The regulator item #55 doesn’t seem to be available from marineengine but does appear elsewhere. But it’s expensive.

This one is available from marine engine for about $31: http://www.marineengine.com/newparts/part_details.php?pnum=OMC0580913. I don’t think it’s water cooled as the kit includes a flat mounting plate which may or may not be needed as a heat sink but can probably be easily ginned up. If the regulator simply shunts one stator lead to ground there is probably no substantial heat to be disposed of.

Maybe I’m confused; happens a lot….
