How to Remove Salt Build up in Outboard Motor: 3 Methods

Saltwater is notorious for causing corrosion and salt build-up on various marine equipment, including outboard motors. Over time, this accumulation of salt can hinder the performance and efficiency of your motor, leading to potential mechanical issues. 

So, are you looking for how to remove salt build up in outboard motor?

Fortunately, there are several methods available to remove salt build-up and maintain the longevity of your outboard motor. In this article, we will explore different technique.  I’ll also provide you with a comprehensive guide on how to effectively remove salt deposits.

3 Methods for Removing Salt Build-Up in Outboard Motor

Now let’s move on to the main topic 

1. Freshwater Flushing

One of the simplest and most effective methods to remove salt build-up is freshwater flushing. After each use in saltwater, flush the outboard motor with freshwater to dislodge and remove the salt deposits. Follow these steps:

  • Attach a freshwater hose to the designated flushing port on the motor.
  • Start the engine and allow water to flow through for about 10-15 minutes.
  • Ensure the water flow is strong enough to flush out all salt residues from the cooling system.

2. Vinegar Solution

Vinegar is a natural acid that can help dissolve salt build-up on metal surfaces. To use this method:

  • Mix equal parts of vinegar and water in a bucket.
  • Dip a soft cloth or sponge into the solution and gently scrub the affected areas of the outboard motor.
  • Rinse thoroughly with freshwater after scrubbing.

3. Salt-Removing Products

Salt Off: Salt Off is a commercially available salt-removing solution specifically designed for marine equipment. It effectively breaks down and removes salt build-up. Follow the instructions provided on the product for optimal results.

Salt Away: Similar to Salt Off, Salt Away is a specialized product that helps remove salt deposits. It typically comes in a concentrated form that needs to be mixed with water. Follow the manufacturer’s instructions to ensure proper usage.

So, Which One is the Best Method to Remove Salt Build up in Outboard Motor?

In terms of overall effectiveness and convenience, the best method for removing salt build-up in an outboard motor is freshwater flushing. Here’s why:

Effectiveness: Freshwater flushing allows for a thorough and direct removal of salt deposits from the motor’s cooling system. By flushing the motor with freshwater, you can dislodge and flush out the salt effectively, preventing it from causing corrosion or hindering the motor’s performance. It is a proactive approach to maintenance.

Convenience: Freshwater flushing is a straightforward process that can be done immediately after each use in saltwater. It requires minimal additional materials, as all you need is a freshwater hose and access to a water source. It doesn’t involve purchasing specialized products or mixing solutions, making it convenient and cost-effective.

Accessibility: Freshwater is widely accessible, whether through marina facilities or by using portable freshwater tanks or containers. This accessibility allows boaters to perform freshwater flushing without relying on specific products or solutions.

While vinegar solutions and salt-removing products like Salt Off and Salt Away can be effective in certain situations, they may require additional steps, such as manual scrubbing or the purchase of specialized products. These methods can be useful for occasional deep cleaning or for tackling more stubborn salt deposits. However, for regular maintenance and preventing salt build-up, freshwater flushing is the most practical and effective choice.
