Thanks for the response Fishinman91!

Update:

The boat has been ordered. I'm semi-set on the following for a trolling motor.

Terrova 55 AP/US2 1366150 YES YES 55# 12V 48" $938.27

The price is a bit higher than I had in mind; but the Terrova appears to be pretty popular here and the options seem to be endorsed pretty heavily.

Does this trolling motor influence fishfinder choices?

Does the recommended Humminbird 565 work well with the built transducer on this trolling motor?

Would a little more money get me a bigger screen or better shallow water resolution?

I'm leaning towards the Optima batteries. Any negatives besides price?

Thanks in advance!
