They typically yield a slightly higher top end speed than 4 blades. They are available in wide size ranges and cost less than 4 blades. In general, 3 blade props are the most common. This article confines itself to the discussion of 3 and 4 blade props as these are the most common in the real world. The purpose of this article is not to explain propeller theory or hydrodynamics, but rather to point out the various options in the market place and set some common rules of thumb. This just makes it that much harder to make a decision and choose the right prop. Often times, there may be 6 or 8 different props that seem to run about the same, with differences so subtle that any of them could be considered satisfactory by most standards. Acceleration may be compromised for top speed and fuel economy, and visa versa. There is no such thing as the best or ideal prop for all applications of a similar nature. Top Speed, Cruising Speed, Hole Shot, Load Carrying, Slow-Speed Handling, Slow Trolling, Fast Trolling? Two identical boats with identical engines could be propped quite differently, depending on the usage, water conditions, and load.

The two most important things to remember in choosing a propeller are that it meets your individual needs for your individual application and that it allows the engine(s) to run within the specified RPM range at full throttle. Propellers with higher rake angles and some with more surface area have been developed to maximize the power delivery of the 4-stroke torque curve. Propeller manufacturers have been busy developing new 3-blade and 4-blade products and size ranges of stainless steel propellers to meet a growing number of hull types and horsepower ranges, especially for 4-stroke engines.įour-stroke engines are designed to run at very specific RPMs, so pitch sizes have become available in 1 inch increments and new designs have appeared, each more tailored to a specific hull type and application. easier because the number of choices has doubled, and harder, for the same reason. Recent advantages in outboard technology have made choosing the correct propeller for your boat both easier and more difficult. Prop installation, inspection and boat operation all need to be done in a safe and responsible manner.Choosing the Right Propeller_By Neil Mullen.

When in doubt, dealer assistance is suggested. This is important in determining a suitable propeller pitch.

Wide open throttle RPM, with boat on the water in forward gear under normal loading conditions, should fall within the range that is recommended by the engine manufacturer and not exceed the recommended maximum.

Engine manufacturer recommends greasing the propeller shaft every 12 months.

Make sure all propeller hardware is installed correctly.

A new propeller's hub and blades must be checked for sufficient lower unit and trim tab clearances before use.
