STANDARD FEATURES

• Durable. – Longevity is built in, from the cast-iron block and closed freshwater cooling system to the MercFusion-process electro-deposition paint. MerCathode®, an active cathodic anti-corrosion system, is standard with Bravo® drives. SeaCore®, which protects core components with hardcoat anodizing, also is available with Bravo.
• Effortless Efficiency. – This engine’s exceptional power-to-weight ratio enhances fuel economy, while the MPI system locks it in. ECT (Emissions Control Technology) works hand in hand with the MPI system and the CPU “brain” to further optimize efficiency and reduce emissions.
• Smooth Running. – The MPI system fine-tunes the fuel-to-air mixture in the combustion chamber, delivering ultra-smooth operation from idle to wide-open throttle. Mercury’s engineers achieved outstanding Noise / Vibration / Harshness (NVH) levels in the 4.3L. Power steering is standard, providing you complete and effortless control.
• Total Versatility. – Alpha® or Bravo® drive? Single or twins? MPI or ECT? Whether your vessel is a bowrider, cuddy, pontoon or houseboat, it’s easy to configure the perfect 4.3L sterndrive power package for long-range, reliable fun.
