Why Choose a 4-Blade Aluminum Propeller?
Compared to 3-blade designs, the 4-blade Amita 4 Mercury propeller delivers superior hole shot performance and smoother operation at cruising speeds. It’s especially beneficial for heavier boats or those pulling loads like water skiers or fishing gear. The additional blade provides increased surface area, improving acceleration and mid-range control.
Aluminum propellers like the Amita 4 are also more budget-friendly than stainless-steel versions while still offering impressive strength and resistance to saltwater corrosion. This makes them a top choice for recreational boaters and professionals alike.
Maintenance Tips
Maintaining your Amita 4 Mercury Propeller ensures optimal performance and longevity. Here are some key maintenance tips:
- Inspect regularly: Check for nicks, dents, or bends on the blades after every trip.
- Clean thoroughly: Rinse with freshwater after saltwater use to prevent corrosion buildup.
- Apply grease: Lubricate the propeller shaft every 20–30 hours of use or monthly.
- Check torque: Ensure the propeller nut is secure but not overtightened.
- Store safely: During off-season, remove and store your propeller in a dry place to avoid rust and damage.
These tips help extend your propeller’s life and protect your engine’s lower unit.

Detailed FAQ Section
What boats are compatible with the Amita 4 Mercury 11.8 x 9 propeller?
This propeller is designed for Mercury outboard engines, typically in the 25HP–90HP range. It fits a variety of small to medium-sized fishing boats, pontoons, and skiffs. Compatibility may vary depending on the shaft size and hub kit, so check your engine’s manual or consult a marine parts expert before purchasing.
How often should I replace my propeller?
With proper care, an Amita 4 Mercury propeller can last 3–5 years or more. Replace it sooner if you notice significant damage such as blade deformation, cracks, or excessive corrosion. Performance drops, strange noises, or engine strain are also signs it’s time for a new prop.
What’s the difference between 3-blade and 4-blade propellers?
3-blade propellers are typically faster at top speeds and good for lighter boats, while 4-blade propellers like the Amita 4 provide better grip, quicker hole shots, and smoother cruising, especially with heavier loads or choppy conditions. They also offer more control when docking or towing.
How do I know if I need a right-hand rotation propeller?
