Propeller Basics: 3x15 1/2x17-LX
This information is critical to determining the correct propeller for your application:
1. 3 Blades
A 3-blade propeller usually offer s top speed performance.
2. Diameter:
Diameter is the distance across a circle encompassing all of the propeller blades.
(see Original Equipment Considerations item below)
3. Pitch:
Pitch is the theoretical distance a propeller will move through the water of each revolution.
4. Right hand or left hand Rotation
In most cases, right hand propellers are used for single engine application and one left hand propellers are used for twin engine applications to achieve better steering control.
5. Cupped Blades:
This is a technique used to enhance the performance of propellers under certain conditions. A cupped propeller will exhibit very high efficiency at high speeds as well as minimize cavitation under heavy loads.
6. Rake:
Rake is special design feature. Positive rake benefits from normal bow lift to permit the use of a larger diameter propeller, while negative rake can provide extra blade strength for use in very high speed applications.

The use of suitable propeller for your boat is as much important as its engine power. Professionally selected engine and propeller ensure smooth movement of your boat, reduce fuel consumption, increase the durability of engine and provide better speed. At the same time, your boat moves more safe and reliable. Marine propellers control the boat movement just like proper tires influence on the driving of your auto.
When choosing the propeller for your boat, you should consider the following characteristics:
Diameter of propeller is described as a circle, created by the blade rotation. Small-sized boats deal better with propellers of big diameter. Boats of high performance use propellers of small diameter. Diameter rate depends on engine and lower unit rotation rate.
Pitch is the distance that propeller passes per one rotation. For developing high speed of your boat or yacht, propellers with big pitch should be used.
Our online store is glad to offer you marine propellers of well-trusted and high quality Mercury brand. Left and right rotation-type propellers are available.
