At the very crux of engineering is the desire to problem-solve, optimize, and squeeze out every bit of efficiency possible from the system being built. Aircraft design and aeronautical engineering ...

As triple- and quadruple-outboard-powered boats increase in popularity, choosing the best mix of propellers for such propulsion systems has grown in complexity. That’s because center engines sometimes ...

Propellers affect more than speed and fuel economy. In fact, the more outboards there are hanging on the transom, the more propeller selection dictates a boat’s ride, minimum planing speed, and ...
