Winterising Boats

Winterising Boats

With boats starting to be laid up for the winter it is time to consider moth balling your boat for winter.Ordovic Boat Brokerage has some good advice on winterising boats for winter.
1. Firstly, it is good practice to fill your fuel tank to the brim to prevent any condensation and minimise the prospect of diesel bug growth.Whilst filling up your fuel tank take time to add some fuel treatment to kill off or prevent diesel bug.
2. Change the engine oil and replace the oil filter. It is best to do this as you lay up, otherwise leaving old oil which may be contaminated with the acidic remnants of combustion inside the engine block could shorten the engine's life.A neglected oil system can cause expensive repair bills.Replace the fuel filters.A plastic bottle cut in half is ideal for this as you can drain the fuel and in some cases catch the filter in the bottle and because it's clear you can examine the condition of the fuel. The screwtop end of the bottle can be used as a funnel to pour into a container for disposal. Once you have refitted the filters you will need to bleed the system.Some fuel filters may need to be filled with fuel from a can.If severe diesel bug is present in the tank it may need to be drained or removed to be cleaned and the fuel system thoroughly flushed through.
3. If your gearbox oil looks cloudy or milky change this before winter too.
4. Most Diesel engines use either raw water cooling or freshwater coolingand these require attention as well.Before lifting out, drain the cooling system by disconnecting the hose from the circulating pump or use the tap or plug if one is fitted and refill with a string solution of antifreeze.Run up the engine to circulate the solution.Just draining the system is unlikely to remove all of the water inside which could freeze and cause damage over winter.
5. When ashore remove the air intake filter and stuff the intake with a oily rag to prevent rust building up inside.Also, you may wish to squirt a little oil in to the intake and turn the engine over manually to spread it over the cylinder walls.
6.Ensure batteries are kept dry and warm if possible and fully charged or topped up every month or so.If they are not maintained for long periods there is the possibility that they may need replacing.If you cannot remove the batteries charge them regularly, disconnect them from the system and clean and grease the terminals.
7. Remove the impeller.If the impeller remains in one position for too long it may become deformed, brittle and less effective and fail. You should always change your impeller annually.Using an old one as a spare may be acceptable in an absolute emergency but best practice would be to keep new ones as spares.
7. Slacken off or remove all the belts and protect the drive wheels from rust.Rust can very readily wear a belt out in no time.
8. It is also advised to block off the exhaust and this can easily be done with tape, rags or a wooden bung.This helps prevent moisture from getting into the engine.
9.When laying up ashore make sure that the bow is angled upwards slightly to ensure water will run off the vessel.
10.Any covers left on the vessel should keep water out but still allow areas to breathe to prevent condensation that can lead to dry rot, mould and corrosion, particularly if the boat is to be left for more than one season.
11.Remove all linen, clothing curtains, blankets and upholstery for safe storage.
12.Leave cupboards and drawers open, prop up any upholstery if left onboard and try to ventilate every little area where possible.
13.If you are leaving electronics on the vessel make sure they have tight fitting covers and maybe spray behind the electronics with a good water repellant silicone.Taking these off the boat is a good idea you can to discourage theft.
14.Always refer to the manufacturers manuals and recommendations.
