Metcalf Marine Exhaust
Soot Control Solutions · For Yachts
Cleaner water. Cleaner air. Cleaner vessel.
MMX designs customized marine Diesel Particulate Filter applications that cut soot production dramatically — engineered to your generators, your space and your vessel. We've been designing and installing emission control on high-profile yachts for years.
Why It Matters
Soot damages everything it touches.
Soot, fumes and slicks aren't just unpleasant — they degrade the vessel, the water around it, and increasingly, your welcome at the dock. A DPF ends it.
The vessel stays clean
Paint jobs last longer and the hull stays clean without constant washing. No black film creeping across the transom and deck.
Reclaim the aft deck
Run the generator and still enjoy the aft deck, regardless of wind direction — no exhaust odor, and your neighbors at the dock notice too.
No slick on the water
Swimmers won't see an oil slick of unburned fuel on the surface, or catch a whiff of it. Cleaner water everywhere you anchor.
The Technology
Two paths to a clean burn.
Modern DPF technology has drastically lowered the exhaust temperatures needed for regeneration. Our experts determine which system fits each generator on your vessel.
Uses only existing exhaust heat
For engines that create sufficient heat, we can now offer units completely without the heating elements used in older technology — regeneration happens on the exhaust heat the engine already produces.
The cleanest, simplest install where the powerplant supports it.
Engineered assist for cooler engines
Some generators are better served by an active regeneration system. Our experts help you determine which system is best and explain the differences and advantages of each technology.
Every unit is custom engineered and designed for your specific vessel.
Get Ahead
Stricter laws are around the corner.
Most of the world is on the brink of stricter emissions regulations for all vessel types. Though aimed mostly at commercial vessels, these laws immediately affect the yachting industry — and in many areas, they already have.
Be ahead of the curve. Once the laws take effect, prices for these systems are likely to rise and qualified installers will be in short supply. A free evaluation now tells you exactly where you stand.
Some marinas are already refusing yachts with high soot emissions
Noise reduced by 10–12 dB alongside the soot reduction
Much lower maintenance compared to older units
Customized design to maximize use of limited engine-room space
