I'll probably go back to the 4S stainless that came with my new motor for the little extra speed, though. I'm also thinking about installing a set of Nauticus Smart Tabs to try improving the hole shot  rotus623: As you have already determined even though you didn't find a part number, the impeller in your motor is aluminum. The aluminum ones use a different key  than the SS ones. The SS impellers use a square key. . I didn't buy the 4S SS impeller, it came in my motor. Buying an impeller could be complicated since the part numbers (855708T60) are the same on both the 2S & 4S. The 2S in my photo was bought in June, 2014 from https://mercuryperformance.com/index.php for around $320 including shipping. But I don't know which type you would get now if you bought one using that part number. You can also find them on eBay for around $330. Jet Doctor has the same impeller for $410, probably close to $450 by the time you paid shipping. A dealer would likely charge you about the same as the Jet Dr, but at least you could look at before buying it and see which type you actually have.</blockquote>
