Prevent Overheating and Engine Codes: Don't Forget to Check Your Sea Strainer

One of the most common causes of engine warning codes and overheating issues in inboard boats is something that is often overlooked—the sea strainer.

The sea strainer plays an important role in your Malibu's cooling system by filtering out debris, weeds, grass, and other particles before they can enter the engine. When the strainer becomes clogged, water flow is restricted, which can cause the engine to run hotter than normal and trigger warning messages or fault codes on your display.

Signs Your Sea Strainer May Need Cleaning

If your Malibu begins displaying engine-related alerts, it's always a good idea to check the sea strainer first. Common symptoms include:

• Engine temperature running higher than normal
• Engine overheat warnings
• Check engine notifications
• Reduced water flow
• Loss of performance

Many times, a simple cleaning can solve the issue before it becomes a larger problem.

How Often Should You Check It?

We recommend checking your sea strainer regularly, especially if you're boating in lakes with heavy vegetation, floating debris, or shallow water. It only takes a few minutes and can save you from losing valuable time on the water.

As part of your routine maintenance, inspect the strainer:

• Before long weekends on the lake
• After operating in weedy areas
• Anytime you receive an engine-related warning
• During winterization and annual service
