Qiclear Aluminum 9 x 9 Boat Propeller for Mercury 9.9–15HP (48-828156A12) 8-Spline, Right Rotation

Qiclear 9 x 9 48-828156A12 is a high‑quality, three‑blade aluminum outboard propeller designed to replace OEM units on Mercury 9.9–15HP engines for reliable speed, acceleration and efficiency.

This replacement propeller is built to the same reference specification used on many small outboard motors: 9" diameter by 9" pitch, 8‑spline hub and a 2.5" gearcase fit. Finished in durable black paint and crafted from high‑grade aluminum, it balances corrosion resistance and strength while keeping weight low. It installs like an OEM unit and is intended for right‑rotation applications on compatible Mercury engines.

Will this propeller fit my Mercury outboard?

If your engine lists a compatible reference or matches the dimensions, this prop fits directly. It is designed for 6/8/9.9/10/15HP outboards that accept an 8‑spline hub and a 2.5" gearcase. Always compare part numbers and physical measurements before purchase.

• Reference number: 48‑828156A12 (OEM equivalent)
• Hub spline: 8 teeth for standard small outboards
• Gearcase fit: 2.5" diameter mounting surface
• Rotation: right‑hand (clockwise when viewed from rear)

How does the 9 x 9 size affect performance?

Diameter and pitch influence top speed, hole‑shot acceleration, and engine load. A 9" diameter with a 9" pitch is a balanced choice for small craft, offering good midrange acceleration without overstressing a 9.9–15HP motor. It helps maintain efficient rpm band for common recreational boating tasks.

• 9" diameter: compact, suited to small hulls and skiffs
• 9" pitch: moderate top speed with practical acceleration
• 3 blades: stable thrust and predictable handling
• Aluminum build: lightweight for responsive throttle feel

What materials and construction features matter?

This Qiclear propeller uses high‑quality aluminum with a protective paint finish to resist corrosion and abrasion in fresh and saltwater. Precision casting and finishing ensure the blades are balanced to reduce vibration and wear on the lower unit. Solid construction supports consistent rpm and helps preserve fuel efficiency.

• Material: high‑grade aluminum for low weight and stiffness
• Finish: black paint for added surface protection
• Blade count: three blades for smooth thrust and control
• Quality control: inspected for balance and fit before shipping

How easy is installation and maintenance?

Installation follows the same steps as swapping an OEM prop: remove the retaining nut, slide off the old prop, fit the hub and new prop, then secure with the correct washer and nut. Routine checks for dings, bent blades or corrosion will help maintain performance and extend service life.

• Installation: direct fit for compatible 8‑spline hubs
• Fastening: uses standard prop nut and washer arrangement
• Maintenance tips: inspect blades and hub after strikes
• Service support: seller offers 24‑hour response for questions

Who is this for: Boaters who need a cost‑effective, OEM‑style replacement for Mercury small outboards, anglers and recreational skiff owners looking for dependable acceleration and consistent cruising RPMs. Choose this propeller if your engine requires an 8‑spline, 2.5" gearcase fit and you need a right‑rotation, 3‑blade aluminum prop for everyday use.
