How can I reduce engine vibration & noise?

Isolating the engine from the rest of the boat effectively leads to the control of vibration, sound and noise on board to ensure a smoother running, quieter vessel.

A quiet boat stops the noise in the engine room and the Halyard Aquadrive anti-vibration system has a long-established history of reducing boat engine noise at source.  It can reduce structure borne noise by 50%.

Reduce engine noise with anti-vibration mounts

Engine mounts are a tiny part of the vessel, but they do have a significant effect on the enjoyment experienced aboard by controlling vibration and noise levels on a boat.  The Halyard Aquadrive anti-vibration system uses soft vibration absorbing mounts which the engine sits upon, providing far reaching benefits that belie their size. 

How do anti-vibration mounts reduce marine engine noise?

An engine vibrating on soft mounts needs total freedom of movement from its driveshaft if the noise and vibration are not to be transmitted to the hull.  In comparison, traditional engine installations demand very stiff mounts which send elevated levels of vibration to the hull.  Vibration becomes unwanted noise.

How to significantly reduce marine engine noise

The Halyard Aquadrive anti-vibration system:

  • uses a constant velocity driveshaft which isolates engine vibration and eliminates the need for exact alignment.
  • uses a thrust bearing that transfers the load of the propeller shaft to the hull and stabilises alignment
  • uses softer steel hooded mounts to keep engines in place even if vessel turns over
  • Improves the overall engine installation and reduces vibration/ noise on a boat significantly

Turn marine noise problems over to the professionals

The team at Allboat Services has the experience to help you choose the right Halyard Aquadrive anti vibration system for your engine, whatever its size, hp or weight.

How can I reduce boat noise?

Sound insulation options from Halyard will reduce irritating, distracting and annoying airborne, engine noises to provide soundproofing barriers from the engine, hull structures and cabins, which are all sources of common complaints.  They absorb sound and prevent the noise from transmitting through the bulkhead, interrupting the transmission of sound.  They will also dampen sounds caused by wave and water slapping which can make sleeping difficult.

Why is my boat so loud?

A noisy boat can drive everyone on board crazy and ruin the boating experience.  Halyard sound insulation products can reduce noise transmission when the engine is running or when the boat is docked to improve sound quality and comfort on board. 

How do I improve the noise levels and make my boat quieter?

Halyard soundproofing solutions will make your boat a peaceful place where you can relax and unwind, and do not have to shout to be heard.  Extremely tough, sound Insulation from Halyard repels fluids, is resistant to fuel/oil spills and most importantly has excellent fire safety standards, meeting the requirements for flammability.   Absorb irritating noises on board your power boat, pleasure craft, commercial vessel and yacht with Halyard!

What exhaust accessories help reduce noise on a boat?

Halyard creates silencing and exhaust system components, fittings, hardware and accessories that make exceptionally quiet exhaust systems to reduce noise and the sea sickness caused by noise and vibration.

Halyard water separators for marine generators completely remove the irritating noise of water sploshing out of the exhaust, minimise back pressure and reduce the exhaust noise from generators running in quiet anchorages by up to 80%. 

When excellent acoustics and good temperature resistance are paramount – lift silencers are used to reduce noise for engines positioned on or below the water line.

Bespoke and standard transom exhaust fittings

Whether you require a standard or bespoke solution, minimise the risk of damage when manoeuvring a craft with through hull transom exhaust fittings.  Available in stainless steel finish they fit a range of exhaust hoses sized from 44mm (1.75”) to 304mm (12”).

What is the best water filter for drinking water?

Wave International provides filters, filter systems and easy connect cartridges which offer a range of practical, point of use cooking and drinking solutions that ensure great taste and convenience direct from your tap!  The different Flostream models have different flow rates:  The Flostream has a flow rate of 1 litre per minute, the Flostream Hiflo delivers 6 litres per min and the Flostream Hiflo1- supplies ten litres per minute.  The filters use cartridges that last up to 7600 litres, approx. twelve months, depending upon size and usage.

How to improve the quality of on-board drinking water

Always drink clean, fresh, safe and palatable drinking water on-board your vessel with Wave International’s point of use filtration and Hiflo systems.  Flostream provides premium quality drinking water direct from your water tank.

How to improve the quality of drinking water

Eliminate lead, heavy metals, chlorine, cyst, hormones and harmful bacteria from your drinking water with Flostream drinking water filter systems which have inbuilt bacteriostatic control to ensure there is no risk of micro bacterial growth in your water system.

Is there an alternative to drinking bottled water on board?

If you want to stop having to store and use bottled water on board your boat, you can reduce reliance on single use plastics and negate the health concerns of drinking bottled water by using the Flostream drinking water filtration system.

The Flostream drinking water filtration systems provide food service quality water.  It filters out chlorine, odours and impurities as well as reducing limescale and bacteria growth.

Wavestream Bilge Filters to create cleaner seas and waterways

Wavestream bilge filters remove pollution from the bilge discharge water of all boats and, available in a variety of sizes, ensure all boats including powerboats, yachts, superyachts and fishing boats are compliant with the five parts per million regulation of the Boat Safety Scheme.   Awarded Lloyd’s Type approval, Wavestream bilge filters keep our seas, inland waters, marinas and harbours cleaner by ensuring that only clean and fuel/oil/grease free water is discharged overboard.


What’s the distance I need from the sprayhead to the silencer?

Halyard recommends a 300m vertical distance from the dry section of the sprayhead to the top of the silencer. If in doubt contact a Halyard representative.

How do I prevent overheating the exhaust?

The HMI Exhaust alert kit is an essential safety product that is compatible with all water-cooled exhaust systems and alerts the user to an overheat situation QUICKLY and BEFORE serious and expensive thermal damage occurs to the exhaust system, engine and vessel.

How does a marine exhaust temperature alarm work?

Be warned BEFORE damage occurs:  The Halyard exhaust alert system reacts immediately once the flow of injected water stops to provide an instant overheat warning via an audible and visual alarm. 

Early warning sensors are positioned in the exhaust hose  after the water injection unit.

What causes a marine exhaust to overheat?

If water flow is cut off by a plastic bag/seaweed being sucked into the intake or by a water pump problem, the exhaust temperature will rise to over 450 degrees C, when marine diesel exhaust systems are only designed to take temperatures of 85 degrees C.

How do I prevent overheating the exhaust?

The HMI Exhaust alert kit is an essential safety product that is compatible with all water-cooled exhaust systems and alerts the user to an overheat situation QUICKLY and BEFORE serious and expensive thermal damage occurs to the exhaust system, engine and vessel.

What marine exhaust alert system should I use?

Designed for use on single engines, twin engines or twin-engine craft with generators, the Halyard exhaust overheat warning system notifies the user if the exhaust system exceeds a safe operating temperature.  The 52mm diameter display control unit is waterproof to IP67, available in attractive finishes (chrome or black bezels and black or white gauge cards), requires no additional control box and can be fitted anywhere – the flybridge, cockpit or helm.

How high should I position my water separator?

A Halyard water separators should be at least 450mm above any given waterline to ensure
