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?
