Fuel & Lubrication
Routine maintenance of the fuel and lubrication systems is essential to prevent common issues like saltwater contamination and corrosion. Key tasks include draining the fuel tank, cleaning out any sediment, and replacing fuel filters. Modern diesel engines require additives due to emission regulations. Always use the correct marine diesel fuel by consulting a professional and reading the manuals. Issues such as clogged filters or a malfunctioning fuel pump can lead to fuel starvation. A malfunctioning fuel pump that sends air through the system can cause rapid wear on bearings and improper fuel pressure for injectors. Ensure the right engine oil is used according to the manufacturer’s guidelines.

Coolant
Marine coolant is vital for smooth yacht operations. Just like oil, it is important to follow the manufacturer’s recommendations. Marine coolant helps prevent corrosion, increases the boiling point, neutralizes engine by-products, and stabilizes engine temperature. It is advisable to check the coolant level before each trip.

Exhaust and Air Intake
Observing the exhaust smoke when starting the yacht is important. While a small amount of black smoke is normal, larger amounts may indicate issues that need investigation. Regularly inspect air filters as they significantly affect engine performance and longevity.

Cylinder Heads and Blocks
For most yacht owners without diesel system expertise, a visual inspection is sufficient. Ensure the head bolts and valve timing are properly torqued. Owners who require pristine engine conditions may clean the area using degreaser products, following the instructions carefully. It’s typically best to leave any in-depth engine work to professionals.

Electrical Systems
While electrical work is usually handled by professionals, owners can perform basic checks such as ensuring batteries are charged, examining engine wire connections for any loose or corroded parts, and replacing bulbs for interior and navigation lights.

Transmissions
The transmission is a critical, yet often underappreciated, component of a yacht. Regular fluid checks and visual inspections are necessary. If issues arise, a professional is typically needed. Transmission failures can be deceptive and lead to being stranded. Regularly cleaning the gearbox from saltwater and excess oil is crucial, and conducting oil sample analysis during oil changes can help detect potential issues early.

Yacht Maintenance Costs
A general guideline in yachting is that annual operating costs, including maintenance, should account for approximately 10% of the yacht’s purchase price. Newer yachts may fall below this estimate due to fewer breakdowns and coverage under warranty. However, if purchasing a used yacht, maintenance and repairs could be higher. Always inquire with your broker or salesperson about the expected maintenance costs for a particular yacht.
