Checklist: safe test drive of motor

It must be in place before the engine starts

Starting an engine after a repair is one of those moments where things can go wrong — overheating, exhaust gas, a moving propeller or leaks. A fixed checklist before, during and after the test run keeps both you and the engine safe.

§Before you start

  • 01Secure cooling: either the boat in the water or supply the engine with water via cooling muff
  • 02Check oil and coolant level and any leaks
  • 03Provide extraction or fresh air — exhaust is life-threatening indoors
  • 04Keep distance from propeller and rotating parts, and remove loose clothing and tools

§During the test drive.

  • 01Keep an eye on temperature, oil pressure and charge on the instruments
  • 02Listen for unusual sounds and feel for vibrations
  • 03Check that coolant flows out as it should
  • 04Stop immediately at alarm, smoke or unusual odour

§After the test drive

  • 01Check for leaks while engine is still warm
  • 02Check cargo and tie-down points for damage before next loading.
  • 03Note the result on the work order
