    personally I would leave it in and just have a spare ready, look and be ready for the symptoms of a failed one. plan to check and or replace at 50hrs if it lasts that long.

    What are the symptoms of a failed one?

    hard starts first and foremost! along with possible reduced performance if it fails while riding and clogs up the exhaust to name a few

    Yep, put it back in and buy a new one for when it does fail.

    The ski will miss on restart, most noticeable if you ride in a 4 knot/no wake zone and then switch it off. If you leave it off for 5 minutes or more and it misses, even the slightest miss, it's probably gone.

    When it fails, it will lodge in the waterbox and restrict some gas flow. This will drop your peak RPM's back. Mine typically go from 7900 to 7600ish. So if you see a consistent RPM drop of a couple of hundred RPM, along with the miss mentioned, the filter is probably gone.

    Cheers, Mal.

    Has anybody else noticed that the Exhaust Downpipe on the older 300X (2011) has the boss in the casting for the Exhaust Filter Retention Screw? Mine appears to have it, and what's the opinion(s) for drilling, tapping, and installing one from the 2013 parts bin on the older models?

    That makes perfect sense to me... So do you know if the 2013 Exhaust Downpipe casting is different, or is the Lamda Sensor mounting boss just drilled & tapped for the "Exhaust Filter Media Retention Screw"?
