On the key switch get a ground and touch the white wire. Does the engine quit?
Customer: replied 1 year ago.
No but not sure I am getting a good ground.
Customer: replied 1 year ago.
I unplugged the only white wire I see which runs from the kill switch
Expert:  Tan replied 1 year ago.
Get a ground off the boat fuse panel and touch the white wire on the key switch. Or you can run a ground directly from the battery. Ground the white wire from a good ground.

Still does not shut down.
Expert:  Tan replied 1 year ago.
Ok either the white wire is broken in the harness or the CDI unit is shorted internally. Disconnect the harness from the CDI unit and with an ohm meter do a continuity test of the white wire. Do you have continuity?
Customer: replied 1 year ago.
Mine only has 8 pins.. what is the CDI unit?
Expert:  Tan replied 1 year ago.

Expert:  Tan replied 1 year ago.
Ok here is the CDI # ***** unit locate the white wire and ground it does the engine shut off? http://www.boats.net/parts/search/Yamaha/Outboard/2000/C115TLRY/ELECTRICAL%201/parts.html
Customer: replied 1 year ago.
There is no continuity between the white pin on the cdi harness and white white in main harness..
Expert:  Tan replied 1 year ago.
Ok can you ground the white wire at the CDI unit? This will verify the harness as the issue.
Customer: replied 1 year ago.
