If your plastic one has melted it might be worth checking how much water is being pumped into the exhaust before you replace it because you might have a problem

Hi Don,
Thank you and thought as much, impeller okay, mixing elbow was a bit choked up , engine temp okay
strainer had a small amount of weed but okay also. The heat distortion temp on the glass is 130 deg so reckon I will be fine now , plastic one was pretty old like skipper

If you had an exhaust temperature sensor/alarm fitted........?

Problem is the distortion temp of plastic is so much lower than glass
Fibreglass can handle the temp from a short period of nil water flow , plastic cannot
