I had an old Black Max 150 on my bottom painted 83 which was fine as I cant get up any speed in the ocean..about 33-34 that was plenty fast for me. If I lived on a big lake or protected river and wanted to pull kids on tubes or knee boards or fished with 3 guys then the 200 would be a big improvement if its a two stroke. Some of the big 4 strokes will be very heavy and can put your scuppers below the water line which I've never been comfortable with..but thats just me . Frank
