A strong outboard propeller matches your engine’s make, horsepower range, spline, and pitch; the right choice here depends on those details more than on a broad “fits outboards” label. This roundup compares ten aluminum and stainless-steel options for Mercury, Yamaha, BRP Johnson/Evinrude, and Hangkai engines, from a 3.5-hp replacement to models listed for engines as large as 140 hp. The Qiclear Flo-Torq Propeller leads for its broad stated Mercury horsepower range and included hub kit, while the Mercury Spitfire stands out for its four-blade design and stated acceleration advantage.
Before ordering, verify the engine’s exact model and gearcase, along with the propeller’s diameter, pitch, spline count, and rotation. Listed fit ranges and dimensions are useful starting points, not a substitute for checking the application.
The Qiclear Flo-Torq Propeller is the best overall choice in this group for buyers whose Mercury outboard falls within its stated 40–140-hp range. It measures 13 1/4 inches by 17 inches and includes a 835257Q1 Flo-Torq II hub kit, giving buyers both a clear size and a listed included component. Confirm the exact engine application before purchasing: the listing’s broad horsepower range does not establish compatibility with every Mercury model or gearcase.

7. Qiclear Mercury 13 1/4×17 Propeller

- Weight: 6 lb
Best for: Mercury 17-pitch aluminum option.
Why it ranks #7: Its 13 1/4-by-17-inch aluminum design is listed for Mercury 60–125-hp engines, though this listing does not specify an included hub kit.

Best for: Small Mercury saltwater replacement.
Why it ranks #8: This aluminum 10 3/8-by-13 propeller has a 10-spline specification and is listed for Mercury 9.9–25-hp engines.
A stated saltwater use recommendation distinguishes this VIF aluminum propeller for Mercury 9.9–25 hp outboards. Its 10-spline connection and 10 3/8 x 13 dimensions provide specific fit and size details, helping buyers narrow their search to a smaller-engine replacement rather than a general-purpose propeller listing.

- Material: Aluminum
- Package Dimensions: 12.4 x 12.13 x 6.14 in

10. MOPFOL Hangkai 3.5HP Propeller
- Material: Aluminum
- Weight: 10.56 oz
Best for: Hangkai 3.5 hp direct replacement.
Why it ranks #10: This lightweight aluminum three-blade replacement is specifically designed for Hangkai 3.5-hp motors, making its stated application much narrower than the other options.
Direct replacement compatibility with Hangkai 3.5 hp outboards is the defining advantage of this lightweight, three-blade MOPFOL propeller. Its CNC-machined aluminum construction and stated easy installation support owners replacing an old or broken propeller without modifications, while the compact 10.56-ounce listed weight is relevant for carrying and handling.
The stated Hangkai 3.5 hp fit and direct-replacement description make this a narrowly targeted option for owners of that motor. CNC-machined aluminum construction is presented as durable in marine environments, and the three-blade design is described as supporting thrust efficiency, fuel economy, smooth acceleration, and stable operation. The lightweight, portable description and easy-installation claim also suit a straightforward replacement workflow. The listing does not give a pitch measurement, so buyers have fewer dimensional details to compare.
- Specifically listed for Hangkai 3.5 hp
- Direct replacement without modifications stated
- CNC-machined aluminum construction

