I am going to order another one now so I have a spare on board.
How old was the spare? Impellers do tend to harden over time, even in packaging. We have a replacement schedule for those in our spares. Then the other aspect, your boat is depending on a cheap little piece, probably cost a dollar to make, so how good is the consistency and quality control? Always has gotten me on equipment and boats, you have a $250k piece of machinery and you're at the mercy of a 50 cent piece of plastic.
