Thinking about a boat?

There is so much enjoyment to be had when you are out on the water. It can be a very exhilarating time or even the most relaxing time, depending on your moods and requirements. Some like the wind and thrill of actually sailing, others find their enjoyment from fishing or water skiing and others just like to find themselves. Whatever your dreams are, be sure to select the right type of boat for you.

Sail or power? Catamaran or RIB? There are so many types of boats out there.

A good moto is try before you buy.

Consider what size of boat you would need – is it just you and a friend or will family be involved? Children or animals onboard? Will it be a day tripper or for longer periods? In which case, you might need something with more than one cabin.

Make sure you set yourself a clear budget, stick to it and also take into account there maybe additional costs that you may not have considered or factored into the purchase.

Don’t just look at the aesthetics or colours but take a close look at the engine/s, electrics, piping, plumbing, sails, etc. Expect some work will need to be carried out on second hand boats on things that you cannot see. It may be prudent to have an expert look over the engine and engine systems for you. MES Ltd offer an engine inspection service and we can also follow up, if you decide to buy the boat, with a “know your boat engine” lesson. This will make it safer for you once setting out on the water to enjoy your free time.

Good luck with your buying.

Boat parts UK

The legal bit to consider.

When you buy a boat you have a contract with Agreement, terms and conditions etc. The seller must prove clear ownership of the boat with a title for the boat. They must also have a VAT invoice to show that VAT on the boat has been duly paid.

If you ate buying a boat that is newer than  June 1998 and sold within the UK it must have a Recreational Craft Directive (RCD) – effectively a CE mark – which ensures the boat is built to a required standard.

If you buy a boat from the States and ship it across and it doesn’t have an RCD then this can be done retrospectively at a cost.

Boat Cleaning Tips

Boat Cleaning Tips

Just as much as you love to take a shower after being submerged in sea or lake water your boat will too.

There are good reasons to keep your boat clean and it’s not just for aesthetics. Clean and smooth surfaces help to reduce friction from the water and thus make you boat ride smoother and faster.

So what should you look out for:-

Choose your boat cleaner carefully

Use cleaners that have been manufactured for the job in hand. For example you may need either an overall boat cleaner, specific rib uv cleaner and protector, gel coat de-stainer, UV was polish or protection and cleaning your vinyl. This prevents damage to the finish on you boat.


Give your boat a rinse to remove loose dirt and grime prior to the proper wash.

Wash the hull

Use water, appropriate boat wash and soft clean sponge. Wash the boat including all the corners, under seats and difficult to reach places.


 Starting at the highest point and working your way down the boat rinse the boat fully to remove all of the soapy water.

Dry your boat

Use a clean soft cloth to dry your boat for a streak-free finish.


Now it is time to apply a wax to your boat. Use a wax with a UV protector to help protect your boat from sunlight

Clean canvas and vinyl

Use a suitable cleaner to remove dirt etc from canvas and vinyl furnishings

Whether this is the your first winter with your new boat or you are a seasoned sailor, we have put together a simple list of tips as an aide memoir. Hours spent now storing your boat properly can save you significant time and money for the new season. The main aim of storing your boat properly in the UK during the winter is to mitigate against the effects of our climate – cold and damp. If you are not going to use your boat for a prolonged time check out below our five handy tips.

Protect from the elements

  • Consider storing your boat under cover Boat indoor secure storage
  • Protect your boat from the winter weather with a good fitted cover over the cockpit.
  • Remove sprayhoods, dodgers, sail covers and sails.
  • If you are leaving the furling headsail on, check that it is secure so that it does not whip itself free and cause damage.
  • Double up your mooring lines if you are leaving your boat on the water. If one fails you have a backup for your boat.
  • Check your boat for leaks and also check the bilge pump is working properly.

Drain water from the system

  • Drain the water from your boat bilges and empty your water tanks.
  • Empty the water system.
  • Check your bilge pump is working.
  • If you have a flexible water tank, remove it and take it home to clean and sterilize it.
  • Empty water heaters and calorifiers.
  • If your boat remains out on the water during the winter ensure seacocks are firmly closed and not leaking.
  • If your boat is out of the water either in storage or on hardstanding or trailer the seacocks should be left open.
  • The gas should be turned off.

