TOPIC: starter for 78 Mariner 48

I have an 78 mariner 48 hp. It is manual start. The motor was mfd. by Yamaha and there were 3 versions. a 48 a 55 and a 60 HP. the 48 is a manual start and the 55 and 60"s are electric start. i would like to locate a ring gear and starter motor from one of the electric start motors. For the purpose of converting my manual start to electric start. [img]http://www.fiberglassics.com./media/kunena/attachments/legacy/images/3nd3k93l1ZZZZZZZZZ97q2ea651c908ef14f1.jpg
