As Seven Marine, the Wisconsin-based manufacturer of mega-power luxury outboards, notes the one-year anniversary of its partnership with Volvo Penta its portfolio has expanded to three models. The model line-up now includes the Seven 527, the Seven 577s and the Seven 627sv. In each case the model number indicates the outboard's peak horsepower rating. The Seven 527 and Seven 577s replace the Seven 557.

“Since the founding of Seven Marine, our passion has been to improve the outboard experience. Today, our new outboard portfolio furthers that vision,” said Rick Davis, Seven Marine President and CEO. “With the market introduction of the 557 seven years ago, we revolutionized the outboard industry with luxury, style and big power to carry larger boats. Now we’re optimizing our product range to adapt to the ever changing style, performance and reliability requirements of the expanding outboard market.”

Each of three Seven Marine models continues to use the supercharged 6.2-liter GM LSA Gen IV V8 engine with a closed cooling system. Power output is determined by supercharger boost pressure and electronic engine tuning.

The new Seven 527 is meant to make the brand more “obtainable” with a reduced price point, although Seven no longer publishes retail pricing – it’s a Volvo Penta thing. The Seven 527 has a redesigned, less-complex cowl that Seven says accounts for a big portion of its cost-savings effort. The Seven 527 cowl design also does not accommodate the LED lighting options offered on other Seven models, and will not be offered in the unlimited paint-and-finish options available for other Seven models. The Seven 527 is equipped with a new 1.91:1 gear ratio, which Seven says allows the motor to produce outstanding torque despite its lower peak power rating compared to other Seven models.

The Seven 577s is a full-feature model that comes with SpectraLight LED lighting (rear of cowl only) and has limited color options. The bump up in peak horsepower from 557 is achieved through engine tuning. The Seven 627sv features SpectraBlade LED lighting (on the rear, top and sides) and can be ordered with unlimited custom paint color options. Each of the Seven models are designed to make full power on 89-octane fuel.

Seven offers three gearcase options. The standard single-prop case is rated for up to 80 mph and can be paired with three different gear ratios. The CR case features four- or five-blade contra-rotating props and four ratio options. It is designed for speeds less than 60 mph and largest outboard boats weighing from 20,000 to 65,000 lbs. The Seven GT gearcase is a semi-surface piercing design for high-speed (above 85 mph) applications and has a bullet nose and tapered skeg.

European customers can soon benefit from the Seven experience. Certification for the European Union CE standard is being finalized and will be available soon for European shipments.
