The white box to the right can be typed in just like a search engine. If you are looking for a "manifold" you would type "mercruiser manifold", to find an alternator type "omc alternator" in the box, also you can type in part numbers or brief descriptions. The box is pointed out by the Red Arrow above. There is a button next to the white box that makes the site "Find It" (search).
