Winter is not suitable for enjoying the yacht life, many people will put the yacht away and continue fishing when the weather is warmer
TRODAT will show you some common maintenance tips for your fishing boats.
Main engine maintenance
1. Routine maintenance
Winter maintenance of yachts first need to go ashore once a year for routine maintenance. For example: oil, filter, zinc block, gear oil and some other routine maintenance replacement.
2. Check the water-containing system
When the temperature is close to 0℃, in order to avoid freezing, the blue plug on the main engine will be unscrewed to empty the water inside the cooling pipe and empty the water from the water pump assembly on the main engine. Nevertheless, whenever the outside temperature drops below 0°C, the water inside the pipes (fresh or sea water) may still freeze and cause the pipes to rupture. Therefore, it is essential to check all water-containing systems and equipment, including seawater systems (engine cooling systems, generator cooling systems, etc.) and freshwater systems (wipers, fresh water pumps, etc.) diligently.
3. Generator maintenance
The generator should also be serviced as routinely as the main machine maintenance. Close the subsea valve, suck the water out of the filter cup, check the oil and fuel filters, and replace them if necessary.
Follow the use and maintenance guidelines provided by the engine and generator manufacturer.
The valve of the generator, suck out the excess part of water in the filter.
4. Air conditioning maintenance and repair
After the air conditioner is winterized, close the subsea valve of the air conditioning cooling system and suck dry the water in the filter cup and empty the water in the pump, and open the subsea valve before using the air conditioner in the coming year.
5. Fresh water system maintenance
Clean the fresh water tank with disinfectant and drain the fresh water. Drain the water in the faucet and shower pipe, leave the faucet in normal open condition, clean and check if the float is working properly.
