There are correct types of hose for marine plumbing, sewerage, exhaust, cooling and gas and all hoses should be checked regularly for wear and deterioration. Hose clips should also be checked for corrosion. Nowhere is this more important than with the gas system, so it is important to check on the condition of the piping and clips. If there are any signs of corrosion, cracking or leaking in the pipes or flexible hose, then these should be replaced as a top priority.

gas system maintenance

Gas bottles should be well secured in their lockers and gas drains left unobstructed. Don’t be tempted to use the gas locker for extra stowage, as this could result in a blocked gas drain. The gas stove should have no signs of corrosion and burners need to be in full working order, including their safety cut outs.

Gas regulator

Bottled gas is stored in gas bottle under very high pressure. A gas regulator is required to reduce the pressure before it enters the gas system. The regulator also incorporates an on/off control.

A regulator has a small air hole which is needed in order for a diaphragm inside it to work. If this becomes blocked then the gas will not flow properly, so this needs to be checked. If the regulator is corroded or has passed its expiry date it should be replaced.

gas system maintenance

Note: Gas systems should be installed by qualified engineers and in some countries this is compulsory. It is important for a boat owner to understand their boat’s gas system and to be able to troubleshoot any potential problems. However, if an owner chooses to do their own maintenance work, then hiring an engineer to do a final check of the system is advised to ensure their boat is safe.

Common marine electrical problems

Most problems with marine electrical systems arise from four possible sources, a lack of maintenance, a poor standard of initial installation, insufficient battery capacity, or ineffective charging systems.
Water ingress is a frequent issue – salt water can corrode contacts very quickly. If connections are not scrupulously clean – or are loose – resistance will be increased, resulting in progressively reduced power.

Boat electrics

All boat owners should have a basic knowledge of electrics, both to avoid encountering electrical problems at sea and to stand a chance of solving them should they occur.
