Get the best deal on a two cycle as close to the max that your dingy can handle. When cruising these are our main harbor transportation. If the weather is bad you will appreciate the increased power and if the weathe is fine you will like it even more. I have an old avon
rig and has to down size from a 15hp to a 9.8 Nissan because of weight, I am getting older. The 9.8 barley planes the boat with my wife and me in it, but I can put it in on the dingy in less than perfect conditions. I also have a hoist and davits for the dingy which I greatly appreciate.
