Question 1

What services does D'Angelo Marine Exhaust offer?

Accepted Answer

We design, fabricate, install, repair, and service complete marine exhaust systems for main engines and generators — including custom 316L stainless and Inconel piping, mufflers, water-lifts, risers, bellows, wet elbows, lagging, and our patented SeaClean diesel particulate filter (DPF). We also stock and ship exhaust parts worldwide, perform on-board surveys, and provide full engineering drawings for class submission.

Question 2

Where are you located and what areas do you serve?

Accepted Answer

Our 30,000 sq ft engineering and manufacturing facility is in Fort Lauderdale, Florida, serving Miami, Miami Beach, Fort Lauderdale, Palm Beach, Boca Raton, Stuart, and the entire South Florida Tri-County area. Our mobile service teams also travel anywhere in the world — from the Caribbean and Mediterranean to the Pacific Rim — to install, retrofit, repair, and commission systems on-site.

Question 3

How long has D'Angelo Marine been in business?

Accepted Answer

We have built custom marine exhaust systems since 1986 — nearly four decades of continuous operation under the same family ownership. In that time we have completed thousands of yacht, sportfish, mega-yacht, commercial, and military exhaust projects worldwide.

Question 4

What makes D'Angelo Marine Exhaust different from other shops?

Accepted Answer

Three things: (1) every elbow is die-formed in tube size for a perfect, flow-efficient fit instead of being welded from mitered segments; (2) every welder on our floor is AWS-certified and we keep a 1,625-gallon Argon tank on site for atmosphere-protected TIG welds on 316L and Inconel; and (3) we are the only shop in the industry with the patented SeaClean DPF system and variable pre-heater technology.

Question 5

Who do you typically work with?

Accepted Answer

Captains, engineers, owners, project managers, shipyards, and naval architects — on private yachts, sportfish, mega-yachts, commercial vessels, and military platforms. We work directly with builders like Feadship, Westport, Viking, Bertram, Benetti, Heesen, Burger, and Lazzara, and with engine OEMs including MTU, Caterpillar, Cummins, Detroit Diesel, Deutz, M.A.N., Scania, and Baudouin.

Question 6

What is a marine exhaust system and why does it matter?

Accepted Answer

A marine exhaust system carries hot exhaust gases and (in wet systems) cooling water from your engines and generators safely overboard. A well-designed system keeps back-pressure low so the engine makes rated power, controls noise and vibration in the engine room and aft deck, prevents soot staining on the hull, and protects nearby components from heat. A poorly designed one costs fuel, shortens engine life, and creates onboard discomfort.

Question 7

What is the SeaClean diesel particulate filter?

Accepted Answer

SeaClean is our patented DPF system that captures up to 98% of soot particles from marine generator exhaust. Unlike automotive DPFs, SeaClean uses a variable pre-heater controlled cycle-by-cycle to maintain continuous, automatic regeneration across the full generator load range — so it works even when the genset runs at light hotel loads. The result: no hull staining, no diesel smell on the aft deck, and no oily slick around the boat at anchor.

Question 8

How does the SeaClean system work?

Accepted Answer

Exhaust leaves the generator turbo, passes through a pre-heater that brings gas temperature to the regeneration window, then enters a ceramic filter substrate that traps soot. A control panel modulates heater power proportionally to exhaust temperature, so soot is continuously oxidized to CO2 and ash. The system includes a manual regeneration mode and a high-back-pressure alarm output for integration with the yacht's monitoring system.

Question 9

What are the benefits of a custom-fabricated exhaust system?

Accepted Answer

Custom fabrication lets us match the engine's pulse tuning, route around real obstructions in the engine room, hit exact target back-pressure, and integrate insulation and structural mounts as one assembly. Off-the-shelf systems compromise on all of these and typically cost more over the life of the vessel in fuel, heat damage, and rework.

Question 10

What is a repower and do you handle the exhaust side?

Accepted Answer

A repower replaces the original main engines and/or generators with new units, often of different size, weight, or footprint. We coordinate with the engine dealer and shipyard from day one — taking 3D scans of the existing engine room, designing the new exhaust runs in CAD, fabricating, installing, and commissioning the system in sync with the engine swap.

