Particularly when the inboard marine engine is close to the waterline, it is often necessary to include the so-called “exhaust riser”, a component connected directly to the exhaust manifold. Normally the riser has an external over-wrap where the water that surrounds the exhaust gas pipe circulates, guaranteeing the cooling of the entire circumference of the pipe itself. The exhaust riser of a marine engine aims to guartantee the collection, the mixing and the engine cooling water and fuel gas expulsion.
Exhaust manifolds and risers are therefore essential components for the correct operation of the direct or indirect cooling system of the inboard marine engine.
For all the most common inboard marine engines – Volvo Penta, Yanmar, Iveco Aifo, Mercury Mercuiser just to name a few – SAITO, through its commercial partner SAILOG, sells exhaust manifolds and risers, pipe elbows, bends, dual chamber exhausts and heating exchangers all of them made of stainless steel for deep
