I got one with my 591. It fits very good and tight. I was amazed at how the little soft felt pads on the underside of the cover hit exactly in the right spot to avoid damage either to or from things like the trolling motor or windshields. My only grumble is the archaic rope tie back at the motor....there's got to be a better way.
It did leak the first time I had it in the rain but I didn't think much about it. It was a heavy rain that lasted all night and a brand new cover that hadn't had a seam sealer applied yet. I'm sure that you can find nicer covers but for the price of it, I think it's a heck of a cover.
