Information: How to check how correctly the propeller is matched to the boat?
It is necessary to measure the speed in "full throttle" with maximum and minimum load. RPM must be within the manufacturer's recommended range. If the motor "does not turn" the speed - set the screw with a smaller pitch, if the motor "twists", that is, the speed is exceeded - then the step needs to be increased.
Important parameters:
- Three or four blade propeller
A 3-blade propeller has less drag and a higher efficiency, but 3-blade propellers cavitation earlier. A 4-bladed propeller with the same diameter allows you to process more power and reduce vibration.
Also, the 4-bladed propeller reduces time to planing and can even save fuel when cruising. However, at low power, the maximum achievable speed of a vessel with a 4-blade propeller is less than with a 3-blade propeller of the same diameter and pitch.
- Diameter
The propeller diameter is the diameter of the circle enclosing all the propeller blades. Usually, the lower the propeller shaft speed, the larger the diameter should be.
Proper selection of the propeller diameter is very important for the interaction between the propeller and the vessel. As a rule, for relatively low-speed vessels, a propeller with a larger diameter is used, for high-speed vessels, with a smaller one.
- Step
The propeller pitch is its most important technical characteristic. The pitch of the screw corresponds to the theoretical distance that the screw will move in one complete revolution in a non-deformable medium.
Example:
A propeller with a pitch of 500 mm (20 inches) with each complete revolution would have to move the vessel 0.5 m in the absence of slip (that is, if the propeller was screwed into the water, as in a solid medium). But since the propeller pushes the water back, the true displacement of the ship will be less.
