new impeller and alarm is still going off!

[swellrider]

95 Johnson 50 HP. 3 clnd. The motor is new to me and I noticed that it wasn't peeing good so I changed the impeller. Put it back together and started it up and it was peeing great and the overheat buzzer started going off! I noticed that it also looked like a river coming out of the exhaust. Where the prop is. I'm stumped! What's wrong with it! Obviously I'm not a mechanic but I need some help!

Did you change out the thermostats? If they are not opening, then the motor will overheat quickly.

Thermostats, more than one? I pulled the one out on the top of the head, above the top spark plug. All kinds of corrosion in there. Diaphragm and springs look good but I noticed the nipple in the thermostat itself pops right out, is this supposed to happen or could this be the problem?

Was the old impeller torn apart? I just did some work on my motor, and I found a piece of the old impeller up under the thermostat cover. Is it possible there's a piece of the old impeller blocking up a water passage somewhere?

I would change it out anyway. Thermostats are cheap and easy to repair. Corrosion and thermostats are not a good combination.

The impeller was shot, but in one piece. I ordered the thermostat yesterday so it should be here by this weekend. The alarm I'm hearing is intermittent not a solid beep. I'm thinking it might be a vro buzzer??? Reason being, I ran it without the thermostat in. And it gave me the intermittent alarm again. And the motor was cool to the touch. What do you think??

Also, the vro is disconnected and unplugged
