This kit contains the internal wear components of the water pump assembly, allowing you to rebuild the pump using your existing housing rather than replacing the entire unit. Each part in the kit is constructed with precision and is designed to meet or exceed the quality of the original equipment part it replaces.\u003c\/p\u003e\u003cp\u003eThe 18-3390 is intended for outboards where the water pump housing is still serviceable and only the internal components -- such as the impeller, plate, and cup -- need renewal. Sierra also offers a version of this kit with housing included (part number 18-3392) and a standalone housing kit (18-3391) for boaters whose housing is worn or damaged, so the correct part can be selected based on the condition of the existing pump housing.\u003c\/p\u003e\u003cp\u003eThis kit fits a range of Evinrude\/Johnson outboard motors spanning 140 HP, 150 HP, and 175 HP, across multiple production years and shaft-length configurations, including SL, EL, and DI variants.
