This is a used Yamaha 67H-85540-01-00 CDI unit. It has been tested on a running 2003 Yamaha 200 HP engine and worked perfectly. It shows to work on several Yamaha 150 and 200 hp engines from 2001 to 2005. Hired hand broke one of the connectors. We tested with it like it is and worked fine. Connector from your old unit can be put on this one. We shipped this unit to a customer and somehow, between here and there, the plastic around where the main plug was cracked out. We tested it when we got it back and it works great. I'd run a big tie wrap to ensure that the main plug doesn't come out. I dropped the price from $699 to $599 due to the piece around the main plug being chipped out. And I do guarantee it to be in good working order. Email me your engine info if unsure of fit.
