I have a 15ft or 4.6 meter nautiglass half cab 78 model. <br />I use the boat to go outside fishing and in lakes as well. <br />It has a 55hp chrysler on it now which is to small for crossing a bar at times. <br />What would be an ideal size for the boat if i put a brand new 2 stroke on it. <br />PS. The transom is rated to 85 hp.<br />regards moorbee
