I'm running the powerdrive v2 55# with co pilot on a 1756 xpress. If all your wanting to do is slow troll it's more than enough. I've never had a problem long lining with mine, even on windy days. As is said on here many times go as big as you can afford. Who wouldn't love the #112 pound thrust ul terra with the auto stow and deploy? But I can't afford it. If the powerdrive is in your price range get it, I'm pretty sure it will move you boat around it does mine.
