    2013 300x down to stock rmp range with riva racing stage 1 kit

    Last week my ski was running in the 72-73.7 (7800-7950 rpm) range all weekend long with the occasional bogging down when applying full throttle at a stand still but would then immediately come back to full power. This weekend my ski was only doing stock speeds at about 7400-7650 rpm. There was not a F1 error code so i'm assuming the SCOM is still installed correctly. It did however cutpower like it did last weekend a few times. Any ideas would be great. Thanks a lot. Also, I didn't notice any water in the hull after pulling it out of the river.

    weather changes can have a big impact on rpm.....

    Exact same weather conditions, definitely something mechanical. Maybe a boost leak?

    You haven't checked for those yet! ? Haha I thought we were searching for maybe not so obvious things. How about dirty intercooler?

    Hey hey, now were on to something! Thank you! I will be checking that out for sure. I should of put this into the original post but last weekend due to being insanely hung over, I towed the jetski with my boat instead of riding it back. I was towing it probably faster than I should of been. I think I was towing it at about 20-25 mph. Could that have caused damage to the ski?

    Hard to say. Around here though we like to check obvious things first. In no particular order on the 300's when things aren't running right..... oil level, intercooler cleanliness, exhaust filter, boost leaks, plugs then go from those usual suspects

    +1 on the pesky Exhaust filter. I noticed my ski, for the first time ever today, was hard to start. Guess an inspection is in my future as well..

    The ski was serviced at 29 hours when I bought it. It only has 36 at the moment. I will take a look at all the obvious things after work today. I never really checked the boost gauge but it is a few notches down from 15 psi. I want to say atleast 2-3. It does always fire right up though without hesitation when hot or cold. I did some liquid in the hall that could be oil but the engine oil is fine.
