400 HP @ 5,800 RPM. 409 cubic inch fully dressed marine engine. Replaces 454 HO, 502 HO, 496 Mag & 406 HO sterndrive engines including SeaCore and Horizon Bravo models.
Replacement for 21- to 31-foot single-engine boats and 28- to 38-foot twin-engine boats built before 2010 (prior to 2008 in California) and powered by 6.2L, 7.4L, 8.1L or 8.2L sterndrive and inboard engines.
