Two weeks ago I grenaded my existing impeller (didn't change it last year so, I deserved the on the water repair), pulled out my new spare which was probably a couple years old but, new in package. Put it in and went my merry way. Two weeks later, put the boat in the water and got a days use out of the new impeller, then on the third day on the new impeller, just after launching and waiting to pick up, the new impeller grenades. I pull out the raw water pump to find that there weren't any pieces larger than my pinky nail.
Has anybody grenaded a new impeller?
I can only attribute the 2nd failure to an aged impeller.
