Boat Services in North Wales

Boat services in North Wales, from engine  and boat systems maintenance to boat cleaning, is an important aspect for all boat owners. This article looks at boat detailing.

Part of protecting your boat in North Wales includes looking after the hull or inflatable tubes, the seats and interiors , the list goes on. This is important for the efficiency of the boat through the water. It is also both aesthetically pleasing and satisfying for the boat owner.

It is that time of the year when many boat owners are planning to take their boat out of the water. It is important to winterise the engine and boat at this time to help prevent problems incurring on re-launch in the Spring/Summer following the winter season.

The level of winterisation is dependent upon your boat/engine and should be done in line with the manufacturers recommendations.

The following are possible items that should be considered when taking your boat out of the water, but please note this is not an exhaustive list:-

  1. Fill your diesel fuel tank to the top. Why? This helps prevent condensation from building up inside the tank thus minimising the chance of diesel bug growth. Fuel additive maybe required to be added if there are suspect signs of the bug. Please see our blog on the dreaded fuel bug for further information.
  2. Check fuel filler cap seal – Why? This is to stop any water from entering the fuel tank to eliminate the risk of fuel bug growth.
  3. Change the engine oil with the correct oil specification for your engine. Why? This safeguards the engine from any corrosive acidic remnants of combustion remaining in there over the winter. Please note that the oil should be responsibly disposed.
  4. Change the oil filter – Why? Combustion products can build up in the filter which restricts the flow so it is a good idea to change a minimum of once a year and in line with manufacturer’s recommendations. This can be a messy job and again filters should be responsibly disposed of.
  5. Change and drain fuel pre-filter. Why? This can establish whether there is a problem with your fuel
  6. Check fresh water cooling level and top up and also check the condition/ratio of the anti-freeze. Why? Anti-freeze helps to guard the engine from the cold and, also acts as a corrosion inhibiter protecting the internal water ways within the engine
  7. Drain the cooling system for raw/fresh water cooled diesel engines, refill with anti-freeze solution and run up engine to circulate the solution around. Why? To guard against the cold and help protect internal waterways.
  8. Check the sea water pump impeller. Why? If impeller remains in one position for too long it can become deformed and less effective. Impeller blades can also brake off and cause issues within the engine and systems. Note impellers should be changed annually as a minimum.
  9. Clean bilges. Why? This helps spotting any faults easier and earlier.
  10. Disconnect batteries, check levels and charge up (check and charge every month to keep them in order). Batteries may need replacing if not keeping their charge.
  11. Prevent rust build up by removing air intake filter blocking entry with e.g. with an oily rag.
  12. Block off the exhaust (using tape, rags or bung) to help prevent moisture from getting into the engine
  13. Don’t forget about the interior upholstery and furnishings which may need to be removed. Ventilate areas by leaving cupboard doors ajar etc. Why? Prevent damp and mould build up

Boat Diesel Fuel Bug

Boat Diesel Fuel Bug

Some of our customers have recently come into our workshop having experienced issues with the dreaded boat diesel fuel bug. So, what is this, why is it on the increase, what problems can it cause, symptoms and how can you treat it.

Diesel fuel bug treatment

‘Diesel bug’ is a term used for the small microbes (bacteria), fungi and algae that can exist in boat fuel tanks between the fuel and the water. They live on the water that may be inside the fuel tank, have a short lifespan during which time they reproduce rapidly. However, it is their waste products and the dead microbes themselves that can cause the sludge at the bottom of your fuel tank.

It is the introduction of biodiesel (i.e. diesel made from plants and other biological matter) into the petrochemical diesel, which our fuel is now made from, that has caused an increase in the boat fuel bug. Biodiesel is seen as more environmentally friendly than the original petrochemical diesel, but it has a higher water content and also attracts more water when stored. As the water content of our fuel has increased so has the number of diesel fuel bugs as they survive off the water. Biodiesel fuel is also more prone to other particulate contamination e.g. rust, dirt, wax, sand etc. This increases the amount of sludge in the bottom of your tank.

The sludge that forms at the bottom of your boat fuel tank from the waste products, dead microbes and other particular contaminants can cause fuel lines to become blocked, blocked filters, blocked fuel injectors which may eventually lead to engine failure. The thin layer of the sludge can also cause corrosion which in turn can affect boat fuel pumps and injectors.

There are several symptoms that you may experience if you have a diesel bug issue such as

  • Filters becoming frequently blocked and needing to be changed often
  • Unexpected loss of power, engine stops or difficulty starting the engine
  • Sludgy sediments in your filters
  • Black smoke or awful smell from fuel
  • Fuel injectors becoming blocked requiring frequent cleaning
  • Increase in fuel or oil consumption
  • Cloudy fuel

Although difficult to remove there are still things that you can do.

  1. Prevention is better than cure. It is virtually impossible to prevent all water from entering the fuel tank (fuel tanks heat up during the day and cool down at night time which causes condensation water droplets in the fuel tank), but with good fuel management you can reduce the amount of water in your tank that these microbes live off. Good fuel management means storing fuel correctly (5-10OC), using before end date, removing old fuel and filling up with new diesel, the emptier the tank the more condensation build up will acquire and thus greater number of diesel bug.
  2. Using diesel bug treatments such as marine power blast (stocked at MES Ltd) either as a shock treatment or ongoing biocide
  3. Cleaning of your fuel tank
