WHELL GUYS NOW THAT ITS RUNING BETTER, I NEED TO KNOW IF IT IS RUNNING HOT OR NOT I CHANGE THE PUMP AND HAVE FELT THE HEADS AND IT IS PUMPING AND COOLING BUT NOW I WANT TO TRUST THE GAGE AND THE HORN .IF IT HAS ONE , NO HORN SOUNDS WHEN YOU TURN THE KEY AND LEAVE IT AS ON THE MERCRUSER,I /O HOW CAN YOU TEST THE TEMP SENSER. IS ONE SENSER,IN THE HEAD FOR THRE GAGE AND THE OTHER ONE FOR THE HORN? THERE IS A BLACK BOX,UNDER THE CONSOLE THAT HAS 2 PLUGS GOING TO IT;ONE FROME THE VRO TANK THE OTHER GOES INTO THE WIREING HARNESS. SHOULD THERE BE A WARNING SYSTEM FOR THE VRO? ON MY MERCRUSER IT HAT A LOW OIL PRES HORN TEMP HORN. A TEMP GAGE AND WOULD NOT LET THE MOTOR REV IF THEY WERE ACTIVATED.. THE KEY AND THROTTLE ARE A MOSS CONTROLE SYSTEM I THINK WOULD THE HORN BE IN THERE ?
