Last season we were out in my buddies welcraft with CAT's. We were running across the bay and the luckily i was paying close attention to the semi working gauges! I noticed the temp move just a hair on one of the motors luckily i reached for the throttles and pulled back. by the time i got to an idle the temp peg'd. To the point where the paint changed color on the motor!
Caught it just in time!
a 1/4" coolant line broke and dumped all the coolant!
If it wasnt caught in time it would have melted down!
