I notice that there is a scraped spot on the inside where apparently the fan blades rubbed during operation at least once, but I'm pretty sure it was not pinched there in its working install position... or was it?
Even on the old metal ones you could tighten the hose clamps tight enough to make the fan blades scrape the housing. In fact, that's how I lost mine... because I was scared of over tightening them and I ended up leaving them to loose.
As for the difference in wattage Kermit, look at the post above yours for the words "custom winding". Most likely they rewound it with a slightly thicker gauge to handle the 12V car battery and it's different amperage discharge rates when compared to the 7.2V or 8.4V batteries most model engines are designed for.
