Soundproof Your Inboard Engine And Generator
Advertisement
Save your voice and regain your floating peaceful refuge by adding soundproofing to your engine and generator.
The best strategy to address noise is by containing it at the source, a good example being the insulation inside this engine cover.
Time spent on the water should be relaxing. But that can be difficult when you have to scream over engine or generator noise during conversations or are left lying awake at night listening to the melodious hum of an air conditioning unit. Installing soundproofing can make a huge difference in onboard noise reduction. Here's how to transform the hullabaloo of your boat into the peace and tranquility of a floating Zen garden.
The best way to combat noise is by containing it at the source — within an engine compartment, for example. Soundproofing is perfect for this application, and while not fireproof, it is typically fire-retardant up to around 225 F.
Installation of a good quality foam soundproofing barrier can reduce engine noise by 10 to 35 decibels (about 65%). Soundproofing material is available in a wide variety of forms, from sprays and paints to foil-backed foam panels. Foam panels are a popular choice and one that's very effective against airborne noise pollution.
Soft sound shields, such as this one from GSI (stopthesound.com), provide both installation flexibility and significant noise reduction.
Self-adhesive panels are easy to install (just peel and stick), but you have to plan and position them exactly where you want them the first try as you typically can't reposition them without damaging the foam. Panels without adhesive backing require spray- or brush-on contact adhesives, which may allow a bit of last-minute repositioning, making them easier to work with in tight spaces.
Regardless of adhesives used, overhead panels require additional support from mechanical fasteners.
Regardless of the adhesives used, panels also require the use of mechanical fasteners (such as screws and fender washers) particularly for overhead horizontal installations.
Soundproofing panels can be cut to shape with a box cutter or razor knife, however a serrated knife blade will provide a cleaner cut of the foam material itself. Thin sheets of soundproofing material can also be cut with a pair of good quality scissors. To ensure the best fit (and avoid cutting snafus) make cardboard templates first to check fit and for use as a cutting guide. Be sure to dry fit everything prior to applying adhesives or peeling self-adhesive panels.
Use joining tape to seal and prevent sound "leaks" at panel joints.
When planning your installation, remember that sound flows like water, meaning you'll want to use Mylar seal or joining tape (typically provided by the manufacturer) to prevent "leaks" at panel joints. Cables and hoses penetrating the material should be sealed using tight-fitting rubber grommets, while access hatches should close snugly with a good, tight seal.
That said, any soundproofing installation must provide adequate ventilation for the engine. Required vents and air holes can be quieted using air baffles. It's not realistic to expect all noise to be eliminated once soundproofing is installed, but when done correctly, you should be able to carry on a conversation at normal volume levels. After all, who wants to yell when you are trying to relax?
Soundproofing Installation Tips
- Read all instructions for the soundproofing, adhesives, and mounting hardware prior to starting your project.
- Make templates to check fit prior to cutting panels. Be sure to allow for material thickness at corners.
- Ensure your installation provides adequate ventilation and keeps insulation material above bilge water levels. (Avoid exposure to any wet areas.)
- Provide a minimum clearance of 6 inches between soundproofing and engine or generator exhaust manifolds.
- Use sharp tools when cutting soundproofing, both to produce clean cuts and to avoid tearing of reflective foil. The foil or silver facing side should face upward when cutting.
- Handle soundproofing material carefully. Avoid folding the material back on itself, which can result in creasing.
- Seal all exposed edges, joints, and corners with Mylar seam tape to prevent water or other contaminants (such as fumes or oil) from entering and degrading the soundproofing material. Seam tape can also be used to provide chafe protection at wear points. You can purchase it at most marine stores.
- Don't rely on adhesives alone. Use fasteners and fender washers where appropriate (all overhead and vertical surfaces) to ensure backup in the event of adhesive failure.
- Apply adhesive for and install one panel at a time. Install the top panel first, which lets adjacent vertical panels provide support to the outer edges of the top panel.

The Best Guide to Soundproofing a Boat Engine Compartment
Sailing on a boat can be an exhilarating adventure. Nevertheless, loud engine noise and vibrations can spoil the enjoyment. Luckily, this guide presents methods to soundproof the boat engine compartment.
