Inspection

Inspector Detail

Common issues

  • Hard starting from weak batteries, fuel system air or fouled injectors after long idle periods
  • Overheating from blocked seawater strainer, worn impeller or fouled heat exchanger
  • Fuel contamination or water in the fuel causing filter blockage or injector wear
  • Starter, charging or electrical connection faults from corrosion in the boat's confined space
  • Lubricating oil or fuel leaks at hoses, seals and joints
  • Failure to start in the cold from degraded fuel or poor battery condition

Inspection checklist

  • Start the engine on each starting system and confirm quick start and stable running
  • Check oil, coolant and fuel levels and inspect for leaks
  • Inspect the seawater system, strainer and impeller condition
  • Check batteries, charger, cables and starter connections
  • Verify fuel quality, filters and water separator
  • Test engine controls, stop device and instruments
  • Inspect exhaust and mountings for security and corrosion
  • Check that engine and gearbox are free to run ahead and astern, with the lifeboat afloat or prepared

Service intervals

Weekly engine start and run testweekly per SOLAS and the ship's SMS, with the boat in a safe condition
Oil and filter changeper the maker's schedule, commonly annually for rarely used engines
Fuel filter and water separator serviceannually or per the maker's schedule
Seawater impeller renewalper the maker's schedule, commonly annual
Battery condition checkmonthly and before each use

Typical intervals for this design class, not the manufacturer’s figures for your model. The manufacturer’s manual is binding.

Typical wear limits

Compression and starting performanceinvestigate when starting time increases noticeably - limits are maker-specific, confirm in the manual
Impeller wearrenew on the maker's schedule or when vanes show cracks or wear
Battery capacityrenew when it no longer holds the starting current needed

Ranges are typical for this design class. Always confirm against the manufacturer documentation for your serial number.

Critical spares

  • Fuel filters and water separator element
  • Lubricating oil filter
  • Seawater impeller and gaskets
  • Spare starter battery or charging parts
  • Drive belts
  • Injector or fuel line seals

Safety

  • Exhaust gas and fumes in an enclosed lifeboat require ventilation during test runs
  • Hot exhaust and engine surfaces cause burns, so guard and insulate them
  • Test runs with the boat in davits require safe securing arrangements
  • Fuel leaks create a fire risk in the boat, so check lines regularly

Class survey

Held under DNV MED certificate MEDB00002VM as a lifeboat and rescue boat propulsion engine. Surveyors typically witness a start and run test, check that the engine starts reliably and runs ahead and astern, and review weekly test records and battery condition.

Estimated lifetime: Low running hours in service, as lifeboat engines are mostly test-run; condition rather than hours usually governs overhaul, and the maker's guidance applies.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