Question 11

Do you handle generator exhaust differently from main engine exhaust?

Accepted Answer

Yes. Generator exhaust runs at lower mass flow but often at higher duty cycles (hotel loads at anchor), so muffler sizing, water-lift volume, soot management, and noise targets are different. Our generator systems are engineered specifically for marina-compliant noise levels and, when paired with SeaClean, for zero visible smoke and zero soot staining.

Question 12

How often should marine exhaust systems be inspected or serviced?

Accepted Answer

We recommend a visual inspection every 250 engine hours or at every haul-out, and a full survey (including bellows, lagging, hangers, mufflers, and water-lift) every 2 to 3 years or before any extended cruise. Wet exhaust components like risers, elbows, and bellows are wear items and should be replaced on condition, not on schedule alone.

Question 13

How much does a custom marine exhaust system cost in South Florida?

Accepted Answer

Pricing depends on vessel size, engine count and horsepower, materials (316L stainless, 321, AL6XN, Inconel, or 5086 aluminum), number of generators, whether SeaClean is included, and complexity of the run. A single generator wet exhaust replacement may start in the low thousands, while a full twin-main + dual-generator new build on a 100' yacht can run into the six figures. We provide a detailed line-item quote after a survey or drawing review — no estimating by phone.

Question 14

Do you offer free quotes and estimates?

Accepted Answer

Yes. Initial quotes based on drawings or photos are free. For complex retrofits we usually recommend an on-board survey by one of our engineers; we'll tell you up front whether a survey charge applies and credit it against the project if you proceed.

Question 15

What factors affect the price of a marine exhaust project?

Accepted Answer

The biggest drivers are material choice (Inconel is multiples of the cost of 316L), system length and number of bends, insulation type and thickness, muffler and water-lift sizing, classification society requirements, access into the engine room, and whether the work is performed at our Fort Lauderdale shop or by a mobile crew at your location.

Question 16

How much does SeaClean cost to install on my generator?

Accepted Answer

SeaClean pricing is sized to the generator kW rating and the available envelope in the engine room. Most installations fit within the generator's sound shield. Because each SeaClean install is unique and goes through class approval, we quote after reviewing your generator specs, exhaust drawings, and a brief survey — typically within a week of receiving the information.

Question 17

Do you offer payment terms for large projects?

Accepted Answer

For new builds and repowers we work on milestone-based progress payments tied to design approval, fabrication, delivery, and commissioning. We do not offer consumer financing, but we are happy to coordinate billing with your shipyard or project manager.

Question 18

What is your design and fabrication process?

Accepted Answer

Step 1: discovery call to scope the project. Step 2: on-board survey, 3D scan, or drawing review. Step 3: CAD design and back-pressure modeling, reviewed with the engine OEM and class society if applicable. Step 4: fabrication in our Fort Lauderdale shop with full traceability on every weld. Step 5: delivery and installation (in-shop or mobile). Step 6: commissioning, sea trial back-pressure verification, and handover documentation.

Question 19

How long does a typical marine exhaust project take?

Accepted Answer

A single generator wet-elbow replacement can be turned in a few days. A full custom twin-main exhaust system from design through commissioning typically runs 8 to 16 weeks depending on materials, class approval, and shipyard schedule. SeaClean installations average 4 to 8 weeks from approved drawings to commissioning. We always commit to a written schedule with milestone dates.

Question 20

What should I expect during an on-board service visit?

Accepted Answer

Our technician arrives with the tools, parts, and consumables for the scope of work, and protects the engine room with mats and containment before any cutting or grinding. We document the existing system with photos, perform the work, clean up completely, and provide a written job report with before/after photos and any recommended follow-up.

Question 21

Do you handle class society submissions and surveys?

Accepted Answer

Yes. We prepare design drawings, schematics, material certificates, and weld procedures, and submit them to ABS, Lloyd's Register, DNV, RINA, or other class societies. After fabrication and installation we coordinate the class surveyor's inspection through final approval — we have done this on close to 30 SeaClean projects alone with every major society.

Question 22

Can you work alongside our shipyard or refit team?

