One word of advice; the universal built in transducer is an option on some models. I feel it is well worth the money to get one with the built in transucer so you dont have to figure out how to mount it and worry about twisting the cord up in the TM shaft. You have to buy an adaptor cable to interface your unit with the TM. They run around $45.

While I am spending your money, I also strongly recommend the quick disconnect mounting plate as well. It makes intallation a breeze and you can remove the motor in seconds. I have to keep mine outside under a cover and the I-Pilot mount sticks out beyond the front of the boat so being able to slide it back into the boat so the cover fits snuggly over the bow is nice. This also is a good feature if you have to leave your boat out overnight and are worried about someone stealing the TM. It comes off in a jiffy and you can lock it in your vehicle or motel room if you are on a trip.
