Sierra Manifolds & Risers – The Perfect Replacement for your Engine!

February 21st, 2018 by SeaStar | No Comments » |

For those not so familiar with engine parts, manifolds & risers are part of the exhaust system and are essential to the smooth running of your engine. Most are made of cast iron as it withstands extreme temperatures (hot gases & cold cooling water) but is also prone to corrosion in the harsh marine environment. This corrosion is one of the reasons that manifolds and risers will need to be replaced at some point, it is just a matter of when, depending if you are in fresh or salt water environments. Failure of a manifold or riser can result in catastrophic engine failure if there is water intrusion into the cylinders.

Sierra Manifolds

If you run your boat in fresh water the manifolds will likely last for many years without having any problems. For boats used in a salt water environment the manifolds & risers should be checked regularly as part of your maintenance program. How often will depend on where you keep your boat – boats in warm sea water in southern States will likey need replacement more often than those in cooler seas further north.

Utilizing a state of the art manufacturing facility for all the manifold products, they are manufactured as a direct OE replacement and are fully interchangeable with the OEM products they are designed to replace. Computerized CNC machining ensures proper gasket mating surfaces, and uniform wall and water jacket thickness. All are 100% leak tested before shipping.
