Available for all saildrive engines
Line cutter saildrive
Suitable for the Max Prop Easy® Saildrive and Max Prop Antishock® Saildrive models.
The new Max Prop® Line Cutter is designed to provide additional protection for the saildrive unit while sailing.
Integrated directly into the propeller and manufactured from 17-4PH stainless steel, it cuts fishing lines, plastic bags and other materials that could become wrapped around the saildrive leg.
It provides a discreet yet highly effective and durable solution, without increasing the propeller’s overall dimensions.
This device is available on new Max Prop® propellers for saildrive applications, both with and without the Antishock system.
Designed down to the smallest detail for a safe, compact and light weight propeller
Minimum drag while sailing (Low Drag Propeller)
- The blades rotate mechanically, maintaining the same thrust profile and therefore maximum efficiency in both forward and reverse, while minimizing the vessel’s sideways movement.
- The propeller is supplied ready for installation on the propeller shaft, already assembled and greased, with the pitch settings preset.
- Extremely easy to install, even with the boat in the water.
- Forward and reverse pitch settings are independent of each other.
- The pitch can be adjusted precisely in 0.5-degree increments. Adjustment is very simple and can also be carried out while the boat is in the water.
- Outstanding reliability and virtually unlimited service life.
No special maintenance is required; over the years, only periodic greasing of the propeller and replacement of the zinc anode are necessary. - If the engine or propulsion system is changed, the Max Prop® model with integrated Line Cutter allows the direction of rotation to be reversed without replacing the propeller.
- Easy to remove from the propeller shaft, even after many years of use.
Max Prop ® propellers
Ready-to-use Propeller
Max Prop® propellers are delivered fully assembled, greased, and with pitch values preset, ready to be used. Installation on the propeller shaft is much safer and faster compared to fixed-blade propellers, requiring only a couple of minutes and capable of being performed by anyone, even directly in the water.

Frequently Asked Questions
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.
