My new 3YM30 was specced with a Yanmar oil evacuation pump. They were out of stock at the time and today I recieved the pump. It is a monster and I can't imagine that it is the correct part but I can't find a picture of one to show the guys at the shop. Does anyone have one of these or a picture? It is a rotary pump with a crank handle. The one I recieved looks more suited to a bulldozer than a sailboat. Thanks, David
