Impellers for outboard engines

Outboard motor impellers are a critical component of your engine's cooling system. A worn or damaged impeller can cause overheating, leading to serious and costly engine damage. That's why choosing high-quality impellers and replacing them regularly is essential.

At Nautica Basile, you'll find many replacement impellers for outboard motors, compatible with leading brands like Johnson, Suzuki, and Mercury. We only offer products from official suppliers, such as Cef Marine and Osculati, guaranteeing maximum reliability and performance for your boat motors.

How to Choose the Right Impeller?

Carefully check your engine model and compare it with the impeller specifications. Verify the original equipment manufacturer (OEM) part number to ensure compatibility. Pay attention to the dimensions (A mm, B mm) and the number of blades.

Common Problems and Solutions

* Wear and Tear: Impellers are subject to wear and tear due to friction with water and sand. Regularly inspect the condition of the impeller and replace it if you see any signs of damage.
* Fouling: Fouling can reduce the efficiency of the impeller. Clean the impeller regularly with marine-specific cleaning products.
* Overheating: If your engine is overheating, immediately check the condition of the impeller. It may need to be replaced.

The Basile Workshop Tip

Replacing the impeller is a routine maintenance task that you can perform yourself. However, if you don't feel confident, consult an experienced mechanic. Remember to lubricate the impeller with marine grease before installation to ensure proper function in your outboard motors.

Frequently Asked Questions

Will this fit my Suzuki DF40?

Check the original part number printed on your old impeller and compare it with the compatible part numbers listed in the product sheet. Alternatively, measure the inner diameter (A mm) and outer diameter (B mm) of the impeller and compare them with the dimensions indicated.

How often should I replace the impeller?

The impeller should be replaced at least once a year or every 100 hours of operation, even if it appears to be in good condition. If used intensively or in particularly dirty water, it is advisable to replace it more frequently.

Can I use a compatible impeller instead of the original?

Compatible impellers from reliable brands such as Cef Marine or Osculati offer performance equivalent to the originals, at a lower cost. Always ensure that the compatible impeller meets the technical specifications of your engine (original part number, dimensions, number of blades).

What happens if the impeller breaks while sailing?

Impeller failure causes interruption of the cooling flow and engine overheating. Immediately reduce speed and turn off the engine to avoid serious damage. Call for assistance if necessary.
