Gday guys just came back from a great day out when i was flushing the motors through the temperature gauge went off its face after about five mins of flushing. I noticed the prop wasn't spining (just in netrual) the othere one was and the tell tale wasn't spirting no where near as much water as the other one just a slight squirt. Could this be the impellar has craped itself the motors are due for there 100 hour service in 10 hours can ya change tthe impellar by yourself or should i let the boat shop do it thanks cheers Mick H

It's not uncommon for a V6 engine to overheat when running on a water hose due to low pressure or low volume of water from the garden hose. Try running motor at boat ramp to see if still overheats.
