Warning Buzzer

[bzz]

I Am Having A Problem W/ 1999 Force 120. At 3800 Or Below Rpm, I Can Run All Day. At Higher Or W.o.t. My Buzzer Goes Off. I Let It Idle A Little It Goes Off And I Go On My Way. I Thought It Was The Thermo- I Spoke W/ Don At Sierra Marine And He Said I Should Have A 14o Degree In There. I Tested W/o A Therm In And Got The Same Problem. I Have A New Impeller And Water Pump Kit In. Any Ideas?

Re: Warning Buzzer

Just a stab here, impeller slipping at higher speeds?

Re: Warning Buzzer

How did your water pump houseing look or did you replace it also?

If not I would look at it, if there is any pitting or scraches it will let water bypass and not pump as much up to the motor at high speeds, also the pitting will "sand "the empeller ends flat thus not forceing the water up the tube.

And if the woodruf key was installed wrong you would have the slipping baxtr said.

Actually, according to my Clymer's manual, the impeller actually forces the water up the tube by rubbing the water pump housing at low speeds only.

At high speeds, the impeller is spinning so fast that it's actually forcing the water by means of centrifugal force. The impeller fins don't even hit the pump housing at high speeds.

True.


Sari, slow speed prob could be worn out impeller or an obstruction
