The hydrodynamic One-Drive® system features a unique electromagnetically actuated hydraulic clutch for exceptional smoothness and quiet operation. Especially noticeable in the twin engine configuration, the hydraulic clutch system quietly engages and disengages gears at an incredibly responsive two-shifts-per-second.

Each drive is outfitted with precision-forged gears for exceptional durability, counter-rotating propellers for superior acceleration, and large rudder dimensions for excellent handling on single and twin engine boats. The One-Drive transom has a significantly larger exhaust output than comparable systems, minimizing backpressure for improved engine performance. The system is also equipped with the latest in active and passive corrosion protection, and is complete with power-assisted steering and hydraulic trim.

In short, the One-Drive offers a driving experience that sets it apart, and above, other sterndrives in the market. Additionally, the Ilmor One-Drive can be customized with an added aesthetic effect.
