Maintaining Your Boat’s Propeller

Maintaining Your Boat’s Propeller

A banged-up or busted propeller on your boat can cause lots of problems, from draining your boat’s fuel tank to stranding you on the water. But prop problems are often avoidable so long as you are prepared and do routine maintenance. Here are a few tips on caring for your boat’s propeller.

  • Inspect your propeller regularly. Using a damaged prop can cause problems for your engine, propeller and stern gear. Get any nicks and dents fixed right away.
  • Regularly take off your prop so you can remove anything that may have gotten tangled around it like fishing line.
  • Clean your prop on a regular basis to make sure it doesn’t become corroded.
  • Keep track of your boat’s performance. A drop in speed or fuel efficiency, or any vibration, could be a sign of a propeller problem.
  • Put waterproof grease on your propeller shaft to keep it from getting corroded.
  • Regularly inspect your prop nut to make sure it doesn’t loosen and fall off.
  • Always carry a spare propeller onboard. It can help you get home if you have prop troubles on the water, and can allow you to keep boating if your regular prop is being repaired.
