FAQ

You can find the service prescriptions in your own Maxwell manual! Manuals can also be downloaded from the Maxwell Marine website: http://www.maxwellmarine.com/support_manuals.php

You will find the nearest VETUS selling point in our online dealer locator. They will advise you on how to hand in your moulds and drawings.

Yes, the profile is available in various colours upon request.

Yes, the Marex windows with aluminium profiles are a good alternative when replacing windows with rubber-sealing profiles and hardly no adjustments have to be made in in the hull/superstructure of the boat.

Marex offers various solutions for specific applications. Your VETUS dealer will provide you with detailed information.

Yes, VETUS calorifiers are suitable for both horizontal and vertical mounting.

EMR stands for Electronic Motor Regulation and is available for the DT(A)44 and DT(A)66 engines. The functions of the engine are now electronically controlled instead of mechanically.

A waterlock collects the cooling water present in the exhaust system when the engine has stopped, helping to prevent water ingress into the engine and thereby preventing damage to the engine. In addition a waterlock reduces the exhaust noise considerably.

An exhaust transom outlet must always be fitted above the waterline. We advise a minimum distance of 5 cm between the waterline and the lowest part of the exhaust transom outlet.

Providing that the engine is also above the waterline. Remember, the waterlock must always be lower than exhaust outlet on the engine.

We highly recommend the use of an exhaust temperature alarm. Not only this may save your boat but also your life. If the water injection is blocked for whatever reason the alarm will go off and the issue can be fixed before it has created serious problems for the waterlock and the engine.
If you want to be extra save, please have a look at our HD-line waterlocks. These can even withstand uncooled exhaust gas for more than 10 minutes! This would give you extra time to react to the alarm.

Air vents fitted with a valve require periodic maintenance in order to prevent blockage. The valve should be removed and washed out with fresh water. Air vents fitted with a bleed hose to the hull of the boat do not require periodic maintenance.

Model type ASDV can be removed by hand and no tools are necessary. Model AIRVENTV requires a crosshead screwdriver.

To choose the right hose diameter you have to know the allowable back pressure and power of your engine. By filling in our calculation tool [link] the hose diameter can be calculated. You also need to know how much capacity you need. This can be calculated with the hose diameter and the hose length that is used in the installation.

The key for a good functioning and noise reducing exhaust system is to find balance between blocking the noise without obstructing the flow and therefore increasing the back pressure. All the Vetus waterlocks and mufflers are designed and tested to create this perfect balance. Knowing this, you can imagine a waterlock with the revolutionary 3 chamber technology (NLP3) is more noise cancelling than a NLPH, and an installation with a muffler is more noise cancelling than one without.

A “Dry” exhaust system causes a tremendous amount of noise and diesel exhaust smell. A diesel engine can easily produce an exhaust gas temperature of 600 ˚C or more. Applying a wet exhaust system would not only better reduce the exhaust noise than a dry exhaust system, it also reduces the exhaust gas temperature to about 40 ˚C to 50 ˚C by injecting the engine cooling water in to the exhaust line.

With a synthetic waterlock you avoid corrosion issues, also it is resonance-reducing which results in less noise. With the rotatable hose connections we make the waterlock easy to fit into different installations. Many waterlocks in the VETUS program are also available in HD Navidurin material. This material outperforms GRP.

No that’s not necessary, the exhaust product line is large and can be used for a lot of different engines. Of course we highly appreciate it, if you would choose a Vetus engine. Did you know that Vetus engines come with a unique 5 year warranty?

This has been caused because the engine did not get sufficient cooling water. Reasons for this include; a damaged pump impeller, a blocked cooling water strainer or inlet, or the inlet seacock being closed.

Yes, this is possible by means of the interconnection kit FTLD.

VETUS tanks are lightweight and easy to install. Condensation and the risk of corrosion does not occur. Another advantage is the fact that you are always able to see the amount of fuel that is in the tank.

Yes, that is possible. Besides excellent protection they are also easy to install.

No, the VETUS no-smell filters are only suitable for use with diesel tanks.

