Why Big Boats Stop at Six Outboard Engines

The most powerful center console on Earth runs six outboard engines and 3,600 horsepower. But no one has built one with seven. Why do big boats stop at six? In this video, we break down the real limit behind multi-engine boats: the 600 horsepower ceiling, why builders went from twins to quads, how weight, water flow, and transom space cap the engine count, and what the new 808 hp Mercury concept could change. Do you think boats will ever get past six engines? Tell me in the comments.
