Command Performance.

Command Performance.

Sequential Multiport Fuel Injection regulates the precise amount of fuel required for different driving conditions, resulting in quick starts (regardless of temperature), smooth idling and improved throttle response. Power steering is standard, providing seamless, effortless control.

Rugged & Reliable.

Rugged & Reliable.

Engineered for maximum durability, these cast-iron engines keep their revs low for longer life. Mercury®’s innovative Cool Fuel Module – a water-cooled fuel-delivery system – prevents vapor lock, while Engine Guardian protects your power source from low oil pressure or overheating.

Corrosion Protection.

Corrosion Protection.

The MerCathode® system provides automatic protection against corrosive galvanic currents, while the MercFusion Paint System utilizes an electro-deposition primer for a superior seal. SeaCore®, which combines a closed-cooling system with industrial hardcoat anodizing, also is available.

Powerful & Efficient.

Powerful & Efficient.

A high-displacement small block engine may sound like a contradiction in terms, but in fact it’s a formula for success, tempering raw power with extreme efficiency. MPI and ECT work together to precisely calibrate fuel delivery, resulting in savings at the pump.
