These Groco strainers have a unique access door which makes it easy to clear debris and marine growth that can hamper performance and even cause premature failure in water pumps and exhaust systems. Eliminating the need to haul boats out of the water, these strainers can save enormous amounts of time and money in the event of an accident or emergency which requires immediate servicing of the strainer itself. Available in various sizes to suit a wide variety of vessels.
