Having now used the Hobie eVolve Torqeedo electric kayak motor for a couple months now, I thought I would share my experience and opinions about the motor.
Pros
Cons
What you get
Installation
It took me about 2 hours to install on my rudder. There are 3 holes to drill in the kayak. I placed my battery in the forward hatch to help offset the weight of the motor on the back. I mounted the remote throttle in the storage area forward of the right-side cup holder (Revo 11).
Rudder Mount vs Mirage Well Mount
I chose to mount it on my rudder, because I still use the Mirage drive a lot. I also like being able to stow the rudder/motor it in shallow water.
Twist & Stow Issues
The weight of the motor on the rudder makes it very difficult to stow and deploy the rudder using the stock up and down lines. In order to resolve this problem, I created a pulley system on the lines to make them easier to pull. With a 2:1 purchase it is twice as easy to pull the rudder up or down, at the expense of having to pull it twice as far. It is now EASY to pull up.

The motor will stop completely if:
What they could do better (aside from the obvious faster, longer, lighter)
Run Time
It takes maybe 8-10 hours to fully charge the battery. By plugging the remote throttle into the battery while charging, you are able to see the charge level.
On a full charge, your mileage will vary greatly, depending on current, wind, waves, weight and throttle. The remote display is very useful in finding that sweet spot. I find that in many situations, full throttle only gets me about 0.4 MPH faster than half throttle. You can get from 3-20 miles on a charge. That is a wide range and it depends on the factors mentioned above. Usually, I will get about 8 miles. You can run about 18 hours at low throttle to, for example, stay stationary in current (that's why I would prefer to see the remaining time rather than distance... distance is always 0 when you're not moving.)
Conclusion
Bottom line, I love it because it allows me to fish more.
Pros
- More fishing: you get to the fishing grounds faster, you can go farther and longer.
- Reverse: Reverse on a Hobie without a paddle! Nice.
- Shallow water: The motor will work in shallower water than the mirage drive.
- Rig en-route: With both hands free, and nothing to do with your legs, you are free to rig up as you cruise towards the fishing spot. Just watch where you're going.
- Move while sideways sitting: you can move while seated sideways on the kayak. This has proven particularly useful at kiptopeke, sideways sitting in front of the holes in the ships.
- Prevent drifting while unhooking: Put just enough throttle to keep stationary against the current, and you can unhook, photograph and thank your fish without drifting halfway down the bay.
- Make headway in heavy current: in heavy current, you can make better headway by using the motor and the mirage drive together.
- Turn on a dime.
Cons
- It's freaking expensive. At almost $2000, it's more expensive than most kayaks. $700 of that total price is the battery.
- Adds 18lbs to your kayak.
- One more thing to charge.
- 2 more things to put on the kayak before launch and to take off afterwards (battery + remote throttle)
- Rudder is less effective when unpowered: although the motor assembly does work relatively well as a rudder, it is not nearly as good as the original or sailing rudder. Under power however, even very little power, it turns very well.
- Rudder is more difficult to deploy/stow. (This can be fixed, see below.)
- Fishing line can get stuck in prop.
- Potentially less exercize, but that's really up to you.
- A little noisy.
What you get
- Motor
- Mirage drive motor assembly: You can drop it into your mirage drive well.
- Rudder motor assembly: With some realtively easy modifications, the motor attaches seamlessly to the rudder twist & stow assembly. It replaces the rudder blade.
- Remote Throttle: It's what you use to control your throttle. It also displays remaining charge, speed, throttle and range. It attaches using a ram mount.
- Battery: Sealed/Waterproof Lithium-Manganese high-performance battery - 320 Wh (11Ah at 29.6V). The battery houses the GPS receiver.
- Cables: A fat cable goes from the battery to the motor. A small cable goes from the battery to the remote throttle.
- Battery charger
- Mounting Hardware: ram ball and arm and various nuts and bolts, seals, cable caps, etc...

Safeties
The motor will stop completely if:
- The magnetic key detaches from the remote throttle
- The angle of the motor becomes unusual because you have hit something or turtled
What they could do better (aside from the obvious faster, longer, lighter)
- Remote Throttle: Scotty, beam this thing back to 1970! It looks like a prop from Star Trek. They really could have done better. It's too big. The throttle arm is on the left... it should be on the right to avoid your legs accidentally hitting it while pedalling. The display will tell you, in miles, how much farther you can go on the remaining charge at the current throttle. If for some reason you are not able to get a GPS signal, it will display, instead, how much time you have left on the remaining charge. I actually prefer knowing how much time I have left (rather than distance), but there is no way to see that if the GPS is working. It would be nice if you could toggle that. The display is hard to read in the sun, especially when salt water has splashed it.
- Rudder control: with just a little more surface area, they could have made the rudder a lot more effective when unpowered. I know several other guys who have modified their evolves to improve their rudder control.
