I've actually gone through the whole thing and am happy to share what I've learned. It is an amazing setup but takes quite a bit of effort to complete. Can post pics if anyone is interested. I'll watch this thread.
Here are some quick thoughts.
You absolutely must be handy since much is left to your imagination.. Instructions are mostly useless. Very little is explained. A few pics are included but interpretation requires real imagination.
I ordered from Kayak Excursions in FL and found Stefan hugely helpful and patient on the phone. Steve is also available at bassyaks, when he is available

Voltmeter is highly recommended. This boat will use up power a bit faster than other since it is heavy. Haven't run out yet but thinking its been to about 25%.
The motor needs to operate as deep as the shaft will allow since the stern is high up compared to other kayaks. Otherwise lots of cavitation. This makes cable lifting and or stowing of the motor much harder since the pivot point on the shaft is very high. Can't really test this in the garage since without being submerged, the motor is too heavy to be cable stowed.
Power-Tec 55 amp/hr AGM is a good match for the 45 lb. thrust. No motor weaker than 45 lbs.
Still not sure what the lift kit includes for $55 even though I have it. Maybe the cleat and flimsy elastic cord to elevate the motor. Probably a good idea.
Lower circular clamp on motor shaft has to be finely adjusted to prevent the motor from flopping on its side and also providing any hope of getting it to lift and stow by feet. I usually just recline the seat and reach back. Still trying to figure it out after 10 excursions.
Foot rails seem a bit flimsy and may required fiddling around to get right. I had to buy nylon washer/bushings to get them to fit and not bind. Too bad the Jackson rudder kit foot pedals cannot be bought separately. Would be much better.
If you find yourself in the water for any reason, the foot pedal rails will make it
very hard to get back in. I recommend either getting back in at the stern and climbing over the seat, or do what I did. Buy a paddle float so you can have an outrigger to grab. You can put one foot in the stand up strap and grap the paddle. I always carry the paddle float in case. Hate to die of hypothermia because of a bassyaks design oversite.
The steering cable love to bind. First, the cables have to pass through the hull twice. Also, if the pedal rails aren't absolutely true (very hard to get) binding becomes a real problem. Have to push the pedal too hard on a slightly warped (if untrue) track. One cannot simply redrill 1/16" away from the original site to correct it.
The thumbscrews for the steering cables are a pain. I was warned about overtightening but the real issue is undertightening. If you push hard to steer (seems required on this rig) you risk stripping the plastic off of the steering cable. That makes it very hard to reposition the foot pedals when transitioning from solo to tandem.
Well that is a sampling of things I encountered. If anyone requests, I can add pics and post vids on youtube. Good luck! It took me 3 weeks but now there is true kayak happiness.
