If you mean a boat propeller with six blades, none of the listed products has six blades: each is a three-blade design. If you mean a propeller with a 6-inch pitch, several options below match, including models for Yamaha, Mercury, Tohatsu, and Suzuki outboards. Check your engine’s make, horsepower, spline count, and original propeller part number before choosing.
| Product | Listed size | Best suited for |
|---|---|---|
| SouthMarine | 7 1/4 x 6 inches; 9 splines | Yamaha 2.5–5 HP applications |
| AQUAMOVE | 7.8 x 6 inches; 12 splines | Compatible Mercury or Tohatsu 4–6 HP engines |
| Qiclear | 9 x 9 inches; 8 splines | Listed Mercury outboard applications |
| SUNGZE | 8 1/2 x 8 1/2 inches; 7 splines | Yamaha 6–8 HP engines |
| PETUSI | 7 1/2 x 6 inches; 10 splines | Suzuki 4–6 HP engines |
SouthMarine Yamaha 7 1/4 x 6 Propeller
This SouthMarine propeller is a three-blade model measuring 7 1/4 inches in diameter and 6 inches in pitch. Its listed specifications include a nine-spline hub, and the product name identifies Yamaha 2.5–5 HP outboards.
Best for: Buyers looking for a 6-inch-pitch replacement for a compatible small Yamaha outboard. It is included because its pitch and stated engine range align with that use. Check before buying: The listing’s 9-spline count must match the engine; this is not a six-blade propeller.
AQUAMOVE 7.8 x 6 Propeller
AQUAMOVE lists a 7.8-inch diameter, 6-inch pitch, three blades, 12-tooth spline, and right-hand rotation. The aluminum propeller is described as fitting certain Mercury and Tohatsu 4–6 HP outboard engines. Hardware kits are included, and the listing describes its construction as corrosion-resistant.
Best for: Owners whose Mercury or Tohatsu engine matches the listed horsepower and 12-spline configuration. The stated pitch makes it relevant to searches for a 6-inch-pitch propeller. Check before buying: Confirm the exact engine fit and rotation; the product is not a six-blade design.
Qiclear 9 x 9 Mercury Propeller
This Qiclear model is a three-blade aluminum propeller with a 9-inch diameter, 9-inch pitch, eight-spline hub, and right-hand rotation. The listing names Mercury outboard applications and reference number 48-828156A12, while its product title specifies Mercury 9.9–15 HP.
Best for: Buyers replacing a propeller on an engine that matches the listed reference number and hub details. It offers a comparison option for Mercury owners, but it is not a 6-inch-pitch model. Check before buying: The listing gives a broader horsepower range in its features than in its title, so verify the OEM number and engine fit.
SUNGZE Yamaha 8 1/2 x 8 1/2 Propeller
SUNGZE specifies an 8 1/2-inch diameter and 8 1/2-inch pitch, with three blades and seven spline teeth. The listing identifies Yamaha 6–8 HP outboards and part number 6G1-45941-00-EL.
Best for: Yamaha owners seeking a propeller that matches the stated dimensions, spline count, and part number. It provides a model-specific alternative to the six-inch-pitch options. Check before buying: Its pitch is 8 1/2 inches, not 6 inches; confirm the OEM part number before ordering.
PETUSI Suzuki 7 1/2 x 6 Propeller
This PETUSI propeller has a 7 1/2-inch diameter, 6-inch pitch, three blades, right-hand rotation, and a 10-tooth spline. Its listed application is Suzuki DF4, DF5, and DF6 outboards, as well as compatible 4–6 HP engines.
Best for: Suzuki owners who need the listed size and 10-spline configuration. It is one of the most directly relevant choices for a 6-inch-pitch search. Check before buying: Verify the engine model and spline fit; it has three blades, not six.
Buying Guide: How to Choose an Outboard Propeller
Do you mean six blades or six-inch pitch?
Blade count and pitch describe different things. Blade count is the number of blades on the propeller; pitch is the theoretical distance the propeller advances in one rotation through a solid medium. All five options here have three blades. SouthMarine, AQUAMOVE, and PETUSI list a 6-inch pitch.
Which measurements should you match?
Match the replacement to your engine’s requirements rather than choosing by pitch alone. Compare diameter, pitch, spline or tooth count, rotation direction, horsepower range, and any OEM part number. A mismatch in hub or spline details can prevent correct installation.
- Engine make and model: Check the specific outboard identification and the product’s stated applications.
- Spline count: The listed options range from seven to 12 splines; do not assume they are interchangeable.
- Pitch and diameter: Use the dimensions recommended for your engine and operating needs.
- Rotation: Confirm right-hand or other required rotation where specified.
When should you verify fitment?
Check the original propeller markings, owner’s manual, or engine manufacturer’s parts information before ordering. Product listings can state different horsepower ranges in the title and features, as seen with the Qiclear option. If the existing propeller’s specifications or part number are unclear, confirm them with a qualified marine service professional.
Frequently Asked Questions
Are any of these propellers six-blade models?
No. Each product listed here is described as a three-blade propeller.
Which listed propellers have a 6-inch pitch?
SouthMarine, AQUAMOVE, and PETUSI list a 6-inch pitch. Their engine applications and spline counts differ.
Can I choose a propeller based only on horsepower?
No. Confirm the engine model, diameter, pitch, spline count, rotation, and applicable part number as well as horsepower.
Does a 6-inch pitch mean the propeller is six inches wide?
No. Pitch is a separate propeller measurement; diameter describes the span across the rotating blades.
What if I specifically need six blades?
These products do not meet that requirement. Look for a listing that explicitly identifies a six-blade design and verify that it is approved for your engine.
