Re: 1995 Fast Strike 175 hp Johnson constant alarm
amvaneyk,
A 20-30 second horn would indicate a fuel restriction and a constant horn would indicate an overheating issue. To the best of my knowledge a constant horn will not go away without shutting down the engine and cooling to less than 207 degress.
A fuel restriction could be simple and just involve changing your external fuel filter, cleaning/replacing the internal filter and checking hoses/connections for leaks.
If the fuel restriction is not the issue, you should verify if the motor is actually overheating and go from there. You could also pull the thermostats and to see if they open by slowly heating in water on the stove. , you may be surprised by what ends up in the bottom of your pan after it opens. You could also back flush the motor with medium pressure through the thermostat openings. Then reinstall or replace the thermostats and flush through the rabbit ears with vinegar or another applicable product.
