'89 yamaha 200 2 stroke alarms??

[seaox20]

I have a '89 yamaha 200 2 stroke outboard and when i get on plane or get to a certain rpm the alarm on the ignition switch goes off and then bogs to motor down so i dont blow the motor. The oil injection is full, the motor pisses, and i can see the motor blowin 2-cycle smoke out. it appears to be gettin oil and not overheating. Do i have a bad sensor on the alarm? is it not getting enough oil or is it overheating? any advice would be great...thanks for your time seaox20 out

You will have to test the different switches to see which one is giving the alarm.
We do not have any crystal balls that work on outboard motors. Yet!
