Stainless Steel Marine Manifolds & Risers


All stainless steel manifolds have an anode built in to prevent electrolysis. We recommend replacing these every 6 months


Stainless steel manifolds weigh 7kg*each compared to cast iron that can weigh up to 50kg each


With the weight reduction, one piece construction and patent design, these manifolds are a performance part for your inboard


When you reduce weight in a boat this increase fuel efficiency. Stainless Steel Manifolds can reduce weight by 150 kg


This eliminates gasket failure that leads to rusting of the manifold, riser and worst case engine failure from salt water getting into the engine.
