how can propeller strike accidents be avoided?

Propeller strike accidents are avoided by keeping people clear of the propeller area, shutting the engine off whenever anyone is boarding, disembarking, swimming, or being picked up from the water, and maintaining a constant lookout for swimmers, divers, and fallen skiers.

Core safety habits

  • Never start the engine while anyone is in the water near the boat.
  • Make sure the engine is in neutral before starting, and never start in gear.
  • Turn off the engine before passengers board or leave the boat.
  • Do not allow anyone to sit on the transom, gunwale, bow, or seat back.
  • Keep a responsible adult or designated observer watching children, swimmers, and skiers.

While operating

  • Slow down in congested areas, anchorages, and near swimming zones.
  • Stay well clear of marked swim areas and diver-down flags.
  • Use a kill switch or engine cut-off lanyard so the engine stops if the operator is thrown from the controls.
  • Avoid alcohol or drugs while operating the boat.

Picking someone up

  • Approach a person in the water slowly and from a direction that keeps them in sight.
  • Take the engine out of gear and shut it off before reaching them.
  • Do not reverse toward a person in the water.

Extra precautions

  • Post propeller warning labels and teach passengers where the danger zone is.
  • Consider propeller guards or other safety devices if they fit your boat and use case.
  • Do a head count before starting the motor, especially with groups or children on board.

A simple rule helps: if anyone could fall, swim, or step near the stern, the engine should be off.