In this article, I’ll show you how to fix this problem. But before we proceed, it’s essential to identify the reasons for the uncanny noise from your boat’s engine so you can know what solution to apply.
Also, read these Handy Tips on How To Quiet Your Boat
Why Is My Boat’s Engine So Loud?
As an affiliate, I may collect a share of sales or other compensation from the links on this page.
If your boat’s engine is loud it may be due to a malfunctioning exhaust or a wrong propeller pitch. However, new boat engines can also be loud due to a lack of sound insulation.
New engines can be annoyingly loud. This in no way implies that the engine is defective. A new fiberglass boat has little to no sound insulation.
There’s also the issue of the propeller pitch. Installing the wrong propeller will affect the boat engine’s revolutions per minute (RPM). RPMs over 4,800 are bad for your engine.
A bad lubricant or gasoline identified by the engine sensors might also impact propeller pitch, causing the noise levels to rise. Listen to every sound, especially the one coming from your engine room, when sailing your boat.
Ensure you fix these problems before you resume sailing on your boat, as high noise levels are not suitable for your health, boat, and even aquatic life.
Soundproofing a Boat Engine Compartment – Step by Step
Here’s how to reduce noise in your boat’s engine compartment:
- Service your boat’s engine.
- Replace the engine propeller.
- Seal all openings except the vent.
- Isolate vibrating parts.
- Install a soundproof material in the engine’s compartment.
- Line the walls and ceiling of your boat’s engine room with soundproofing materials.
1. Service Your Boat’s Engine
This step is the first and most important. Before you go on sealing compartments, you must ensure the engine is in good condition. If the engine fails, there’ll be no boat ride after all. Get an expert to check the engine. Change lubricants if necessary.
2. Replace the Engine Propeller
If the wrong propeller is installed, you’ll have a lot of noise from your boat’s engine. The propeller is responsible for your boat’s revolutions per minute, affecting the noise. The simple solution is to replace the propeller with something more adequate.
3. Seal All Openings Except the Vent
Seal all areas that allow sound passage except the vent. You don’t seal the vent because, like every other system, the engine needs air to function properly. Using a soundproof material, seal the following places:
- Panel joints
- The spaces left by wire connections
- Pipes that lead outside
- The areas that lead from the engine room like the Lafayette
- Every single slight opening except the vent
4. Isolate Vibrating Parts
When two items collide or an object rattles, vibration occurs. Use light materials to separate solid objects that could collide in a boat engine compartment or use it to isolate concrete elements to reduce vibration. The light material allows the solid section to move while keeping the vibrations contained.
5. Install a Soundproof Material in the Engine’s Compartment
Sound absorption materials like foam-backed material and vinyl can help reduce noise inside a boat engine’s compartment. Insulating the engine compartment will reduce and absorb noise from the engine room. In addition, spread a waterproof carpet over the engine to reduce noise and keep water out.
6. Line the Walls and Ceiling of Your Boat’s Engine Room With Soundproofing Materials
You can use soundproofing materials such as 1-inch foam-backed cloth (foam spray) or perforated vinyl headliners to cover your boat’s walls and the ceiling of your boat’s engine compartment. Take a step further by covering the engine bay with these materials.
Adverse Effects of a Boat Engine’s Noise and Vibration
Constant exposure to engine noise and vibration can harm you and your boat. Some of these effects include:
- Boat squeaking
- Disruption of aquatic life
Let’s analyze these points below:
- Deafness: Noise is measured in decibels (dB). The human ear can tolerate sounds below 85dB. Sounds from 100dB and above can cause deafness. A loud boat engine produces sounds of up to 100dB. Constant exposure to sound at this level can damage your ear.
- Boat squeaking: Constant boat vibration can loosen fasteners and other weak sections of the boat. Those components will begin to squeak and make various unpleasant sounds. This can reduce the boat’s lifespan and even make a new boat appear old.
- Disruption of aquatic life: Boat Engine sounds affect the coral reef, stimulating erratic behavior in adult fish. Enraged adult fish can start attacking other younger harmless fish. This results in a higher rate of mortality in aquatic life.
How To Maintain Your Boat Engine and Prolong Its Lifespan
Boats are pretty expensive, so It’s pointless to spend money on a boat only to have the engine fail after a year or two. Here are five suggestions for extending the life of your boat engine.
