1998 Yamaha 200 Oil alarm

[jahinton]

Thanks for looking and any help would be greatly appreciated.

I have a 98 200hp Yamaha 2 stroke that I bought used. The guy before me had eliminated the oil injection system, yes I know bad idea but it is done. I am getting a periodic alarm that seems to also send the engine into a reduced power mode, the oil light comes on that is on the tach, so I assume it is an oil sensor of some type. What wires do I need to check to make sure they are grounded to eliminate any oil alarms and the reduced power mode? Thanks again for any help.

Have both oil tanks and sensors been removed or still in the boat? Also is there an oil pump still mounted or block off plate? If there’s still an oil pump on the motor make sure the shaft has been removed.
