Maintenance is minimal: it is limited to a simple grease top-up and replacing the sacrificial zinc anode, with no need to replace other components even after many years of use.

Standard catalog tapers are 1:10, 1:12, and 1:16.

Should you require a different taper for specific needs, Max Prop is at your complete disposal to evaluate feasibility and manufacture custom orders.

The key elements that define a propeller's performance are pitch and diameter. Compared to these, all other characteristics play a secondary role.

Between pitch and diameter, pitch is the most crucial element in determining performance:

• Modifying the diameter (even significantly) has a relatively minor impact on overall performance.
• Conversely, even a small variation in pitch—for the same diameter—produces quite noticeable effects.

The number of blades also plays a secondary role compared to diameter and pitch. The two main (albeit modest) influences of blade count are:

• Noise reduction: Under specific sailing conditions, a propeller with a higher number of blades (preferably an odd number) is generally quieter than the same propeller with fewer blades.
• Theoretical optimal diameter: Relative to an optimal three-blade propeller, the optimal diameter varies as follows:
  Two-blade propeller: 3% larger diameter
  Four-blade propeller: 2.5% smaller diameter
  Five-blade propeller: 4% smaller diameter

To make a realistic comparison between different propellers, you must evaluate one specific requirement at a time. Every boat owner has different priorities—such as maximum cruising range (lowest fuel consumption per mile), top speed, maximum maneuvering efficiency, or overall cruising comfort.

To best meet each specific goal, a tailored pitch is required—making it essential to have a propeller that allows you to adjust the pitch.

The Max Prop team is available to offer tailored advice for your specific needs.
