Hoses for Boat Exhaust Systems

Having the right hoses connecting your marine exhaust system is as important as the right manifolds and mufflers. Heavy-duty marine exhaust hose will direct gases and water where they need to go, keeping the engine cool and your passengers safe. Shop for exhaust hose replacements at Marine Parts Source whenever you need to swap cracked, broken or worn-out hoses. We carry inboard boat exhaust hoses from leading brands like Sierra and Vetus that manufacture high-performance parts for professionals and serious enthusiasts.

Marine exhaust hoses are available in numerous sizes to fit any system, and you can order them with soft walls or wire-reinforced hard walls. We also have corrugated boat exhaust hoses for making tight bends or for use in high-pressure systems. Order wet exhaust tubing in large bulk rolls, short runs or custom-cut by the foot.
