Todays 9.9-horsepower four strokes pack just the right amount of punch for a portable dinghy engine. The downside, as you may have guessed, is their hefty weight. The three Practical Sailor tested range in weight from 82 to 92 pounds. All are two-cylinder, water-cooled engines that take about a quart of oil, and all are pull-start models, with chokes that need to be used only when the engine is cold. All come with a standard 3.1-gallon plastic fuel tank, a fuel hose, and an aluminum propeller. In terms of propulsion, none of these portable outboard engines has it all. So after evaluating how easy each was to operate, transport, store, and maintain, we based our recommendations on weighing each engines pluses and minuses.
