My lower unit intake screens are almost completely gone. I know the screens are vital to keeping dirt, grass, and debris from getting to the water pump area. Can any of you knowledgable pros help me out with l/u removal, screen part # or equivalent, and impellar replacement procedure since I'll be in that area?<br />Heading to Black Lake in a few months and it's a high grass hatchery so the lower screens need adressing. Any help would be greatly appreciated!
