Warning buzzer

[billynjuls]

I hope someone can help. I have a 1992 Evinrude 150 Intruder. This morning as soon as I started up my motor a warning beep came on. At first it was a beep and a pause, beep and a pause. The tell tale has water coming out. I mix my gas and oil. After a while the beep stayed on constantly. Sometimes at idle it wouldn't beep, but as soon as I gave it a little throttle it would beep constantly and die. Every time I would go WOT it would stay on constantly before it would bog down and die again. There was quite a bit of white smoke coming out and the engine was shuttering at times. Every once in a while it would take off great for a while and then bog down like it wasn't getting fuel. I would turn off the ignition and turn it back on and the beep would go away for a minute. When I got back to the ramp I took off the cover on the side of the engine and where the anti-syphon valve is, the previous owner had cut off the end and hooked it up directly to the engine. The top connector had nothing hooked up to it. What's weird is this is the first time it has done this. It has been running great before. The engine isn't hot either. Would the way the gas line is hooked up to the engine without an anti-syphon valve cause this? Any other ideas. Sorry it's so long. Thanks.

Re: Warning buzzer

White smoke is not a good sign. The steady beep as was pointed out is an overheat warning. You very likely have a blown head gasket due to running the engine in an overheat condition. The overheat was likely due to a thermostat that stuck shut. And just so you know, just because the water pump is pumping water doesn't mean the engine can't over heat. If cooling water can't get out of the engine faster than its being heated, you have an overheat. Since you are mixing oil & gas, the Oil warning can be disabled by disconnecting the oil pump electrical harness under the VRO pump.

Silvertip,

How hard is it to change a head gasket and is there a way to definitely tell if that's it? Also, where are the thermostats located on this engine? Thanks.

Re: Warning buzzer

Not hard to change. No special tools required. A socket set and torque wrench are all thats required. Torque wrench can be rented or some auto stores have a loaner program. Run a compression test. Low compression on one cylinder or low compression on adjacent cylinders would confirm. Be aware that low or no compression can be due to other problems as well -- such as a burned piston, scored cylinder or broken or stuck rings. Compression testers are available for 25 dollars or so at any auto store or any department store that sell auto parts and accessories. Farm stores are a good source as well.

Re: Warning buzzer

Forgot to mention that you should also fix the "cause" of the problem, not just the "effect". change the thermostat(s) to ensure it/they don't cause the problem again.