A double wall calorifier will heat up approximately 5- 7 times faster than a conventional spiral coil model. In addition, the water will stay hot longer due to the heated double wall and the thick insulation foam. All VETUS calorifiers are equipped with a double wall.

The inspection lid on the tank makes it possible to clean the tank easily.

Yes, this is usually possible, providing the leak is quite small. You can order a repair kit – code REPSETWT from your VETUS dealer.

This is absolutely harmless and is caused by the smell from the hoses. Sterilise the tank and hoses on a regular basis using fresh water and chlorine tablets or white vinegar. Please see the tank fitting instructions for full details.

Yes, this is possible. You will have to replace the connections for ones which are suitable for use with diesel fuel.

No, a waste water system is not obligatory (yet), but it is also not allowed to pump black waste water into the harbour or marina. A VETUS waste water system is therefore certainly recommended!

Yes, this is no problem. All VETUS marine toilets are available for 12 or 24 Volt supplies and some models are available for 120 Volt or 230 Volt AC.

You need to make sure that the run of the discharge hose will not allow waste water to remain in the hose after pumping. This may cause a noxious smell to permeate through the hose. Moreover the system needs to be rinsed on a regular basis.

The carbon impregnated elements in this filter need to be replaced once a year.

We advise the use of a membrane type pump. These are capable of moving both liquid and semi-solid waste without blocking and the pumping action helps to break up the waste.

The rule of thumb for calculating this is described on page 200 of the VETUS catalogue. Alternatively, please contact your VETUS dealer who will be pleased to advise.

No. Due to the wide range of different panels available, these are not included and need to be ordered separately.

This electronic delay eliminates the risk of the bow thruster being switched from one direction to the other before the motor has stopped rotating. It will prevent wear and tear to the drive leg and avoid motor damage.

VETUS bow thrusters are equipped with a switch off safety device. This device sees to it that the bow and/or stern thruster is switched off automatically after more than 2 minutes of continuous running. As from 2011 this device is provided as a standard.

Yes, it is, by means of the RCM radio control.

The correct hydraulic oil is VETUS code VHS1 and can be obtained from your VETUS dealer.

We recommend ISO 3448, VG 320, SAE 90, weight gear oils. Vetus oil order number VBT

In the Vetus catalogue you will find a selection chart for windlasses and capstans. The required windlass are related to a standard chain and rope size. You can also visit http://www.maxwellmarine.com/gen_which_winch.php?selection for more information.

The RCM2 or RCM4 are hand held wireless control units, to be used for control of a bowthruster, windlass, and other different electronic equipment

While anchoring you need to secure the chain with a chain stopper [for rope a bollard]. Because all circumstance can be different while anchoring and you never know how much force is on the chain at certain moments. A chainstopper is able to hold much more loads as the windlass.

In the latest catalogue, we have a section advising you how best to ascertain which windlass is best suited to your boat and your requirements. If your boat is in the 6 meter (20 feet) to 20 meter (65 feet) range, then the Power & Sailing Boats catalogue should provide you with most of the background information you need. If you are fortunate enough to be considering the most suitable windlass for your Superyacht (vessels generally over 25 meters (80 feet), then the “15 Easy Steps to Windlass Selection” chart in Maxwell’s Superyacht colour catalogue should provide you with the information you need. Should you require further assistance with your windlass selection please do not hesitate to contact Maxwell or any of their representatives world wide. Contact details can be found under the ‘Find Us’ section of our web site.

There are many nautical terms associated with the anchoring of your boat. Winch and windlass are but two. To acquaint you with many of the commonly used terms associated with lowering and raising your anchor, we have provided a Glossary of Terms in both our Power & Sailing Boats and Superyacht catalogues. These terms can also be found under the Support section of our Website. Click ‘Glossary’. For those of you who really want to get into marine nomenclature there is an excellent book available called: “The Oxford Companion to Ships and the Sea”, Oxford University Press

Maxwell manufactures both. Refer to the “Which Winch” section of our Website under Power & Sailing Boats or check Superyacht headings for more information regarding which type will be most suitable for your boat.