View on AmazonWhy a stated horsepower range is not enough
A stated horsepower range alone cannot confirm that a propeller fits your outboard. Listings here also distinguish spline counts, gearcase dimensions, rotation, and exact engine applications: for example, the VQPROPs Yamaha Propeller specifies 13 splines and a 3.5-inch gearcase, while the OULEME Mercury 13-Spline Propeller specifies 13-tooth splines and RH rotation. The VIF Mercury 9.9-25 Propeller instead lists 10 splines.
Those differences are not interchangeable simply because horsepower ranges overlap. Check the engine’s full model information and the existing propeller’s markings against the replacement listing; confirm the gearcase and rotation as well as horsepower.
A mismatch can prevent proper installation or make the propeller unsuitable for the application. Where a listing provides only a broad range, treat it as a screening clue and verify the exact fit before ordering.
Pitch and blade count involve different trade-offs
Pitch and blade count describe different aspects of a propeller, so compare both rather than treating one number as a complete performance forecast. The Qiclear Flo-Torq Propeller and Qiclear Mercury 13 1/4×17 Propeller list 17-inch pitch, while the VIF Mercury 30-70 Propeller offers several listed choices from 9p to 15p. This makes the VIF’s range useful to buyers who need to match a particular pitch, but the listing does not establish which pitch suits a particular boat and engine setup.
Blade count also varies: the Mercury Spitfire Propeller has four blades, and its listing states 16–25% faster acceleration than a comparable three-blade prop. That is a product claim, not a guarantee for every boat.
Decide what your setup requires, confirm the maker’s application guidance, and avoid assuming that a pitch or blade-count change will improve every measure of performance.
How to Choose an Outboard Propeller
Engine fit and spline count
Look first for an exact engine and gearcase match, not just a horsepower range. These products span Mercury 9.9–25 hp, Mercury 30–70 hp, Yamaha 25–60 hp, BRP Johnson Evinrude 40–75 hp, and Mercury listings reaching 140 hp. Spline counts also vary: the VIF Mercury 9.9-25 Propeller specifies 10 splines, while the VIF Mercury 30-70 Propeller, VQPROPs Yamaha Propeller, and JSPROP BRP 12 1/4×15 Propeller list 13.
The CAPTAIN Yamaha Stainless Propeller specifies Buyers replacing an existing prop should match the original fit details; buyers with an older or less common engine should prioritize an exact application listing over a wider advertised horsepower span.
Diameter and pitch
Choose a diameter and pitch that match your engine application and the propeller you are replacing. Listed examples include 10 7/8-by-11 inches for the OULEME Mercury 13-Spline Propeller, 12 1/4-by-15 inches for the JSPROP BRP 12 1/4×15 Propeller, and 13 1/4-by-17 inches for both Qiclear 17-inch options. The VIF Mercury 30-70 Propeller lists several pitches—9p, 10p, 11p, 13p, 14p, and 15p—rather than just one.
That choice can help buyers seeking a particular replacement pitch, while a fixed-size listing is simpler when the correct size is already known. Do not infer ideal pitch from horsepower alone; confirm the application for your boat and engine.
Material and blade configuration
Compare material and blade count against your intended replacement, while treating performance statements as specific to the listing. Most options here are aluminum, including the VIF, Qiclear, VQPROPs, OULEME, and JSPROP propellers. The CAPTAIN Yamaha Stainless Propeller uses 17-4PH stainless steel, and the Mercury Spitfire Propeller is a four-blade aluminum option.
The other products are presented as three-blade designs or, in several cases, do not state blade count in the supplied specifications. Buyers who need to match a standard aluminum replacement have several choices; buyers specifically seeking stainless steel or four blades can narrow the list quickly.
Verify the exact application before switching material or blade configuration.
Which Outboard Propeller Should You Choose?
Choose the Qiclear Flo-Torq Propeller if your Mercury application matches its stated 40–140-hp range and you want the included Flo-Torq II hub kit. For a Mercury four-blade option, consider the Mercury Spitfire Propeller, checking its listed engine applications and 14-by-19-inch dimensions. Yamaha owners seeking stainless steel should compare their engine details with the CAPTAIN Yamaha Stainless Propeller’s 15-spline, 13.25-by-17-inch specification; those needing an aluminum Yamaha option can check the VQPROPs Yamaha Propeller’s 25–60-hp fit.
For Mercury 25–75 hp, the OULEME Mercury 13-Spline Propeller lists a 10 7/8-by-11-inch size. The VIF Mercury 9.9-25 Propeller, JSPROP BRP 12 1/4×15 Propeller, and MOPFOL Hangkai 3.5HP Propeller serve narrower engine-specific applications.

Frequently Asked Questions
How do I confirm which propeller fits my outboard’s exact model and gearcase?
Check your outboard’s exact model and gearcase against the propeller listing and the manufacturer’s application information. Also verify spline count, diameter, pitch, and rotation where listed; a broad horsepower range alone does not confirm fit. If details are unclear, ask the manufacturer or a qualified dealer to confirm before ordering.
How does changing propeller pitch affect engine performance and operation?
Pitch is the distance a propeller is designed to advance in one rotation, and changing it can alter engine load and how the boat accelerates or runs. The right choice depends on the outboard and boat. Follow the engine maker’s guidance and avoid choosing pitch by number alone without checking the application.
When should I choose a three-blade propeller instead of a four-blade propeller?
Choose based on the needs of your boat and the propeller approved for your outboard, rather than blade count alone. This group includes a four-blade Mercury option, but the supplied details do not establish a universal performance advantage for either design. Confirm exact engine application, dimensions, pitch, and rotation before comparing options.
What information should I check beyond horsepower before ordering?
Check the exact engine model, gearcase, spline count, propeller dimensions, and rotation. The listings show why those details matter: options specify different spline counts, sizes, pitch, and applications. A stated horsepower range is useful for narrowing choices, but it does not prove compatibility with every engine in that range.
Which option is the leading choice for a compatible Mercury outboard?
The Qiclear Flo-Torq Propeller is the editorial pick for a Mercury outboard within its stated 40–140-hp range. It measures 13 1/4 by 17 inches and includes a 835257Q1 Flo-Torq II hub kit. Confirm the exact engine model and gearcase, since the horsepower range alone does not establish fit.
Final Words
Start by matching the propeller to your outboard’s exact model and gearcase, then verify spline count, dimensions, pitch, and rotation. For a compatible Mercury within the stated 40–140-hp range, the Qiclear Flo-Torq Propeller is the group’s best overall choice and includes a Flo-Torq II hub kit. Consider the listed alternatives for their specific applications, but treat horsepower ranges as a starting point—not proof of fit.
