    SHO Running Rough Low Speed

    Have 2012 250 SHO that is running rough when at very low speed (trolling or no wake zones). Runs fine at any other speed or idling. Any suggestions or comments appreciated!

    I don't know a heck of a lot about the sho specifics but for now I'd start with the basics. Check your plugs, fuel filter, and water separator.

    At idle they're smooth just off idle they are a little rough, kind of normal for a SHO.

    Thanks guys...I just changed all the filter, water separator, and plugs so hopefully it’s just normal. Once again I appreciate each of yours advice!
