Marine gaskets are highly recommended over standard automotive gaskets for top efficiency, safety and performance!

Minor wear, warping and corrosion are simple facts on marine engine surfaces and the marine gaskets are designed to combat this.

You can rely on marine gaskets to stand up in the demanding environment of freshwater or saltwater use.
