"I have a 1991 Evinrude 150 v6 spitfire series}}. The warning alarm keeps sounding off every so often. Cooling system is not even 1 yr.(new pump, thermostats, temp. sending units). Engine runs fine 2-3 outings then alarm goes off as soon as engine fires before even warming up. Engine pumps water strong."

(VRO Horn Warnings)
(J. Reeves)

1 - A steady constant beep = Overheating - The V/6 engines, possibly some others, have a fuel restriction warning which is also a steady constant beep.

2 - A beep every 20 or 40 seconds = oil level has dropped to 1/4 tank. (Late model engine = Every 40 seconds)

3 - A beep every other second = VRO failure, air leak in oil line, oil restriction, (anything that would result in a lack of oil being supplied to the engine).

NOTE - If the warning horn is the black plastic (overpriced) three wire type horn, the warning horn should beep once when the ignition key is turned to the ON position. If it does not, it is either faulty or someone has disconnected it (a stupid move!). At any rate, if it does not beep which indicates that the horn is non functional, find out why and do not run the engine until the problem is corrected.

(Odd Soundings Of Warning Horn)
(J. Reeves)

Should the warning horn beep constantly when the key is turned to the ON position rather than sounding just a short beep as it should, do the following test.

Remove the TAN wire from the horn. If the constant beeping continues, the horn is faulty, in which case replace it. However, on the other hand, if the beeping stops, something has gone wrong with one of the sensor components at the engine, in which case start disconnecting the TAN wires that are connected to the various components (Heat Sensors, VRO, Vacuum Switch if so equipped, Oil Tank). Disconnecting a unit and having the beeping stop...... you've found the faulty component.

NOTE: The small black plastic horn that has a built in black ground wire...... The TAN wire must be attached to the terminal closest to that black wire. Otherwise weird things will happen.

"The horn does a short beep when the key is turned on. The alarm went off this last time as soon as the engine fired with a steady constant beep. The engine was pumping a steady stream of water and the cylinder heads were hot, but not untouchable. I'll change the water separation filter and conduct the test you suggested. What should the spark plug color be? I checked them and they were a medium brown."

Please help - we just bought a used bass boat to restore w/ 1990 Johnson GT VRO 150hp warning buzzer is beeping about every 10 seconds and it seems that when she gets hot she shuts down and won't restart. It is pushing water thru just fine - is this about the oil level mentioned in earlier post? What can I do - I am a shadetree mechanic at best but willing to learn
