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.  Because this is a completely new engine and not a major repair assembly, the old engine being replaced is to be returned per EPA rule 1068.240.
