I think the main trade off is simply in re-balancing the boat in any of the traditional ways. Slide the console forward a bit, move batteries or fuel tank forward or add ballast forward. Or better yet, get a couple of babes to ride with you and place them where you need them. Might be as simple as having 2 riders for of the console
.
I don't think it would be nearly as dramatic as if you were moving the additional 100lbs of a 150 hp motor 2' aft, but some re-balancing would be in order.
