To me, if the hull is solid, then you are in a great position to make exactly what you want of her...I like an outboard myself and that's the way I'd go if it were me...will cost more (especially if you go new), but lots of deals on ebay etc on brackets and used OBs...opens up the floor space in back of boat and improves performance...hard to go wrong there...
Post up some pictures and let's see what ya got...
