Hello all, had a question about warning horns. I am getting 1 long contious horn after start up at low speed. Shut it down and start again and all is good even after a hard day of tubing. This is a 06 105 Opti fuel injected. Does anyone know is that warning horn overheat or low oil. I have approx. 1/2 tank of oil or less. This has me a littlie freaked because when I bought this thing the powerhead blew due to overheat from a manufactering problem and I by no way run this thing hard, I baby it. Mercuy warrantied the motor but now I am constantly looking over my shoulder especially if it a overheat problem since I am out of warranty.....thanks
