Which is/are required for engine exhaust pipe installations on small passenger vessels?

🔍 Key Concepts

• Exhaust system safety requirements for small passenger vessels in 46 CFR Subchapter T • Protection of passengers and crew from burn hazards and fumes/water • Why backflow of water into an engine exhaust is dangerous for the machinery

💭 Think About

• Think about what could happen if seawater were able to flow backward through an exhaust line into the engine—what kind of damage or failure could that cause? • Consider where people walk, sit, or work onboard: what protections are needed if very hot exhaust piping runs through those areas? • If a dry exhaust exits near the waterline at the stern, what possible risks exist if it is too close to the centerline or too low?

✅ Before You Answer

• Look for requirements that deal with preventing water from entering the engine through the exhaust • Check if there are rules about shielding or guarding hot surfaces where people can come into contact with them • Verify whether placement of a dry exhaust outlet at the transom has any specific requirement about being outboard or away from certain areas

Piping must be arranged so that water backflow cannot reach the engine exhaust ports

Protection where people or equipment can contact the pipe.

Dry exhaust pipe ending at the transom should be located as far outboard as possible

All of the above
