Perko 858E 493/500 Water Strainer is a specific replacement part for Marine Sea Ray 270 boats and other models. This is missing the top cover, stainless filter screen, and one of the cover studs.
This is new, believe it or not, and has never been installed in an application, but it was not stored properly over the last few years and was used for Parts. That is the reason for the missing screen, top and stud. Something that says used. You will receive the exact one pictured in its current condition.
