Have posted this before and have done a few things to fix this. Here goes. Have a 1986 Mercury XR2 150 outboard. When key is just switch on no buzzer sound. Water coming out of hole real good, smoking good on oil. Put a brand new oil alarm module on it still no buzz when key turned on. Only have about 1/3 of mine left to try and fix this. Any help would be appreciated.
