How to Maintain an Outboard

Maintenance is essential to ensure safe and reliable operation of your outboard motor. Failure to properly maintain your motor can result in shorter engine life or possible damage to its components. There are simple steps you can take in order to properly maintain your outboard motor.

After Each Use

• 1

  Flush the motor's cooling system if it was used in saltwater or water containing any pollutants.

• 2

  Clean off any salt deposits and flush the exhaust outlet of the propeller and gear case using clean, fresh water.

• 3

  Inspect propeller blades for damage such as chips, dents and bent blades. Any damage to the propeller can cause vibrations and damage to the motor and will reduce efficiency.
