92 Yamaha 115 outboard warning horn beeps
My 92 Yamaha 115hp outboard ran low on oil (not empty) recently,
activating the warning horn, and cutting rpm back to 2000 rpm. I
refilled with oil, and have a pointer triangle above the full oil
indicator. Now it runs strong for about 5 minutes then I hear one beep
from the audible horn followed by the motor cutting back to 2000 rpm.
If I reduce to idle for a minute or so, I can resume at full speed for
another 5 minutes. Oil is full with a triangle pointing at the green
full indication. However, the red empty indicator has a red square
above it, where the triangle pointer would go. I don't remember if the
red square was there before this happened or not.Does this sound like it is overheating, or is the oil level sensor
malfunctioning? Also, is it normal to have that small red square above
the empty indicator, or is that a holdover from letting it run low. Thanks, Lee |

| Thanks, I think so too. It will run all day at 2500 rpm, but does the
horn/rpm reduction thing after running at 4000 rpm for a few minutes. Also found out today that the red square above the low oil indicator is
normal. They come that way from the factory. Lee |

| My 84 yamys' use the same warning buzzer/red light regardless
if they are low on oil or overheat. Sounds like an overheating problemo to me. Might want to check your
impeller. db <ghankins@yahoo.com> wrote in message |
