Impeller Woes

Hi Capt Chris,

I thought you might like this picture of our generator impeller. The mechanic who replaced it said he hadn’t seen one “cooked” this bad in all his 40 years.

You have my permission to show future classes what happens to an impeller that gets overheated twice.

You may recall my story of woe. I forgot to open up the sea cock causing the generator to overheat and shut down. I soon realized what happened but failed to appreciate what had happened to the impeller. So the next day I opened the sea cock and ran the generator again. Predictably, it shut down and now we  see one destroyed impeller. Your future students should get a chuckle out of my story and wonder how anyone could do such a thing. It was a good lesson.

Thanks again for the great training session we had with you aboard Red Pearl Steve and Kathy