Accepted Answer

Yes — most of our projects involve a shipyard, a project manager, and other trades. We coordinate cut-out schedules, hot-work permits, lift planning, and commissioning sequencing with the yard so the exhaust work integrates cleanly with the rest of the refit.

Question 23

What materials do you use for marine exhaust systems?

Accepted Answer

316L stainless steel is our standard. We also fabricate in 321 stainless, AL6XN super-austenitic, and Inconel for higher-spec or extended-warranty work, and in 5086 marine-grade aluminum where aluminum is specified. Every component goes through nitric-acid passivation after fabrication to restore the chromium oxide layer.

Question 24

Why is 316L stainless steel the right material for marine exhaust?

Accepted Answer

316L resists chloride pitting corrosion from salt water and salt air far better than 304, and the low-carbon (L) grade resists weld decay in the heat-affected zone. It handles wet-exhaust temperatures, holds up against engine vibration, and is fully approved by every major classification society for marine exhaust use.

Question 25

When do you specify Inconel instead of stainless?

Accepted Answer

Inconel 625 is specified where exhaust gas temperature, sustained back-pressure, or sulfur content exceeds what 316L can tolerate over the design life — for example on military platforms, high-output diesels, dry exhaust runs near the turbo, and projects with extended warranty requirements.

Question 26

Are your welders and technicians certified?

Accepted Answer

Yes. Every welder on our floor is American Welding Society (AWS) certified, with weld qualifications specific to 316L and Inconel TIG. We maintain a 1,625-gallon Argon tank on site for atmosphere-protected welds, and all weld procedures, filler material lots, and operator IDs are tracked per component for full traceability.

Question 27

How do you ensure quality on every project?

Accepted Answer

We hold ourselves to Six Sigma / AIAG-aligned QA on commercial and military work, and apply the same discipline across all yachts. That means pressure and leak testing, weld inspection (including dye penetrant where specified), material certs on every length of pipe, and a documented commissioning checklist on every system before handover.

Question 28

Do you use premium and marine-grade materials throughout?

Accepted Answer

Yes — all wetted and exhaust-gas surfaces are marine-grade. We do not substitute carbon steel hangers, mild steel fasteners, or non-marine insulation. Bellows, V-band clamps, hose, lagging, and fasteners all come from marine-qualified suppliers we have used for decades.

Question 29

Do you offer marine exhaust service in Fort Lauderdale?

Accepted Answer

Yes. Fort Lauderdale is our home — our shop, engineering office, and primary service base are all at 3330 SW 2nd Ave. We service every major marina, shipyard, and boatyard in the area including Lauderdale Marine Center, Bradford Marine, Rybovich Lauderdale, Pier 66, Bahia Mar, and Las Olas Marina.

Question 30

Do you service Miami and Miami Beach?

Accepted Answer

Yes. We regularly dispatch mobile crews to Miami, Miami Beach, Coconut Grove, Key Biscayne, and the Port of Miami. Travel time from Fort Lauderdale is short enough that most Miami service calls are handled same-day or next-day depending on scope.

Question 31

Do you travel to Palm Beach and Boca Raton?

Accepted Answer

Yes. We work throughout Palm Beach County, including Rybovich West Palm Beach, the Palm Harbor Marina, Old Port Cove, Sailfish Marina, and the marinas in Boca Raton, Delray Beach, and Jupiter. Mobile service in the Palm Beach area is part of our standard South Florida coverage.

Question 32

Do you cover Stuart, the Treasure Coast, and the Florida Keys?

Accepted Answer

Yes. We regularly service vessels in Stuart, Jupiter, Vero Beach, Fort Pierce, and throughout the Treasure Coast, as well as Key Largo, Marathon, and Key West. Mobile crews bring everything needed for on-board diagnostics, parts replacement, and full system repairs.

Question 33

Do you provide service outside Florida and the United States?

Accepted Answer

Yes. Our mobile teams travel worldwide. We routinely send technicians to the Bahamas, Caribbean, Mediterranean (Monaco, Antibes, Palma, Genoa, Viareggio), Northern Europe (Amsterdam, Hamburg, UK), the Middle East (Dubai, Abu Dhabi), Asia (Singapore, Hong Kong), and the Pacific Rim (Sydney, Auckland). Logistics and customs are handled in advance so the visit is productive from day one.

