Aluminum Propellers for 9.9-20HP Suziki Outboard Boat Motor

Choosing the right aluminum propeller for your 9.9-20HP outboard motor can make all the difference in performance, fuel efficiency, and maneuverability. Although these propellers fit Suziki engines in the 9.9-20HP range, they are also suitable for certain Yamaha and Mercury motors. We are not affiliated with Suziki, Yamaha, or Mercury, but our aluminum props are crafted to align with their compatibility standards. Below, you’ll find a comprehensive table that details key specifications such as OEM references, blade count, diameter, pitch, and rotation type. This information will help you match the perfect propeller to your outboard setup.

Propeller Specifications

The following table highlights propellers compatible with 9.9-20HP outboard motors featuring a 2-1/2" gearcase, eight-spline tooth, and thru-hub exhaust. These propellers can accommodate various two-stroke and four-stroke applications, including models from 1984 to newer releases in the 2000s. Always verify the OEM number and measurements before making a final decision.

In-Depth Look at Each Specification

1. OEM Number
   Each OEM reference helps identify the intended engine match. Even though these numbers often align with Yamaha or Mercury listings, our aluminum props are independently produced. Double-checking your motor’s model and shaft specifications ensures a hassle-free fit.

2. Blade Count (B)
   Propellers in this range typically come with either three or four blades. Three-blade designs usually deliver a balanced combination of speed and fuel efficiency, whereas four-blade props enhance low-speed handling and help maintain steadier thrust in choppy waters.

3. Diameter (D)
   Measured in inches, diameter influences acceleration and overall performance. Larger diameters can provide more thrust, which is especially beneficial when hauling heavier loads. Most of the listed propellers measure 9.25 inches in diameter, but a few variations reach up to 10 or even 11.75 inches.

4. Pitch (P)
   Pitch refers to the theoretical distance a propeller travels forward in one full rotation. A lower pitch supports quick acceleration and better low-speed maneuvering. On the other hand, higher pitch values improve top-end speed. In this list, pitches range from 5 to 12, accommodating diverse boating requirements—from fishing boats to small recreational vessels.

5. Rotation (R)
   The rotation type is typically right-hand (R) or left-hand (L), although most small outboards use a right-hand rotation. A few props here are noted with “J,” often used as a designator for right-hand rotation in certain OEM contexts. Always confirm that the rotation aligns with your engine’s gear setup.

Why the Right Propeller Matters

• Enhanced Efficiency
  Choosing an optimal pitch and diameter can reduce engine strain, potentially improving fuel consumption.
• Smooth Handling
  A well-fitted propeller ensures responsive steering and easier maneuverability in tight spots.
• Prolonged Engine Life
  Properly matched props minimize vibration and reduce wear on internal components.
• Versatile Performance
  Whether you prioritize speed or torque, having the right blade count and dimensions makes all the difference on the water.
