Italian Max-Prop range. 2, 3, 4 & 5 blade automatic self-feathering low drag propellers
|Darglow is pleased to be UK distributor for Max-Prop, low drag propellers. Since starting production in the 1970’s Max-Prop has proven itself on racing and cruising boats around the world. With over 65,000 propellers in the water, the Max-Prop is tested daily in the harshest conditions and has established itself as a world-leading propeller suitable for use on the smallest to largest yachts. The combination of low drag, outstanding reverse power, efficient forward performance and fail safe design makes Max-Prop the ideal Sailboat propeller on the market today. Now with the introduction of the ECOWIND, Max-Prop has taken a revolutionary step forward in the propulsion of sailboats.|
LOW DRAG: Under sail the Max-Prop will increase sailing speed by about 15%, the largest difference being noticed when sailing in light airs. When sailing with a fixed propeller the vessel has to overcome the fixed blade drag, installing a Max-Prop maximizes sailing performance.
RELIABILITY: Max-Prop uses a “differential” type design so all blades open in unison in forward or reverse. The extraordinary reliability of the Max-Prop has made it an overwhelming choice for long range cruisers.
GREAT REVERSE: The Max-Prop provides 80% greater reverse power than a comparable fixed blade propeller. In reverse the blades rotate 180° in 3/4 turn of the shaft giving the Max-Prop the same efficiency in reverse as in forward.
ADJUSTABILITY: The pitch is adjustable on all Max-Props. This allows you to optimize the propeller pitch to the engine to achieve maximum efficiency.

|The pitch on a Max-Prop changes according to the diameter of the propeller and the blades rotation angle.the table below shows the pitches in millimeters corresponding to the degree of blades angle for a given propeller diameter.|
Diameter and pitch must be calculated as if Max-Prop were a normal fixed propeller. Max-Prop offers the great advantage of pitch adjustability in order to optimise the performance of the propeller. Reducing the blade angle αf the propeller does not reach the desired RPM; increasing the blade angle α if, on the contrary, the engine exceeds the desired RPM. A two degrees change in blade angle will change the engine RPM by about 15%, at the same boat speed. The adjustment of angle α and therefore pitch, is done when the propeller is assembled on the shaft. To obtain the different angles you have to follow the assembly instruction.
