Qiclear aluminum outboard propeller 14.25x21 RH 15-spline — Flo-Torq hub kit, heat-treated blades

Qiclear’s 14.25" diameter x 21" pitch aluminum outboard propeller (OEM 48-832832A45) is a right-hand, 15-spline replacement designed to restore performance for Mercury/Mariner 135–300 HP and compatible sterndrive models.

Designed as a direct-fit aftermarket option, this Qiclear propeller combines vacuum-cast aluminum, a heat-treated blade structure, and a five-layer surface finish to provide long-lasting service and reliable boat control. It ships with Flo-Torq II style hub upgrade kits (835257Q1) for straightforward installation and improved vibration damping. The prop’s dimensions, spline count, and rotation match common Mercury OEM specs so it fits Mercruiser, Bravo One, Alpha, and outboard engines in the specified horsepower range.

Will this propeller fit my Mercury or Mariner engine?

Compatibility hinges on three details: diameter and pitch, spline count, and rotation. This Qiclear model matches the OEM part number 48-832832A45 and is built for 15-spline, right-hand rotation installations on many Mercury/Mariner outboards and certain Mercruiser sterndrive applications.

• Fits Mercury/Mariner 135–300 HP outboards when OEM specs match.
• Compatible with Mercruiser sterndrives: Bravo One, Alpha, and similar models.
• 15-spline hub and right-hand (RH) rotation — confirm your shaft specs before ordering.
• Included Flo-Torq II style hub kits simplify retrofit and reduce vibration.

How does the Qiclear 14.25 x 21 prop affect speed and handling?

The 14.25" diameter and 21" pitch provide a balance between top speed and mid-range acceleration for boats matched to this size. The blade geometry and heat-treated aluminum aim to maintain RPM under load while improving throttle response and fuel efficiency compared with worn or incorrect props.

• 21" pitch favors higher top-end speed while preserving reasonable acceleration.
• Heat-treated blades resist deformation under load for consistent performance.
• Five-layer surface finish minimizes drag and helps maintain RPM stability.
• Vacuum casting produces consistent blade thickness and balance.

What’s included and how easy is installation?

The propeller ships complete with upgrade hub kits modeled after the 835257Q1 Flo-Torq II style, streamlining replacement of worn hubs and improving shock absorption. Installation is straightforward for anyone familiar with prop swaps; basic tools and standard torque specs are all that’s required.

• Propeller (14.25" x 21", RH, 15-spline) plus Flo-Torq II style hub kits included.
• Sold as pictured — ready to install after removing the old prop and hub pieces.
• No special machining or modification typically required when matched to OEM specs.
• Manufacturer support available for fitment questions and troubleshooting.

How durable is the material and finish?

Qiclear uses vacuum-cast aluminum with a five-layer surface treatment and heat-treated blade edges for improved toughness. Those features reduce the chance of cracking or premature wear while helping resist corrosion in normal freshwater and light saltwater use when properly rinsed and maintained.

• Vacuum casting reduces internal defects and improves consistency.
• Heat-treated paddles increase resilience to impact and flex fatigue.
• Multi-layer surface processing helps prevent corrosion and abrasion.
• Quality control aims to preserve performance without sacrificing durability.

Who this propeller is for: Boaters who need a cost-effective, OEM-spec replacement for Mercury/Mariner 135–300 HP outboards or compatible Mercruiser sterndrive installations. It suits skippers seeking improved top-end speed, consistent RPM under load, and an easy swap using Flo-Torq II style hub components. Verify your shaft spline count, rotation direction, and OEM part number before ordering to ensure proper fitment.
