90-115hp Command Thrust
None More Durable. Or Efficient.
Heavier boats used for pleasure, fishing or commercial applications often sit high on the water and are hydro-dynamically different from other lighter boats. To address those differences and in response to additional challenges, Mercury developed its Command Thrust family of outboards.
