May. 26 2025 Maintenance By LMC Marine Center

Proper maintenance of your outboard motor ensures optimal performance and longevity. Whether you're a seasoned boater or a beginner, keeping your motor clean is essential. At LMC Marine Center in Houston, TX, we understand the importance of a reliable outboard motor. Let’s dive into the key steps for cleaning without harming its components.

Gather Necessary Cleaning Supplies

Before starting, make sure you have all the necessary supplies on hand. This will typically include buckets, mild detergent or soap, a soft-bristle brush, and fresh water. It's also useful to have some clean rags or towels available for drying.

Begin with the Exterior

Start by rinsing off any loose dirt or debris from the motor's exterior using fresh water. This helps prevent scratches during the cleaning process. Apply a mixture of water and mild detergent gently with a soft-bristle brush to wash away grime without damaging surfaces.

Pay Attention to Engine Components

After cleaning the exterior, focus on engine components under the cowling. Carefully remove any debris or buildup around these parts to prevent future mechanical issues. Be sure not to use forceful water jets that may infiltrate electrical areas.

Inspect Cooling Water Intake

Check and clean your cooling water intake ports as they can become obstructed with sand or weeds over time. Use light pressure with a hose to rinse these areas thoroughly.

Dry Your Outboard Motor Thoroughly

Proper drying is crucial to avoid corrosion and protect against rust. Wipe down all areas with absorbent towels, ensuring no moisture remains trapped in nooks or crevices.
