I need a new water pump impellar but when I take the serial # to the parts page where they are listed I can't seem to figure out how to transfer that # over to the lookup chart. http://www.iboats.com/Mariner-Impellers/dm/view_id.269210 If someone could explain how or what I'm doing wrong I would really appreciate it so if I need anything else for this engine I might be able to find it.
Mariner 50hp serial #0C188638
