My buddys 1995 Yamaha Outboard 3cyl 90hp wont start and we cant figure out why.  When we turn the key we get nothing.  The killswitch is attached and the battery is working because all of the lights turn on.  The throttle is in nuetral and everything in sight seems to be hooke up correctly.  Looking at the motor we found an "emergency switch" that when pressed down the motor will start.  The switch looks a lot like the killswitch on the column but is laying looses only attached by a couple wires. When we use this button and the motor is running, the engine still turns off when the killswitch is released.  ANy ideas of what could be wrong and ways to fix them?

The best advice I can give is to get a manual for the motor. You might be able to rig a toggle switch to it and get it to run that way. If you are not worried about your boat being "stock". sounds like the switch is backwards of a kill switch.

There will be a fuse somwhere under the cover,chek to make shure that it is ok.
