MIAMI—Outboard motor manufacturer Seven Marine introduced new 527-hp and 577-hp versions and a redesigned 627-hp model of its engine that is based on a GM LS V-8 engine. All the motors are also offered with the company’s new twin-prop CR (contra-rotating) gearcase.
“Since the foundation of Seven Marine, our passion has been to improve the outboard experience,” said Rick Davis, Seven Marine president and CEO in a statement. “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, with our Outboard Portfolio, we’re optimizing our product range to adapt to the ever-changing style, performance and reliability requirements of the expanding outboard market.”
The new outboards are built on Seven Marine’s 6.2-liter supercharged V8 platform that features closed cooling, wet-disc clutch transmission and fuel injection. The new 527 has a 1.91:1 gear ratio option that is intended for use on bigger, heavier boats. The 577 is more of a luxury offering with a Spectra-Lite lighting package with LED illumination on the rear of the motor. The redesigned 627 is targeted at large offshore boats. The existing 557 is being phased out and will be replaced by the 527 and 577.
Seven’s new CR gearcase is offered with all three of the new outboards. It supports the largest blade area in the industry ranging from 18 to 19.5 inches with four- or five-blade propellers, according to the company. The lower unit is designed for large outboard powered boats weight between 20,000 and 65,000 pounds with gear-ratio options ranging from 1.96:1 to 2.55:1.
The company also offers the single-prop twin pinion gearcases in standard and GT versions. The single-prop units are for boats running between 60 and 85 mph and the CR model is for heavier boats that run less than 60 mph.
Finally, Seven Marine also introduced an extended warranty at the show. The engines come standard with a three-year warranty and an additional two years are an available option.
