Mercury Marine 4.5L 200HP Sterndrive Engine
Mercury 4.5L 200hp sterndrive engine review
The Mercury 4.5L 200hp sterndrive engine has a host of exceptional features
Designed and manufactured at Mercury Marine’s world headquarters in Wisconsin, USA their new 4.5L 200hp sterndrive is based on the 4.5L 250hp sterndrive they introduced last year.
Since then the MerCruiser 4.5L has established new standards for acceleration and overall performance, with design innovations such as a long runner scrolled intake manifold and high displacement which produces an outstanding power-to-weight ratio.
Mercury says their new 4.5L engine delivers maximum fuel efficiency and exceptionally quiet operation.
The rear-facing throttle body, anti-whistle throttle plate, engine cover and mounts, lightweight flywheel, fuel supply module, and structural oil pan are all newly designed
This all works together to deliver superior sound quality and smoothness from idle all the way through the power band for a better boating experience.
The 4.5L V6 also offers Adaptive Speed Control (ASC)
Adaptive Speed Control (ASC) automatically maintains the set rpm point regardless of load or condition changes, such as tight turns, tow sports and lower speeds on plane. The result is increased throttle response and a sportier feel for the driver, who no longer has to make continual throttle-control adjustments.
The new engine has exceptional anti-corrosion protection, using durable cast-iron componentry wherever the engine encounters seawater, and corrosion-resistant aluminium and composites everywhere else. Digital rather than analogue sensors are used throughout.
