The gaskets on any boat intake manifold may eventually wear out, especially in extreme marine conditions. Marine Parts Source has a large collection of Crusader intake manifold gaskets to replace broken seals before they lead to bigger problems. Engine misfires, a bad air-fuel mix, a loss of power and overheating are all signs of potential gasket issues. Contact us for assistance diagnosing your issue and confirming if you need a new manifold gasket.

We stock OEM intake gaskets for all leading Crusader boat engine models. You can get an L29 454 intake manifold gasket, a Gen V 502 square port gasket set or intake gasket sets for GM 305 and 350 small-block engines. Select a kit to verify compatibility and see which stock part number it replaces. Gaskets may be sold as singles or in a set, though we recommend replacing both at once. Get the seals you need with fast shipping from warehouses across the U.S. Call us toll-free at 866-388-0390 or use our contact form.
