My Honda BF90A has a broken piece at the point that the washout hose would connect to at the water jacket at the top of the engine. someone plugged the hole with some kind of putty and I would like to replace this piece but not sure what it would be called. Kinda crazy question but there it is does anyone know what this is called so I can look for a replacement ? It bolts to the water jacket with a couple bolts. Thanks in advance for your time.
