Vetus Exhaust Systems for High Performance Craft Specially developed for fast craft with powerful engines, where very often there is no space available for installation of a waterlock and/or gooseneck. |  |

• Application in combination with water-injected exhaust systems only.
• All parts are made of synthetic materials (no corrosion).
• Tremendous reduction of exhaust noise.
• Back pressure is absolutely minimal.
• Compact dimensions and light-weight.
• Stainless steel mounting brackets for the muffler are standard supply.
• The transom connection can be stainless steel (model TRCS), or reinforced black plastic, with a stainless steel band (model TC). Both types are provided with a check valve.
• With the muffler model MV a temperature sensor for the raw water alarm is optional and can be supplied with the muffler.
The muffler and the transom connection of this exhaust system may only be installed when the transom connection is positioned at least 5 cm lower than the outlet of the engine’s exhaust manifold, in which case the flow of the seawater, injected into the exhaust bend, will always be directed away from engine.
Both the muffler and the transom connection are provided with a check valve (”flapper”), which ensures that under no circumstances (e.g. when in waves or manoeuvring astern) can the seawater flow towards the engine. Therefore, this system makes the installation of a gooseneck unnecessary. |

![Vetus Plastic Mulffler Type MV [with check valve]](mv_150.jpg) | Vetus Plastic Mulffler Type MV [with check valve] Each MV muffler features a connection for a temperature sensor, which triggers an audible alarm if the temperature of the exhaust gases/cooling water mixture exceeds an acceptable level. This ensures the best protection for the engine, as it provides an immediate warning when the raw water flow is impeded, long before the coolant in the engine itself becomes overheated. VETUS marine engines, though, do not require such (additional) security device, as they all feature an exhaust temperature alarm as standard equipment. |

 | Vetus Plastic Muffler Type MF The muffler model MF may also be used for fast boats with powerful engines and is more suitable when the exhaust hose has to run low down in the boat. In this case the transom outlet does not need to be lower than the outlet of the engine exhaust manifold. The muffler will also function as a waterlock when the engine is stopped.
- For hose diameters 90 mm and 102 mm : volume 13 litres
- For hose diameters 127 mm and 152 mm : volume 43.5 litres |

 | Vetus Water Mixer / Swirler In some boats the (VETUS) exhaust muffler must be positioned so closely behind the engine’s exhaust manifold (this is especially true in the case of near horizontal exhaust assemblies), that the injected cooling water does not always mix properly with the hot exhaust gases. This often results in the exhaust hose and/or the muffler becoming overheated.
Installation of a VETUS water mixer directly behind the exhaust manifold will overcome this problem. The water mixer is available for exhaust hoses with inside diameter of 90, 100, 125 or 150 mm. |
