Options in outboards: from the summer of 2017, noteworthy technology news for the Florida boater.
Dual, contra-rotating props are the first thing you notice about the new Suzuki DF350A, but there's a lot more innovation packed into the company's new flagship V6. The propeller configuration, Suzuki engineers say, was selected to minimize the size of the gears, affording greater thrust and speed by way of a sleek, hydrodynamic gearcase. Added benefits include elimination of steering torque and improved performance in reverse gear. Topside, engineers wrested 350 horses out of a 4.4 liter, V6 powerplant through a class-leading 12.0:1 compression ratio. Helping garner those numbers are beefed-up pistons; dual injectors; and a unique, louvered, moisture-blocking, direct air-intake. The DF350A is available in 25- and 30-inch shaft models at 727 and 747 pounds, respectively. Mounting bolt positions match the DF300, making repower to 27-inch centers a cinch. Preliminary word on MSRP for the DF350A in 25-inch shaft and black was around $32,000. See www.suzuki.com.
Yamaha 4.2-liter 300 with Mechanical Control.
Daydreaming about repowering an older CC? Want four-stroke efficiency and reliability, with weight not far off that old two-stroke? Maybe you want to keep your existing control box and save some bucks on the repower? For all these reasons and more, Yamaha recently added a mechanical control version to its 300-horsepower 4.2-liter V6 Offshore series. The engine, available in both left and right-hand rotation (and--yes--in a digital electronic control version), brings four-stroke fuel efficiency, along with Yamaha's patented Shift Dampener System for smooth shifting. And, if you're replacing an older Yamaha V6 four-stroke (such as the F250 3.3 liter), you'll be pleased to discover that the new 4.2 liter engine is 50 pounds lighter: Plasma-fused sleeveless cylinders enabled an increase in displacement without enlarging the outer diameter of the cylinder. MSRP is $25,290 for right-hand rotation, and $25,870 for left-hand rotation. Seewww.Yamahaoutboards.com.
If you're considering buyinga pair of Evinrude E-TEC G2 engines, this fall you'll have the option of adding the company's recently introduced iDock joystick steering option. Designed for G2 twin installations from 150 to 300 horsepower, the system lets you side-step, pivot in place or nudge forward or astern by simply pressing or twisting a small, helm-mounted joystick. Take your fingers off the stick and the system incorporates a gyroscope sensor to maintain your course, regardless of wind or current. Two thrust levels are available--one for normal maneuvering and a boost if additional power is needed. Because the iDock system connects to the existing internal hydraulic steering of the G2 engine, there is no additional pumps or reservoirs to install belowdecks. Cost is $5,999, which covers the joystick, module and hydraulic hoses. See www.evinrude.com.
