How to change oil in a boat?

Equipment needed

  • An oil filter wrench
  • A wrench for your crankcase drain plug and a pan
  • A dipstick-tube oil drain pump and bucket big enough to hold all the oil
  • Paper towels
  • New oil filter(s)
  • A supply of fresh oil as recommended by your engine manufacturer

How to change the oil, step-by-step

  • Run the engine(s) until warmed to at least 130 degrees
  • Drain the oil using the pump, or into the pan
  • Replace the plug or close the valve
  • Loosen the oil filter on the engine until it can be turned by hand
  • Put a Zip Lock Baggie around the filter, and unscrew the rest of the way
  • Use a paper towel to catch drips from the filter's mounting
  • Seal the zip lock baggie keeping the filter upright
  • Put it into the new filter's box
  • Using your finger, wet the O-ring above the new filter with fresh, clean oil
  • Screw on the new filter until just finger-tip tight
  • Follow the manufacturer's recommendation as to tightening with the wrench
  • Re-fill the crankcase with new oil (see your engine handbook)
  • Be sure to add a quart for the filter
  • Wipe up any drips
  • Start the engine and let it run a few minutes
  • Check to be sure oil pressure comes up and there are no oil leaks around the filter or drain plugs
  • Dispose of the oil properly at an approved disposal facility
