New Volvo Penta DP-D1 1.95:1 Ratio Sterndrive. Open Box, Never Used!
The Volvo Penta DP-D1 is a dual-propeller marine sterndrive featuring a counter-rotating propeller system for superior grip and handling. It uses high-performance internal gears and is engineered to transfer maximum torque efficiently while resisting harsh marine environments.

MECHANICAL DETAILS
Gear Ratio (1.95:1): This is a reduction gear ratio. For every 1.95 revolutions of the engine, the upper drive shaft turns 1 revolution. This ratio is optimized for high-torque diesel applications, allowing the engine to reach its optimal RPM range while swinging larger propellers.
Silent Shift (Cone Clutch): unlike older "dog clutch" systems that mesh metal teeth (often with a loud "clunk"), the DP-D uses a cone-shaped clutch that engages via friction. This allows for near-instantaneous, smooth, and quiet shifting into Forward and Reverse.
Duoprop System: This eliminates propeller torque steer, provides superior grip/traction, and improves planing efficiency by roughly 10-15% compared to single prop drives.
