    Running WIde Open?

    I have a 2007 ultra lx. I am wondering for how long can you ride wide open? Should it be done for long periods of time or is it not good for the engine? My thought is that the engine was designed to run at high rpms, but i'm not comfortable doing it for extended times. Am i over cautious?

    So how do you offer this advice when your ski is needing a major motor over haul at 100 hours? You say yours was abused and misused because it was run close to WOT most of the time? Yes I know its a NA vs SC but its the same base power plant........

    Obviously you don't want to be going WOT the entire day. Can the engine handle it? Most likely. Are you causing more engine stress? Most definitely.
    The key to long engine life is oil changes and regular maintenance !

    Major over hall ? My 300 could of used to new vakves and back into service and my 300 is nowhere comparable to his LX and. My ski was raced and ridden offshore for hrs at a time. If you knew what you where talking about you would know the motors are very different rods pistons cams cylinders no sc compression ratio. Hull pump etc etc etc. thanks for your useful input.

    I would suggest, with decent oil, and a full and proper warm-up, (5 liters of COLD and THICK oil) they can be run hard till you run the tank dry. I've run mine hard from day one. These aren't run at really very high RPM.

    As long as the ski is in good operating order, you should be able to run it wide open all the time. They are not like cars or trucks. Proper oil changes are a must. If the ski comes apart it either was not properly maintained, a poor factory design, or the engine has been modified. Now if a ski has 300 hundred hours on it I wouldn't hold it open as long, as things may be starting to wear a bit. The longest I have held my 15f wide open was 24 miles, that is a lap around a lake I go to, by that time my hand was cramped up.
