Propeller Size Recommendation
In order to receive a propeller size and quote, please email/phone (both listed below) us with as much of the following information as you can.
The first 5 items are needed to calculate the propeller's diameter and pitch.
1. Boat (Make and Model) 2. Engine (Make and Model) 3. Transmission Reduction Gear Ratio 4. Displacement (Weight) 5. Water Line Length 6. Shaft Size or Sail Drive Model 7. Propeller Rotation left-hand or right-hand 8. Current Propeller Size and Type (i.e., fixed 3-blade, feathering, etc.) 9. Do you want a feathering or folding propeller? 10. Are there space restrictions like an aperture?

Understanding Propeller Diameter and Pitch
Selecting the right propeller is crucial for optimal boat performance and efficiency. Key factors such as hull type, engine reduction ratio, and your performance goals—racing versus cruising—play a significant role in determining the diameter and pitch of your sailboat propeller. The sailboat propeller diameter pitch calculator is an invaluable tool for assessing these dimensions, ensuring you achieve the best possible balance between speed and power.
Hull Type and Performance Goals
The shape and design of your hull influence hydrodynamic efficiency and can alter the ideal propeller characteristics. For racing hulls, a higher pitch may be preferred to maximize speed, while cruising hulls may benefit from a lower pitch, enhancing thrust and control. Understanding your specific hull design allows us to recommend the optimal propeller adjustments tailored to your performance expectations.
Engine Reduction Ratio and Its Impact
The engine’s reduction ratio also significantly affects propeller choice. A lower reduction ratio typically means the engine provides more torque, which can support a larger diameter and lower pitch. Conversely, a higher reduction ratio often necessitates a smaller diameter and higher pitch to maintain optimal RPMs. Through our sailboat propeller diameter pitch calculator, we can ensure you make an informed selection based on your unique engine specifications.
Premium Features for Enhanced Performance
In addition to our MARTEC folding and feathering propellers, we offer specialized Slipstream propeller polyurethane bump stops to enhance overall prop performance and lifespan. These bump stops absorb shock and reduce vibration, contributing to a smoother experience while protecting your propeller and drivetrain.