Prepare your engine

MES Ltd offer a winterisation service for either petrol or diesel engines. This can include inhibiting raw cooling system, protecting cylinder block, checking anti-freeze strength, inhibiting cylinder bores, protecting electrical components, preserving engine and gear box casing, checking batteries, adding fuel stabilzer.  Winterisation not only helps protect your boat engine from the extreme cold but it also helps maintain your engine from corrosion and internal damage.

  • It is a good idea to fill the fuel tank to a maximum and adding fuel stabilizer to help prevent build up of fuel bug.

You can either have a service carried out by MES Ltd at the same time as the winterisation process or wait until the next season for your service.

Fuel stabilizer

Remove as much as you can 

  • If you can it is best to empty as much as possible from your boat over the winter. Clothing, cushions and soft furnishings are particularly susceptible to damp weather which can cause mould.  
  • If you do not have storage space at home and have to leave them on board, make sure the air can circulate around them.
  • Remove the valuables like chart plotters or handheld VHFs.
  • Batteries lifetime will decline more quickly from being exposed to the cold so if they are not used for your bilge pump it is a good idea to also remove them.
  • Check and test your lifejackets.
  • Check flares are still in date and stored appropriately.
  • Having a clear out and clean now will make the new sailing season easier and can help you to spot any issues with your boat

Ventilate, dehumidify and heat

  • Damp air is the cause of mould and mildew and the best way to combat this is to ensure there is good circulation of air. So rather than battening down leave your hatches ajar so that the air can circulate around your boat. Mould and mildew not only leaves a bad smell it can also cause respiratory problems. Prevention is far better than spending hours trying to clean it up. You could also invest in a dehumidifier or other forms of moisture absorbtion.
  • Leaving your boat with as little moisture on as possible (see draining water tip) and leaving lockers etc, ajar can help keeping your boat mould and mildew free.
  • If you have power to your boat a small heater maybe an option to consider together with a dehumidifier. (Make sure your dehumidifier drains into a sink so you don’t have to keep going back to your boat to empty it). 

The above is a basic list of what to do when your are not going to be using your boat for sometime. You may also need to consider your insurance cover is the correct level for your boat and checking your boat periodically.



Why use fuel filtration?

Fuel cleanliness problems can cause costly damage to engine and components. Filtering the fuel before it enters your engine makes economic sense to help prevent impurities from damaging internal engine and its components.

Over the years engines have been modernised to provide us with higher horsepower, improved fuel efficiency and greater reliability. The modernisation has resulted in having to increase the pressure and tighten tolerances in order to achieve the desired outputs. Contamination from both organic and inorganic material including water enters the fuel. These contaminations are one of the main reasons that engines and its components can fail.

Thus being able to finely filtrate the fuel prior to entering your engine and its components is key to reduce component wear and also to optimize engine power.

MES Ltd are proud to be an authorised dealer for Fleetguard filters. These filters can be cross referenced to your engine filters.

Why choose Fleetguard?

Fleetguard filters are part of the Cummins family. They work with Cummins during design and manufacturing process to ensure their filters meet the highest standards. They meet and exceed OE standards for optimum protection and therefore reducing operation costs. Fleetguard innovative technologies means cleaning fuel to ISO 22/20/18 to ISO 18/19/19 and better.

Fleetguard filters also come with one of the most inclusive and comprehensive warranty in the industry. 

Fleetguard filters has over 8,300 products for air, oil lube, fuel and hydraulic filters.

Oil filters for boat engines

Oil filters for boat engines

Why are oil filters important to your boat engine?

The purpose of oil filters is to remove contaminants from engine oil and lubricating oil. This helps the oil in your engine to last longer increasing the time required between oil changes. The oil in your boat engine is there to increase the life of your engine by providing lubrication to the moving parts within the engine.

Types of Oil Filters

There are several types of oil filters that remove contaminants from the oil in slightly different ways.

The mechanical design uses either pleated filter paper or cotton waste. Contaminants build up on the filter paper which will eventually restrict the amount of oil flowing through the engine system. The build-up of contaminants will be the determining factor for when to change this type of oil filter.

The cartridge or spin-on type are basically a self-contained filtering system. They can either be mounted on the engine or remotely with supply and return pipes connecting the oil filter to the engine system. These filters have a permanent housing which contains the oil filter element. The spin-on filters make changing the filter much easier and less messy and is the most popular oil filter used on many engines.

Other types include magnetic, sedimentation, centrifugal and high efficiency. These however are less common types of oil filters.

