Volvo Penta Ocean Propulsion Series

Volvo Penta Ocean Propulsion Series

Volvo's new Ocean Propulsion Series sterndrives are designed for boats in the 18- to 30-foot range, and for salt water fishermen who have traditionally relied on outboard power. The new system includes a bottom-up design of the outdrive, built with structural composites that decrease weight, improve impact protection and offer 10 percent less hydrodynamic drag than previous designs. The Ocean Series models feature an exclusive Neutra-Salt flushing system that removes interior salt deposits without the need for a fresh water flush. Remote oil filters and fuel-water separators are located where they are easy to service, and the oil reservoir is conveniently mounted on the engine for ease in checking oil and to reduce the chance of water intrusion in the gear case. The Ocean Series is compatible with a full range of EFI multi-port, four-stroke Volvo Penta gasoline powerplants: 4.3 OSi (225 hp), 5.0 OSi-XDP (270 hp) and the 5.7 OSXi-XDP (320 hp). All of these exceed the 2008 CARB and EPA emission requirements for 2- and 4-stroke outboards. Volvo Penta, Chesapeake, VA; (757) 436-2800; www.volvopenta.com.


Suzuki 140 Counter Rotation

Suzuki's 140-hp four-stroke outboard is now available with counter rotation for dual-engine installation, making a pair of these an excellent choice for large center consoles and other salt water fishing boats. Handling and control, especially in tight quarters, such as maneuvering in crowded marinas and docking are just a couple of the benefits of the counter-rotation configuration. At planing speeds, elimination of prop torque makes for easier handling and an even ride. It also provides excellent performance in combination with the in-line four-cylinder design and ready-to-rig weight of 421 pounds per motor. The 140 is packed with innovative design features, such as large dual overhead cams, four valves per cylinder, an offset driveshaft under the powerhead, 4-into-2 exhaust system, a water-cooled long-track intake manifold and the industry's first water-cooled oil cooler.

Converting Metric Horsepower

There are a couple of different designators that engine manufacturers use to identify the power output of their products. Historically, SAE horsepower has been the conventional measure of power output for U.S. manufacturers. This particular standard yields what is called brake horsepower (bhp). The last few years have seen a trend toward using metric horsepower (mhp), a German standard that is used throughout Europe. The mhp rating for a given engine is always a larger number than the bhp. While there may be some global advantage to using mhp, basically it provides a larger number that looks better from a marketing standpoint. Once one manufacturer began using mhp the rest felt compelled to do the same in order to remain competitive. There is a straight percentage conversion between the two ratings. According to Wes Hohulin, the marketing manager for Caterpillar America, metric horsepower rating is 1.4 percent higher than a brake horsepower rating for the same output. If you want to do the math, multiply the brake horsepower by 1.014 to get a metric horsepower rating. Or, divide the metric horsepower rating by 1.014 to get the brake horsepower rating.
