Cat Builds More Powerful 2025-hp High Performance Engine

If you’re looking for power, pure power, the new CAT C32B’s got it – in spades. Indeed, this latest high-performance marine diesel from Caterpillar has 2025-hp, or 5 percent more than previous C32 engines. But it looks the same and has the same connection points and footprint, making it attractive for both new builds and repowering options. New from the block up, the C32B is built to run at wide-open throttle up to 8 percent of the time. Cat says this is at least 3 percent longer than competing engines can run at that speed. The C32B also delivers more muscle…

Yamaha Tests Revolutionary New Electric Motor. See Video

Yamaha is starting sea trials on Aug. 7 on its revolutionary electric drive system that provides greater maneuverability, faster turning, and less vibration and noise than possible on most conventional drives. Yamaha says its new HARMO drive package is a “next generation control system platform” with an electric motor, a remote-control box, and a joystick. It generates about 10-hp and is available in single or twin applications. A major innovation is that the  prop is not driven through a central axle, as it is in conventional motors.

BMW Making New 300-hp Diesel Outboard with OXE

BMW is working with OXE Marine to produce a co-branded 300-hp diesel outboard. OXE, a Swedish outboard company, already uses a BMW six-cylinder, bi-turbo diesel engine for its OXE300-Bison outboard. Under a new agreement, OXE said it will work with BMW to deliver the co-branded 300-hp outboards as “products of unprecedented power, reliability and endurance.” OXE also said it would continue to produce its 200-hp outboard through next year, based on a GM motor, but it also will test a marinized BMW powerhead as the same time to see if it can produce enough horsepower and torque while meeting emission…

Yamaha Launches First Joystick for Single-Outboard Boats

After three years of R&D, Yamaha just introduced the first joystick for boats with a single outboard. Until now, joystick controls were available only on boats with multiple engines.

With its power steering, you can turn the motor from lock-to-lock in less than two seconds. You maneuver the joystick in easy intervals. One short twist equals 1 degree of heading. A long twist produces 5 degrees of heading. A hold-and-twist repositions…

Yamaha Launches New Portable, Lightweight 25-hp Outboard

Yamaha’s new portable F25 outboard is a great answer for cruising people looking for lightweight power for a RIB or a dinghy or perhaps for a second boat.
