Keep your 4-cylinder marine engine running at peak performance with this complete Delco tune-up kit. Featuring essential ignition components—cap, rotor, points, and condenser—it's engineered specifically for conventional Delco distributors. A straightforward maintenance solution that restores reliable starting and smooth operation, helping you avoid costly downtime on the water.
Maintaining a marine engine requires high-quality components for long-term reliability. Furthermore, the Tune Up Kit Delco 4 Cylinder | Sierra 18-5268 provides everything needed for a professional ignition service. This comprehensive package ensures your engine starts quickly and runs smoothly on the water. Therefore, investing in this kit is a smart move for any boat owner.
Sierra is a leader in marine engine parts because they prioritize durability and precision. Consequently, this kit is specifically designed to meet or exceed original equipment standards. Since marine environments are harsh, these components feature corrosion-resistant materials. Additionally, the kit offers a perfect fit for Delco in-line 4-cylinder engines. You can trust that these parts will handle high-performance demands easily.
This all-in-one solution saves you time by bundling essential ignition parts together. Specifically, the package includes a premium distributor cap and a high-conductivity rotor. Moreover, it contains a precise contact set and a heavy-duty condenser. Because these parts work in harmony, your ignition system will achieve optimal timing. As a result, you will notice improved fuel efficiency and better throttle response.
Finding the right part is crucial for avoiding mechanical issues during your trip. Fortunately, the Sierra 18-5268 is the ideal match for Delco single-point ignition systems. It serves as a direct replacement for many common marine engine brands. For example, it is compatible with MerCruiser, OMC, and Chris-Craft applications. Always verify your specific model number to ensure a seamless installation process.
Installing this tune-up kit is a straightforward task for most DIY boaters. First, ensure your engine is off and the battery is disconnected. Next, replace the old distributor cap and rotor with the new Sierra components. Then, swap out the points and condenser to refresh the electrical signal. Finally, double-check your connections before starting the engine for a test run. This routine maintenance prevents unexpected breakdowns and extends your engine's life.
Keeping your boat in peak condition requires attention to detail and quality parts. Ultimately, the Tune Up Kit Delco 4 Cylinder | Sierra 18-5268 is the best choice for reliability. By choosing Sierra, you are choosing a brand with over 50 years of marine expertise. So, do not wait for a failure to happen before upgrading your ignition system. Order your kit today and enjoy a worry-free season on the open water.

Would have been 5 stars but, I did not receive a promotional sticker with my $2000 drive unit. Just kidding, everything was great!
Great company to work with!
Ordered a Piranha Propellers Complete A-Series 4 Blade Propeller from Macomb Marine Parts and even though we’re international, it arrived in just over a week — fast and reliable service. The propeller itself is a real lifesaver. We had the same model before, and after hitting a rock that damaged two blades, we were able to swap them right on the water and make it back to the marina without issue — something you simply can’t do with a regular aluminum prop. For peace of mind we decided to buy a complete new set (hub and blades) since an impact like that could cause hidden damage, but the system really proved its worth.

Excellent part.
I couldn’t find a Piranha propeller dealer near me in Canada but found Macomb Marine Parts who could deliver to me. The order process was smooth and I was even contacted via email for clarification regarding blade shape and they were very helpful in choosing the best shape for my purposes.
I can’t comment on the prop’s performance yet as we haven’t had the boat in the water yet.
Perfect replacement. thank you
