Machinery Survey

Pre-purchase surveys include the main engines and generators. Identification and condition during the in water survey, operation and performance on trial.  We work with marine mechanics for analysis and testing of electronic fuel injected common rail diesels and petrol engines.  

Scope of our machinery survey report

  • Identification, cylinders and capacity
  • Make, model, serial numbers, hours
  • Kilowatt, metric horsepower / rpm rating
  • Morse controls and neutral safety switch
  • Tachometer, temp, volt, oil, boost pressures
  • Shaft drive mounts, glands, bearings, alignment
  • Seawater valves, strainer, grating and pump
  • Exhaust design, waterlift, muffler, hose/tube
  • Heat exchanger, coolant, thermostat, hoses
  • Steering, coupling alignment and propellers
  • Fire suppression, fuel and air vent shutoff
  • Natural or turbocharged, aftercooled
  • Specification and date of manufacture
  • Service history, including seawater service
  • Electronic control for cruise, troll, idle modes
  • Fuel tank, capacity, fillers, vents, filters, valves
  • Sail/stern/pod drive, mount, bearings, seals
  • Heat exchanger, oil, fuel and aftercoolers
  • Manifolds, risers, transom assemblies
  • Natural ventilation or AC/DC blowers
  • Auxiliary bilge, fire, hydraulic, compressors
  • Structural fire protection, commercial boats

Operation and performance on trial

  • Location, duration, weather, sea conditions
  • Oils and coolant verified prior to cold start
  • Fuel, oil, coolant, seawater or exhaust leaks
  • Hull, shafts, propeller and load condition.
  • Idle rpm, oil pressure and exhaust emission
  • WOT temp, oil and turbo boost pressure

Independent mechanics analysis and testing

  • Computer analysis of electronic fuel injected
  • common rail diesel and petrol engines
  • Cylinder compression test and oil analysis
  • Manometer and exhaust emission analysis
