Have 1990 Force 150. Just replaced impeller because of high pitched buzzing, hot engine. Since replacement engine is running fine. When I switch on the key a low audible buzz begins and never ends. I read one suggestion about mix ratio but I mix according to manual.
HELP
 
The ONLY thing the 1990 150 buzzer was for was
to tell you the motors overheating.

Now if the buzzer is still sounding off, the sending
unit on the head might be shorting???

Unhook the orange lead on the buss bar where all
the wires connect.
That should disconnect the sensor.
That should stop the buzz.

You sure the buzz is coming from the buzzer? Touch it?

That didn't help? Maybe the bilge pump is on?
