Learn how filtration, water separation, pressure indicators and bleeding affect Cummins and Yanmar common-rail yacht engines.
Learn how to identify water and microbial fuel contamination, interpret filter symptoms, test tanks and decide whether polishing is appropriate.
Learn what white, blue and black yacht exhaust smoke can indicate, what is normal during cold starting, and when to reduce load or call an engineer.
Learn how to assess smoke, power loss, intake restriction and air-cooler fouling, and when a marine diesel needs professional diagnosis.
How to inspect exhaust water flow, mixing elbows, hoses and waterlocks, and respond safely to leaks or possible engine water ingress.
Learn how to take comparable yacht engine oil samples, read wear metals, contamination and viscosity results, and recognise worsening trends.
Work through seawater discharge, strainers, coolant level, thermostats, belts and heat exchangers without opening a hot cooling system.
Learn how running hours and calendar limits control yacht engine servicing, with model-specific examples and practical record checks.
Learn how to separate no-crank and no-start faults, check batteries, interlocks and fuel, and avoid wet-exhaust water ingress.
Learn how to manage calendar servicing, standing fuel, pre-start checks and recommissioning when a yacht engine sits for months.
A captain's order of work when an engine alarm sounds: safety first, take the load off, record the fault code, then the common alarms and when to call.
