I have mine mounted on my WE 754VS. It does not come with the troller mount like yours but is mounted in the same place. I have never noticed a real problem with it steering or holding a course. Naturally it would be just a little better right over center but I didn't like the idea of the tradeoff's you have when mounted that way ( motor has to be mounted quite a bit forward so good chance of busting covers on winch or roller, head sticking out over side of boat when trailering, harder to retrieve motor at that angle, could be in your way getting in and out of boat)
