The Marelon Integrated System valves were specifically designed for production boat builders. Forespar's complete system comes with a flush or mushroom head "buttress" threaded thru-hull for exceptional strength. When the complete system is used Forespar supplys an emergency thru-hull plug as a cap in the handle. This plug can be used if needed by plugging the thru-hull from the outside to allow full disassembly of the valve to clear a clog or replace the entire body all without having to haul the boat. All configurations meet or exceed ABYC standards, are U.L. Approved and ISO Certified.
