Parts for vintage Yamahas. ECU $50, Coil $20, Rebuilt starter and relay, $150. They were on a 1987 Yamaha Excel III, but can be used on other older Yamaha sleds. All checked out good by a Yamaha dealer and in great condition. Buy them all for a better price! Parts are located in Andover, but I can meet you near Bethel, Auburn or Portland areas also, if needed.
