1997 force 120 hp outboard buzzer after 5 min

Hey guys any ideas? I have a 97 force 120 and after about 5 min a slight buzzer sound is coming from the control areas. I have a good strong flow from the pis..r hole and the water is cool. any ideas faulty sensor, buzzer, waterpump,? doesnt seem to be o/heating and the fuel pump is not a vro i have to mix the gas. any ideas getting ready for a tourney thanks

Only warning those motors have is overheat. Weak impeller, thermostat, water flow restriction or it could be a faulty warning horn or even a partially blown head gasket.......OPTI

Take your temperature sensor out and clean it.

is it on a procraft bass 170? if so pm me...

Sounds like a thermostat could have trash in it or may be stuck open. Always a good idea to replace the water pump impeller every other year. I do some bass diehards every year.

could you tell me where the temp sensor is. I am trying to find a diagram or manual on line but no luck