- Warm up your boat regularly. Your boat’s engine can become cranky if you leave your boat for weeks or months without warmups. If you’re not taking the boat out, turn on the engine and let it rev for a few minutes now and then.
- Cruise more often. The longer you leave your boat’s engine idle, the weaker it gets. If you can afford it, cruising regularly keeps the boat’s engine alive and responsive.
- Keep fuel and oil fresh. Check your fuel and oil levels regularly.
- Regularly flush out salt water . Saltwater is bad for your boat’s engine. So you must always thoroughly flush immediately after sailing on salt water.
- Cover your boat. As simple as it sounds, it can be a burden. Always cover your boat when not in use. A boat cover will keep many unfavorable factors out of your engines, such as harsh weather and dust.
Cruising on your boat can be a delightful experience, but the noise and vibration from the engine compartment may spoil the fun.
Take simple measures in sealing up your engine room and engine compartment to reduce the noise so you can enjoy your time on your boat.
Developing a maintenance culture will keep your boat’s engine in good condition and help prolong its lifespan.

Yachting Monthly guidelines for installing marine engine soundproofing
Duncan Kent’s full report on how to choose the best marine engine soundproofing for your yacht, can be read in the June 2014 issue of Yachting Monthly .
Guidelines on installing marine engine soundproofing: Foil/cloth and hard barrier soundproofing is best cut with a sharp modelling knife – but it’s easier and neater to cut the foam using a serrated blade. Thinner sheets cut well with good scissors.
Self-adhesive sheets are easy to peel and attach, but you must position it correctly first time. Plain-backed types require spray or brushed contact adhesives – the latter being more controllable in tight spaces. Mechanical fixings should be added to all horizontal upper surfaces.
Suppliers advise that all joints are covered using special joining tape to avoid ‘leakage’. Self-adhesive foil tape works excellently on foil-covered material, but white plastic tape from Vetus will peeled off easily.
Ideally, soundproofed bulkheads should totally encase the engine area, separate from any tanks, which can resonate - amplifying the sound. Engine noise can ‘flow’ along the bilges, so where possible bulkheads should continue down to the hull, leaving only limber holes for bilge water.
Remember to provide enough airflow for combustion. Open air holes will ruin the insulation, but a simple baffle will stop most of the noise escaping.
Finally, all cables and pipes should pass through snug-fitting rubber grommets, while any covers or side panels should fit snugly with a noise-tight seal.

Marine Insulation…
With 36 years of experience of producing acoustic materials for Soundproofing and Noise reduction, we have the perfect solution for your marine acoustic problems. Our marine insulation products are ideal for sound-proofing boat engine rooms and controlling noise and vibration problems. Acoustafoam’s Class O composite products offer the best possible acoustic result especially for engine room sound insulation due to the multi-layer combination.
Acoustafoam laminates are used in many industrial applications but mostly used for the marine industry engine room noise problem areas.
Acoustafoam Laminates have three layers in addition to a protective facing for cosmetic and practical functions:
The Absorption Layer
A thick layer of 25mm fire zero rated Class O foam which soaks up noise and stops it bouncing around the engine compartment.
The Transmission Layer
A high-density 5kg per square metre polymeric barrier that provides the highest possible mass for the job of transmission loss (stops noise from getting through to other areas of the boat at the application wall).
The Isolation Layer
This 6mm layer of foam has a crucial function, it acts like the gap in double glazing and stops the noise that hits the transmission layer being carried through to the bulkhead.
Acoustafoam Marine Laminates can be supplied with a range of facings. PU Films Black and White, Glass Fibre, Aluminium Coated Glass Fibre, Aluminium Foil, Fire Rated Fabrics or a range of Sprayed Fire Rated Paints.
Acoustafoam offers a standard variety of products for marine insulation applications. Sheets 990mm x 590mm x 32mm – 4 sheets per box with a self-adhesive backing. Installation is easy. Simply cut the material to shape, peel off the release paper and fix to the affected area. Use Acoustafoam jointing tape to seal butt joint edges.
Acoustafoam manufactures marine acoustic insulation made from Rockwool fire pro.

Let us help. 206-632-4462. Email. Silence the noise & create a peaceful trip! Fisheries Supply offers marine sound insulation, soundproofing foam & engine compartment insulation for all boats.
