fuel and trimmed all the way up, I get 77 to 78 on the dash with a stock Depitched prop.

    I get 77 on dash with low fuel and trim up with just a scom. Seems like a lot of money to go stage 2 to have it flicker 1 mph faster than a stock ski with a scom.
