Inboard Engine Distributor Caps

The distributor cap on an inboard engine is subject to a lot of stress and typically should be replaced every 4-5 years — or more often if you’re a frequent boater. Signs of wear such as engine misfiring, shaking, squealing and difficulty starting are also indicators you need a new cap. Marine Parts Source has a large collection of inboard distributor caps, including aftermarket and OEM components to ensure the best performance. Trust brands such as Sierra, Crusader and our own Powerline brand for the highest-quality distributor parts.

We have caps for dozens of engine and distributor models. Whether you have an older four-cylinder inboard engine or a new GM big block, you can find the right distributor cap at a great price. Select a product to learn more about it like what engines it’s compatible with and what part number(s) it replaces. Our staff has extensive knowledge of the parts we sell and can assist you — call 866-388-0390 or email support@marinepartssource.com.
