    2011 150 ProXS running rough

    S/N 1B824055

    Running rough at about 1600-3000 rpm.
    Idle seems to be fine as well as WOT.

    Plugs, filters changed this year.

    Any ideas before taking it to the shop?

    Plugs properly gapped and torqued to specifications? They are NOT properly gapped until the INSTALLER does it.

    Did them myself, I will double check them. My torque wrench went missing so not sure on that. I will make sure I check those two items. Thanks!
