The warning alarm is going off on my '97 150 HP Mercury outboard. I was
ready to change the impeller since water doesn't come out the pee hole
for about 30 seconds after a cold start, and the stream doesn't seem as
strong as usual. What didn't make sense is that the alarm goes off as
soon as the engine is started. It seems to idle around 160 F with ear
muffs on.

I tried switching the garden hose back and forth between the ear muffs
and the fitting next to the pee hole to try to flush any junk out.
After about three repetitions the alarm stopped going off but came back
on after I started the motor a few more times.

Thanks for any help,
Jim

I am not sure without checking the book, but you may have both a water
pressure, and water temperature alarm sensor. If you don't have a tach
with the individual warning lights, then all of your alarm sensors will
beep through the same beeper, and it is hard to know which sensor is
actually causing the alarm. The strangest impeller malfunction I ever
saw was where the bronze keyed bushing was spinning inside the impeller,
and like your case, there was slow water flow, and the motor would
overheat above 1/2 throttle.
