On paper, the outboard power system is a clear winner. In this comparison, the Glastron GTS 180 with a Mercury 150 has the lightest weight, the best fuel economy, the quietest cockpit, and performance that matches or exceeds those of the sterndrive and jet. But the outboard loses big points for looks and the "livability" of its stern area. The jet is the least expensive, accelerates fastest, is easy to operate and has a clever lounging area, but it's thirsty and noisier. In this comparison, we think styling is really the only reason to choose the sterndrive-powered boat. We say, "Wise up, America!" and buy the outboard boat engine.
