My water injection elbow failed on my YSM8, ordered up a new elbow, lower elbow that comes out of the engine and the nipple that goes between them. The nipple on the Y 25 is a lot longer than the one that is shown in the parts manual. The parts guy I am dealing with says that is the only one that Yanmar shows. It is a counter threaded nipple, left thread on one end right on the other so I can't just get a longer standard nipple. The nipple in the boat is 8-9" long the stock one about 2.5". Anybody familiar with this problem and have a Yanmar part number for the longer nipple. It is 6 sided in the middle threaded on each end. I have attached a pic of the parts manual, the parts I am talking about are the Injection elbow (7), the too short nipple (16) and the lower elbow (12).