Question 34

Can I bring my yacht to your Fort Lauderdale shop?

Accepted Answer

Yes. We coordinate dockage at nearby Fort Lauderdale yards and handle pickup and reinstallation of components at our 30,000 sq ft facility — including custom fabrication, machine work, weld repair, and passivation that cannot be performed dockside.

Question 35

How long does a custom marine exhaust system last?

Accepted Answer

A properly designed and installed 316L stainless system typically lasts 15 to 25 years on the dry side and 10 to 15 years on the wet side, depending on operating hours, fuel quality, water injection geometry, and how well the boat is laid up between seasons. Inconel and AL6XN runs can exceed 25 years.

Question 36

How do I maintain my marine exhaust system between service visits?

Accepted Answer

Visually inspect bellows, hangers, lagging, and the muffler shell at every oil change. Check for soot staining at overboard discharges (a sign of incomplete combustion or a failing wet elbow), look for water weeping at flanges, and listen for vibration or rattle changes. Flush the wet-exhaust side with fresh water before extended layup.

Question 37

How long does the SeaClean DPF last between service intervals?

Accepted Answer

SeaClean is designed for continuous automatic regeneration, so soot does not accumulate to the point of blockage. Routine service is limited to periodic ash cleanout (typically every 2,000 to 4,000 generator hours depending on duty cycle) and verification of the heater and control panel. We provide the service schedule with every install.

Question 38

Do you stock replacement parts for older D'Angelo systems?

Accepted Answer

Yes. We keep a fully stocked inventory of exhaust system parts for main engines and generators — silicone and neoprene hose, V-band clamps, bellows kits, turbo covers, gaskets, lagging, and hardware — and we can re-fabricate legacy components from our drawing archive. Urgent orders ship worldwide.

Question 39

What is your warranty on new exhaust installations?

Accepted Answer

Standard warranty is one year on workmanship and materials, with extended warranty options available on Inconel and AL6XN builds. SeaClean carries its own warranty on the heater, control panel, and substrate. Full warranty terms are included with every project quote.

Question 40

Are you licensed and insured?

Accepted Answer

Yes — D'Angelo Marine Exhaust is fully licensed and insured to operate in Florida and internationally. We carry general liability, workers' compensation, marine operators liability, and product liability insurance. Certificates of insurance naming a shipyard or vessel as additional insured are provided on request before any work begins.

Question 41

Which classification societies and industry bodies do you work with?

Accepted Answer

ABS, Lloyd's Register, DNV, RINA, ABYC, AWS, NMMA, IYBA, and MIASF. We prepare design submissions and coordinate inspections through commissioning for every class society listed.

Question 42

How much experience does your team have?

Accepted Answer

The company has built marine exhaust systems since 1986. Our six full-time engineers, our AWS-certified welders, and our field service technicians average over a decade each in marine exhaust specifically — not general fabrication. That depth shows up in faster design iteration, fewer field surprises, and systems that hit back-pressure targets on the first sea trial.

Question 43

Why should I choose D'Angelo Marine Exhaust over a local fabricator?

Accepted Answer

Because marine exhaust is the part of the boat most local fabricators get wrong. We are exhaust specialists — 38+ years on one product line, full in-house engineering, die-formed elbows, AWS-certified TIG welds in a controlled-atmosphere shop, the only patented DPF in the industry, and a documented quality record on Feadship, Westport, Viking, USCG Fast Response Cutters, and hundreds of other vessels.

Question 44

Do you have references or case studies I can review?

Accepted Answer

Yes. Our case studies page documents projects including the Detroit Eagle Feadship mega-yacht exhaust, the USCG Fast Response Cutter program, the Westport 50m retrofit, Viking sportfish repowers, and SeaClean DPF installations on dozens of yachts. We are happy to put you in touch with captains and project managers from completed projects on request.

Question 45

How do I get started on a quote or project?

Accepted Answer

Call us at +1 954.763.3005 (or toll-free +1 800.952.8555), email through the contact page, or send drawings and photos directly. For South Florida vessels we can often schedule an on-board survey within the week; for international work we'll coordinate logistics around your itinerary.
