I fell for all the nice spec’s that are out there about the blue Globe impellers, but what a fraud. It didn’t last more that 40 hours. Once I friend told me I should stay away from these but I didn’t listen. Know it’s my turn to alert other. I almost fried my engine. I even threw away the other one I bought for replacement. For your safety, stay with the original Yanmar black impellers.
Bingo!!!! LOTS of bad luck with Globe and lots of others with failures too...
Just a heads up..
I've tried the Globe impellers but found them very problematic. Below are some quotes and photos from another forum. My failures were the center hub spinning free of the blue impeller. This was a tough one to trouble shoot as it looked fine. The next one the tolerances were off ever so slightly and she would not "prime".

I will be taking it back tomorrow. Also going back to rubber type (black)
Sorry the pics are not the best

It has never run dry.
It appears that they have changed materials and that these impellers are now junk. I guess I will be going back to the black ones also. Too bad they had a good product. I was considering using their motor mounts but I think I will look elsewhere.

Reprimed the the pump and restarted the engine. Water flow out the back was not normal. Shut down again and pulled the impeller apart. The pictures show the condition of the Globe impeller. It was less than 3 months old, never run dry. It probably ran 20-25 minutes at less than full water flow and never saw temps above 170°. Not buying the 15 minutes run dry.
Just an FYI that the Globe impellers are NOT all they are CRACKED up to be..
I replace yearly... Engines are 15k my impeller is $16.00 or about the price of a 12 pack of decent beer..
