A particularly important part of annual maintenance is inspecting your boat thru hull fittings. Improperly maintained marine thru hull fittings are a number one cause of sinking – so inspect them annually for any deterioration. Additionally, keep hoses from clogging by adding a scoop strainer on deck and marine intake strainers inline before water pumps. Fisheries Supply is your premier supplier of boat intake and thru hull strainers from the top brands – so shop now and save or browse our wide selection of seacock valves.
