Compatibility should always be verified before ordering. Our technical team can review your engine model, serial number, and vessel specifications to confirm suitability.

Understanding the 2.49:1 Reduction Ratio

The 2.49:1 reduction ratio is designed for applications requiring greater propeller torque and enhanced thrust generation. By reducing propeller shaft speed relative to engine speed, this ratio allows the use of larger and more efficient propellers, particularly beneficial for heavier sailing yachts and offshore cruising vessels.

Benefits of the 2.49:1 reduction ratio include:

• Increased propeller thrust
• Enhanced low-speed control
• Improved maneuverability when docking
• Better propulsion efficiency under load
• Optimized cruising performance

Selecting the correct reduction ratio is critical to maximizing the performance and efficiency of a complete Yanmar propulsion system.

Extended Length Saildrive Configuration

The SD60-4-2.49-L utilizes an extended-length saildrive housing designed for vessels requiring additional saildrive depth and propeller positioning.

Advantages of the extended-length configuration include:

• Proper propeller immersion
• Improved hull clearance
• Optimized propulsion geometry
• Enhanced installation flexibility
• Compatibility with specific sailboat designs

For vessel owners replacing an existing saildrive, selecting the correct housing length is just as important as selecting the correct gear ratio.
