    catch can

    Is there really a need for a catch can. Before anyone says anything I understand the purpose and how a catch can works. I was just wondering how oil really gets discharged out and is caugh in the can. I'd llike to hear from anyone who has one and how often they empty it. The only reason im asking because on most automotive application most of the old timers that come in to my work use just a breather filter. If little to no oil is discharging then i might just find a location for a breather filter and run a section of hose to it.

    Usually under normal circumstances, you get about an ounce of fluid after a days riding. I think a breather alone will make a mess inside your hull. Mine tends to "breathe" some mist around the can and make a mess, so I would think no can at all will be messy. Or it will just run back into the hose and engine and dilute the oil, causing the oil level to rise, and the engine oil will get contaminated.

    wouldnt a constant mist of oil actually be a good thing for a saltwater ski?
    i mean, if it got too oily/dirty a 5 gal bucket of hot soapy water would wash all the oily grime off, and engine would look like new?
    i spray several cans of bomb lube on my engine every season, this would be like "auto" lube...

    Well if you dont mind having oil spill everywhere inside your hull after riding then you can use a breather filter... ...I have over 80 hours on my ski and have never filled by catch can, better yet is not even halfway...

    In salt water I would just leave it going into the intake. The oil will keep the throttle body from rusting up.

    i agree definitely keeping the vent into the intake, was just curious about slapping a filter on it and venting to the engine compartment...

    Wow, my T-X has about 1/4 full catch can with 10 hours of use without emptying can. My rxp does not seem to catch the same amount. less.
    So what gives?
    What makes one of my skis catch more per tank of gas per ski?

    Good for salt water riders. But remember it will coat the inside of the IC reducing its efficency
