92 johnson fast strike 150 overheating

[briancrowley]

constant buzzer turns on at idle. I replaced water pump (kit) still buzzing. Replaced thermostats, still buzzing. replaced temperature assembly switch. that fixed the problem for a week or so. buzzer came back on (between that time my regulator rectifier went out and was replaced). so I am assuming I need a new temperature switch? water is peeing out the back not sure of psi. i can't imagine boat is overheating at idol with water peeing. please help!

Have the head temps been checked with a temp gun? Correct water pump part number been installed? Have you removed the thermostats and the caps and run the motor to make sure there is good flow coming out of them?

no temps, correct water pump, good flow. I dont know if something is wrong with the new sensor. could it be the vro went bad and not giving oil to the motor causing it to overheat? and if so how would i check that?

Disconnect the oil tank wiring and see if the horn stops
