    2008 RXTX Only Reaching 6250 RPMs

    I have a 2008 RXTX that hasn't run right since it was started this year. It ran beautiful last year and I winterized it as I have done for the ten years I've owned it. I did some research on here and led me to clean the map sensor. No such luck. This is what I've done so far:
    Check compression =135 @ all cylinders
    Clean map sensor
    Siphon last years stabilized fuel and replace with 93
    Swap a known good coil pack into the mix
    Remove all fuel injectors and clean with 12v and carb cleaner
    New battery
    Hate to bring it to a dealer when I am sure I dont need to.

    In 10 years this ski has been 100% reliable and I am at a loss. Thanks for any ideas

    I noticed lots of members looked at this post but never responded. Just want to let you know what was wrong with the ski. After lots of troubleshooting, it was a bad fuel injector. I cleaned them, but a local marine repair shop has the ability to flow test them and one tested bad. I always hate when I follow a thread and never find out the final fix. Well, there you have it. Ski is fixed and sold.

    You didnt post in the 4 stroke sub-section. Thats probably why no on responded, everyone in this section talks about 2 strokes.
