Trolling Motor for new Inflatable Boat

[Kayakin' Kelley]

Greetings one and all.

I was talking to Lefty and he thought y'all would have good input for me.

I have been wanting to get out on the water and do some fishing but $$$$ is tight for me. So I have purchased a Sea Eagle SE 9. (Fisherman's dream package)
Motormount Boats

What I am hoping y'all could help me with are ideas on what kind of electric trolling motor I could get? I'm looking to go 4 mph max, but I want to be able to stay out on the lakes and rivers for a while.

What I am looking at doing is getting out with my son so we could go out fishing when Lefty takes his 'yak out.

Thanks!

Kelley
