Frequently Asked Questions
Q. My New exhaust system is giving off a strange odor in my engine room. Is this normal?
A. Yes. It is common for new insulation, whether it be hard coat or blankets, to “break in” for the first few hours of operation. Some smoking is also common, and will eventually go away.
Q. My silicon hose is discoloring; is it a sign that my new wet exhaust system is running too hot?
A. Not necessarily. Silicon hose will change from blue to a golden caramel color eventually; this is a function of high temperature over time. We do recommend a periodic check of your wet system to ensure temperatures are within limits; most fiberglass is rated to 250 degrees continuous, and silicon hose is rated to 350 degrees F continuous.
Q. Why do I need to support my exhaust system?
A. Exhaust components if left unsupported, can generate excessive loads on a turbocharger, stressing the mechanical seals to the turbo. The exhaust’s welds are also subject to forces beyond their design values, causing the welds to crack prematurely.
Q. My exhaust system has a leak, what should I do?
A. The system should be removed form the vessel, pressure tested, and inspected. A visual inspection with the system in place may not tell the true condition of the system.
Q. What type of exhaust system puts off the least amount of heat?
A. The water cooled system does because the water carries out a great deal of the heat with the exhaust.
Q. What type of exhaust system should I put in my boat?
A. If it is a riser system, we recommend a dry system to help insure that if a failure does occur cooling water has less of a chance of flowing back into the engine. A dry system may not be able to be used at all times due to dimensional restrictions.
