Dont put crusader manifolds on. I would recommend putting on mercruiser ceramic coated ones or just some Oscos. I converted to oscos on my crusader 454s and never looked back.

You will probably save weight to over those big goofy crusader manifolds. Dont put on aluminum ones. I bought a 95 Sea Ray 270 Sundancer last season.

Dont have records to indicate when the manifolds risers were last replaced. Im paranoid about them failing and trashing my engine due to water ingestion. Marine Max seems hesitant to remove and inspect.
