Once you outgrow a tiny inflatable, your next tender will likely be a 10' RIB. The best power/weight combination for it is usually a 15-hp outboard. Almost every manufacturer offers one, and at first glance they all seem about the same. We tested five long-shaft models with an electric start. They had remote steering options and ran within 1 mph of one another. When weighed with oil and fuel, all came in at about 115 pounds. And at wide open throttle, they all measured around 97 dB-A. But, as we found out, there are important differences that don't show up until you live with them.
