Compact Genset Muffler Fits Tight Spaces

Fitting a generator and its exhaust system into a new build or a retrofit can be challenging, especially in a confined engine room. Marine Exhaust Systems said it aims to solve the space problem with its new whisper-quiet Series 4 Thinline Wall Pack Generator Muffler. Currently designed for up to 35 kilowatt gensets, the muffler is 12 inches wide, 17 inches tall and four inches deep. Its compact, low-profile size makes it suitable for any marine application, and it can be mounted on the hull side, a bulkhead or within the recess of a generator body.

MES, Viking Yachts Partner for Quiet Performance

Viking Yachts worked with Marine Exhaust Systems to introduce a convertible sportfishing yacht with a resin-infused hull, the new Viking 92, which employs Marine Exhaust Systems’ TL Linear Series mufflers to keep the roar of the twin 2,635 hp Tier 3 engines at bay. A muffler in a tube, the design of Marine Exhaust Systems’ patented Linear Series muffler technology are adaptable to the size and horsepower of today’s modern sportfishing boats, and require less space, creating room for larger fuel tanks or equipment.

Custom Exhaust System Quiets Lively Sportfisher

American Custom Yachts president Dominick LaCombe knows every component is important when it comes to making fine and fast vessels. His new 90' custom sportfisher C'est La Vie pushes the power package envelope, with nearly 9,300 hp at his command to fly across the waves at almost 48 knots. The beefy twin MTU diesels require precision-engineered exhaust systems to handle high temperatures in scant available engine room space. To optimize performance and help tame noise aboard C'est La Vie, LaCombe turned to Marine Exhaust Systems.

New Compact Genset Muffler

Equipment noise can quickly spoil the ambiance of even the most luxurious craft. Such problems are a thing of the past for lovely 130' Lady Kath, according to her captain, Bill Hipple. A new Marine Exhaust Systems G-19 water drop generator muffler significantly reduced genset exhaust noise, creating more peaceful days and nights for all onboard. After the installation, Lady Kath's 65 kW naturally aspirated Northern Lights generator exhaust was only 74 dBA. This allows normal tone conversation.

The Weakest Link

The world is changing fast and this is especially true in the fast boat sector. Since the millennium, rigid hull inflatable boats (RHIBs) and high speed craft (HSC) have been at the cutting edge of maritime operations for everything from homeland security and law enforcement to extreme weather rescue. For over 30 years specialist organizations around the world including the RNLI (UK lifeboat), Royal Marines, US Navy and US Coast Guard have driven the evolution of fast craft. They know what has worked in the past and know what boats they want for the future.
