There are other prop makers who do props, and "power props" for all versions of Minn Kota. Both two and three bladed models are a direct conversion, bolt it on and go. I lay mine in the truck, so I needed to stick to two blades, but with extra batteries, set mounting on a boat, you can get more thrust, with a simple change. The factory props are "weed less" and that restricts the drive shape and more.

FWIW -
I have a Catalina 22 that I tried running a 24V Minn Kota Traxxis 80 trolling motor on. Granted - when you're in a SAILBOAT, you know you're not going to go that fast. But the fastest the Minn Kota would do was about 3.8mph (and that was at FULL POWER, going down wind with about a 10mph breeze, just no sails up...).
I've also tried a Torqeedo 2.0R and Torqeedo 4.0R on the same boat.
The Torqeedo 2.0R will easily push the C-22 faster than the Minn Kota at half the power. At full power, it will go substantially faster than the Minn Kota.
I have to believe that the prop on the respective motors has a LOT to do with this. The Torqeedo has a very large high pitch prop. All the trolling motors have much smaller props that are pitched to go a max of 3-4mph.
For the money ($600 at the time vs. about $3300?) - it seemed worth trying the trolling motor. The trolling motor definitely works - it definitely pushes the boat. Just not really fast.
What I'd love to have time to experiment with is putting the Torqeedo prop on the Traxxis motor, and see what happened then... I suspect you might have to keep the power down on the Traxxis to keep from overheating it - but that you would get much better performance in terms of speed.

Robert,
After running the boat, do you think the additional cost of the Torqeedo 2.0 over the 1003 with remote throttle (and custom modified steering) was worth it?
The reason I ask is that I am considering a similar setup on a 16' 1960 Penn Yan Baltic with an empty weight of about 550lbs. So far I have done some basic testing a few times with a 55lb Minn Kota 12V PWM trolling motor modified for remote throttle and steering with 'acceptable' results and run times for slow speed small lake cruising. Unfortunately, I wasn't able to take any measurements at the time however I did manage a 3 hour cruise at about 60% throttle with 3 adults and light gear on calm water until the integral LED battery meter was at 50%.
I am constantly going back and forth as to which route I want to ultimately pursue. The 1003 is less money, but the proprietary battery appears to be a possible drawback. Granted, having never seen one in person, I may be wrong.
