Don't fall foul of an exploding PWC!


�In recent months there have been a number of videos cropping up on various social media channels showing PWCs exploding with very dramatic effects in what seem completely normal circumstances�, comments Rachel Andrews, RYA Chief Instructor, Power.

�I�m pleased to note that these concerning occurrences are few and far between and no incidents have been reported in the UK. However, to minimise the chance of an explosion owners should follow the recommendations in the owner�s manual and maintain the machine in accordance with the manufacturer�s instructions.�

The cause of these dramatic explosions is likely due to a build-up of fuel vapours that are ignited when the craft is started. By following a few simple steps you can minimise the chance of a dangerous and potentially life-threating situation.

Top tips to make sure you don�t become a victim of an exploding PWC:

  1. Use the correct (manufacturer-specified) fuel - the wrong fuel can damage the engine and fuel hoses
  2. Vent the engine when not in use to reduce the build-up of fuel vapours
  3. Follow procedures in owner�s manual regarding pre-start checks, for example, but not limited to:
    • Visually check the fuel system for leakage
    • Inspect hoses and fitments for signs of wear or damage
    • Check the exterior of the engine for damage
  4. Take special care when refuelling:
    • Do not overfill � heat from the engine or ambient heat can cause the fuel to expand and spill out of the tank
    • Wipe up fuel spills with a dry cloth
  5. Make sure the battery terminals and breather hose are undamaged and properly connected
  6. Ensure the electrolyte level in the battery is between the min and max level marks, as failure to ensure this could mean there isn�t sufficient power to start the engine and loss of power could leave the rider stranded.

�In short, think about the triggers and do everything you can to avoid them. Do not leave the PWC with a full tank in direct sunlight, do not smoke whilst riding or fuelling a PWC and follow the manufacturer�s recommendations for keeping your�Personal Watercraft�in great condition.�
