Choosing The Right Propeller Propeller selection is very important in the performance of the boat.
Acceleration, speed, fuel efficiency, stability and engine RPM all are affected by the propeller.
Operating requirements and conditions will also determine which design, style and pitch of the propeller your customer can choose.
The combination of boat, engine and appropriate propeller size may have already been tested by the boat manufacturer.
Your Customer may need your assistance to determine the correct propeller for their application.
Stainless Steel Propellers Suzuki Stainless Steel Propellers offer high performance and durability.
Their aggressive design enhances the overall performance of the boat and the durability of stainless steel ensures long term dependability.
Suzuki Stainless Steel propellers are also fitted with a rubber cushion hub to help absorb vibration and shock should they strike a foreign object.
Propeller Sizing When referring to propeller size, the first number is the number of blades, the second number details the diameter of the propeller, and the third number is the pitch Example: 3 x 13 x 18 = 3 blades x Diameter: 13 inches x Pitch: 18 inches.
The pitch is the most significant factor when choosing a propeller.
Diameter

Diameter is the distance across an imaginary circle that is made when a propeller rotates.
Diameter is determined during the designing process of a propeller and is usually based on engine size, gear case design, horsepower and speed.
Pitch

Pitch is the theoretical distance that a propeller corkscrews forward through the water.
In theory, an 18?(457.2mm) pitch propeller would travel 18?(457.2mm) with each complete revolution.
Lower pitches accelerate faster, but have lower top end speed.
Higher pitches have a slower acceleration, but attain higher top speeds.
An inch of pitch is generally equal to 150-200 engine RPM at wide open throttle (WOT).
If pitch increases by an inch, RPM will decrease by 150-200 RPM at WOT.
If pitch decreases by an inch, RPM will increase by 150-200 RPM at WOT.
Note during actual operation, this number will be affected by slip factors such as water conditions, boat weight, propeller style, etc.
Propeller Cup

Cup is the curve along the trailing edge of the propeller blade.
This reduces propeller slip and ventilation, allowing users to operate their engine at a higher transom mounting, and use more trim for bow lift.
Rake

Rake is the angle, in degrees, that the propeller blades are mounted to the barrel of the propeller.
Blades of a zero degree rake propeller are mounted perpendicular to the barrel .
High rake propellers have blades that angle more to the rear of the propeller.
These blades hold water longer and ventilate less at higher engine heights.
Such propellers produce higher thrust which helps lift the bow of the boat more effectively.
