Tier 4 lets you do something you may not do often: enjoy the view.

If mariners know anything, it’s this: Success isn’t always easy. But thanks to our EPA Tier 4 / IMO III solutions, the QSK38 and QSK60, complying with emissions standards is. With the latest aftertreatment added to the already-proven QSK60, midlife overhauls become a thing of the past. There’s no need to change out major components until a full overhaul. And best of all, you can keep up with emissions regulations without sacrificing uptime, or one ounce of power.
