Thought I would share a great product.
Had a water pump fail at WOT and was distracted so missed temp gauge rising. It was already maxed before the alarm kicked in. By the time the alarm kicked on, coolant vapor was emitting everywhere. After replacing the pump, hoses, therm and coolant I found a great product. It measures the raw water side of the cooling system. In theory, if I lose another pump, my raw water alarm will go off way before my coolant overheats again. I put her through some rough trials to see what the hottest temp I could get the raw water side. I then set the alarms 10 degrees above that and I feel a whole lot better!
They come as two large digital displays which mount right on your helm. You wire up two sensors to your exhaust hoses and set your alarm threshold. Love it and have a lot more confidence on the water!
NASA Marine Instruments - EX-1 temp sensor / alarm.
Well worth the money and they weren't that expensive.
