Operating Your Outboard in Saltwater – Best Practices

Saltwater environments are tough on marine equipment, including outboard motors. However, with the proper care and maintenance, your BLADE Outboard motor can perform at its best, even in the harshest saltwater conditions. This article outlines the best practices for operating and maintaining your outboard motor in saltwater.

1. Rinse Your Outboard After Every Use

One of the most important steps in maintaining your outboard in saltwater is to thoroughly rinse the motor after each use. Saltwater can cause corrosion over time, so it’s essential to remove any salt deposits from the motor, especially after extended exposure.

• Procedure:
  • Flush your motor with fresh water using the designated flushing port. Run the engine at idle speed while flushing to ensure water circulates through the cooling system.
  • Rinse off the exterior of the motor, including the propeller, lower unit, and other exposed components.
  • Dry the motor and ensure all water drains out from any openings to prevent salt from settling inside.

2. Inspect and Clean the Propeller

The propeller is one of the most exposed parts of your outboard and is especially susceptible to saltwater buildup, barnacle growth, and corrosion.

• Procedure:
  • After each use, inspect the propeller for any debris, barnacles, or seaweed that could cause damage or reduce performance.
  • Clean the propeller using fresh water and a soft brush to remove any salt buildup or growth.
  • Periodically inspect the propeller for nicks, cracks, or signs of wear, as saltwater can exacerbate damage over time.

3. Use Corrosion-Resistant Materials

BLADE Outboards are designed to withstand saltwater, but using corrosion-resistant materials in key areas can help extend the life of your motor.

• Key Areas to Consider:
  • Anodes: Ensure that sacrificial anodes are installed and replace them when they become worn down. These anodes help protect metal parts from corrosion.
  • Seals and Gaskets: Regularly inspect and replace any worn seals and gaskets to prevent water from entering critical areas of the motor.

4. Monitor Battery and Electrical Systems

Saltwater can be particularly harsh on the electrical components of your outboard. Ensure that all wiring, connectors, and the battery are protected from corrosion.

• Battery Care:
  • Keep the battery clean and dry to prevent saltwater damage.
  • Make sure the battery terminals are free from corrosion. If corrosion is present, clean the terminals with a mixture of baking soda and water.
• Electrical Connectors:
  • Inspect electrical connections for signs of wear or corrosion.
  • Use dielectric grease on connectors to prevent saltwater from causing corrosion.

5. Store Your Outboard Properly

If you're storing your outboard for a period, make sure it’s stored correctly to prevent saltwater-related damage.

• Dry and Covered Storage: Store your outboard in a dry, covered space, preferably indoors, to protect it from the elements.
• Tilt the Motor: Tilt your motor up when storing it to prevent any remaining water from sitting in the lower unit or other parts of the motor.

6. Check for Leaks

Saltwater can infiltrate your motor through leaks. Regularly check your outboard for any signs of water intrusion, particularly around seals, joints, and the lower unit.

• Procedure:
  • Inspect the lower unit for any cracks or damage that could allow water to seep in.
  • Address any leaks immediately to prevent long-term damage.
