This Sierra starter, part number 18-5908, is a top-mount, rear-entry starter for GM and Ford engines. It replaces Mercruiser 50-76965A3 and 50-808011A1, plus OMC 981288, 982195, 984982 and 986007. Crusader 42091 and Pleasurecraft RA122009 are also listed. The rotation direction is not consistent in the details, so confirm it against your old starter before fitting.
Our take
The 18-5908 is a top-mount, rear-entry starter, and the details give both CW and CCW for rotation, so rotation is the first thing to confirm. The replaced numbers, 50-76965A3 for Mercruiser and 981288 for OMC, give a clean way to match it.
