I am looking at buying a Humminbird Helix 7 SI GPS G2N or a Helix 9 SI GPS and a Minnkota IPilot Link trolling motor.

The Helix 7 comes with a XNT-9-SI-180-T transducer.

Do I need to swap up to a better transducer?

I have a 17 ft Bass Tracker aluminum boat. Which trolling motor do you guys recommend? Is there a Powerdrive V2 with IPilot link?

What cables will I need to connect the Helix to the IPilot Link?

Thanks in advance for any advice.
