The material quality of the distributor cap is crucial as it determines its durability and performance. Look for caps made from high-quality materials such as brass or aluminum as they are more resistant to corrosion and can withstand high temperatures and electrical currents.

4. Brand Reputation:

I always prefer to buy from reputable brands that have been in the market for a long time and have a good track record of producing quality products specifically designed for marine engines like Mercruiser.

5. Warranty:

A good warranty ensures that you are covered in case of any defects or malfunctions with your distributor cap within a specified period after purchase.

6. Price:

The price range for distributor caps can vary depending on brand, material, and other factors mentioned above. While it may be tempting to opt for cheaper options, remember that quality should be your top priority when it comes to essential components like this.

7. Reviews and Recommendations:

I always like to read reviews from other customers who have already used the product before making my purchase decision. This helps me get an idea about its performance, reliability, and any potential issues I should be aware of.
