A Sierra water pump kit, 18-3472, that replaces 5007972 and fits 200-300HP engines from 2009 and up. It is a service kit holding an impeller, key, gasket, seals, wear plate, O-rings, screws and grommets. The water tube O-ring comes four times and the housing screw four times, while the other parts come singly. The name says without housing, so check the contents list against what you need.
Our take
The 18-3472 kit combines an impeller, impeller key, gasket, plate seal and four water tube O-rings for 200-300HP engines from 2009 and up. The name says without housing, yet the parts list includes an impeller housing, so confirm what is in the box.