MES Ltd stock a wide range of oil filters and we are able to obtain manufacturers oil filters for your boat or the equivalent Fleetguard filters. These Fleetguard filters have their own warranty. Contact us on 01248671215 or 07798572664 or email [email protected] for your oil filters, oils and much more.

Replacing a Cutlass Bearing on a Boat

Replacing a Cutlass Bearing on a boat

Boats with a conventional propeller that is shaft driven, use a Cutlass Bearing to support the propeller shaft and allow it to rotate whilst being cooled and lubricated by the surrounding water. The bearing is normally made up of an outer brass shell with a rubber inner. The condition of the bearing should be checked every time the boat is lifted out of the water for wear. Checking the condition of the bearing can be done by trying to lift the shaft by the propeller. If there is lift or play in the bearing which can either be seen or felt then this will mean that the bearing should be changed.

Replacing the cutlass bearing is not a technical job, however, it does require a bit of planning and 2 or 3 special tools.

The bearing can be located in 2 or the 3 different ways. In this blog we are going to look at a typical yacht with the bearing located on a P bracket or strut that is suspended from the hull.

A special tool exists that can remove and replace the bearing without the need to remove the propeller shaft from the boat. This tool saves both time and money if you are paying to have the job done. However, the cost of the tool could be prohibitive to a single boat owner. Here, at Marine Engineering Services (MES Ltd) we have this tool and so it may be more prudent to contact us to complete the job for you.

To replace the bearing without the above-mentioned specialist tool will mean that the propeller will need to be removed using a puller. Once the propeller is taken off the boat, the top end of the propeller shaft will need to be disconnected from the gearbox coupling. The shaft can then be removed from the boat.

Note at this time that the bearing is often held in place by grub screws in the P bracket. The bracket will need cleaning up and the screws, if any, removing. Be careful not to damage the screws. You should use the correct tool and an impact driver to free them.

With the screws removed, the old bearing needs to be cut through its length using a hacksaw or reciprocating electric saw. Care needs to be taken not to cut through the bearing into the P bracket or strut. Note only one cut will be needed if the grub screws were used to secure it. If you make the cut just above or below where the screw is located, you can screw in suitable screws to force the bearing to collapse in on itself near the cut you made with the saw. Once collapsed in, you can twist and pull the bearing out with some grips. If no grub screws were used to hold the bearing in, then 2 saw cuts opposite each other will be needed to free the bearing so that it can then be pulled out.

The P bracket should be cleaned where the bearing lies and the new bearing lubricated with soap on the outer case ready for installation. A length of suitable threaded rod will be needed, along with nuts and thick washers, in order to pull the new bearing into place. The thickness of the rod should be at least a 14 mm thread. Insert the rod through the P bracket and bearing fitting the washers and nuts either end. Tighten the nuts to pull the new bearing into the P bracket. Take care to keep the bearing in line with the housing at the start of this process and lubricate the rod nuts and washers with grease before using them.

Once the bearing has been pulled all the way in, remove the rod etc. Using a suitable size drill, drill the outer case of the bearing which should be spotted to accept the original locking grub screws. Apply a Threadlock to the screws first. Secure them in place, then re fit the propeller shaft, taking care not to damage the stern gland when sliding the shaft through it. Reconnect the gear box coupling to the shaft, but do not bolt it back onto the gearbox at this stage, fit the propeller and nut etc.

Now you can check the shaft to engine alignment. This can be done by moving the propeller shaft coupling up to the gearbox coupling flange without refitting the bolts. Alignment is near when you are able to put the two flange faces together easily without lifting it up, pushing it down or side to side. If you are unable to get the coupling faces together then the engine mounting feet bolts will need to be loosened to allow you to move the engine and get the coupling faces to connect easily.

The next stage of alignment is achieved using feeler gauges. With the two coupling faces pushed up to each other, use a 4 thou feeler and try to insert the feeler gauge between the two coupling faces going all the way round. If you can get the feeler gauge in at anyone particular point, then you move the engine until you can no longer get the feeler gauge in anywhere around the two coupling faces. Then carefully tighten the engine mounting feet and recheck using the feeler gauge again. If all is ok, you can refit and tighten the gearbox coupling bolts. Now you are done so give yourself a pat on the back and put your tool kit away.

If the job seems like to much for you to take on, please feel free to call MES Ltd for an estimate to complete the work for you, thus allowing yourself more free time to enjoy.
