Have your spark plugs changed AND carbs cleaned and adjusted.
Usually that can also be caused by a seized advance system ( plate under the flywheel, commanded to turn with the throttle linkage... )

50:1 But if your doing mostly low rpm cruising (trolling) then you could reduce that a bit to 75:1 to help reduce smoke. If you do mostly mid to higher rpm cruising, then 50:1 (1 pint to 6 gallons. )
Or 200mls in 20 liters if your Canadian.

Please only marine mechanics reply I have posted a question about my 90 hp force outboard the warning sound starts sounding while running full throttle after about 15 minutes of running full throttle I can...


Is this motor used in salt water?
That warning buzzer on your motor is really only tied to the temperature. In order to triage sensor or overheat condition, I'd recommend an infrared thermometer to get a reading on the engine as the buzzer is sounding. There is a product that is like a glue stick which can be pressed against the engine which melts at a very specific temperature... not sure if it's around anymore as the remote thermometers are pretty inexpensive now. Is there good water flow out of the ports below the cowling on the back?

Mercury outboard motor


Make sure the fuel tank is venting properly and the pump bulb is new and working properly! Other than than you have an ignition advance module that is not working as it should.
