Review MERCURY 21p 3-blade Stainless Alpha Bravo Prop Propeller fits SILVERADO

The 5056-21 Silverado 13-3/4" 4-blade Alpha Bravo Propeller from Mercury is a high-quality, reliable propeller designed to enhance the performance of your outboard engine. This propeller features a 13-3/4" diameter, making it an excellent choice for medium-sized boats and outboard engines.

The Alpha Bravo propeller is a 4-blade design, which provides a balance between efficiency and thrust. The 4 blades allow for a smooth and stable ride, while also delivering strong acceleration and top-end speed. The 4-blade design also reduces cavitation, which can occur in 3-blade propellers at high RPMs, resulting in better fuel efficiency and longer engine life.

The 5056-21 Silverado propeller is made of aluminum alloy, which is lightweight and durable. The aluminum alloy construction reduces the overall weight of the propeller, which in turn reduces the load on the engine and improves fuel efficiency. The aluminum alloy is also resistant to corrosion, ensuring that the propeller will last for many seasons of use.

The propeller blade design is unique to the Alpha Bravo series, with a scalloped leading edge that reduces drag and increases the propeller's efficiency. The scalloped leading edge also helps to reduce the risk of propeller damage in rough water or when hitting obstacles. The blades are also tapered, which helps to reduce cavitation and improve the propeller's performance at both low and high RPMs.

The 5056-21 Silverado propeller is designed for use with Mercury outboard engines, and is specifically engineered for use with a 21-pitch. The pitch of the propeller is an important factor in determining the propeller's performance, and the 21-pitch is an excellent choice for medium-sized boats and outboard engines. The 21-pitch allows for a balance between speed and maneuverability, providing a smooth and responsive ride.

Overall, the 5056-21 Silverado 13-3/4" 4-blade Alpha Bravo Propeller from Mercury is a high-quality, reliable propeller that is designed to enhance the performance of your outboard engine. Its lightweight aluminum alloy construction, unique blade design, and 21-pitch pitch make it an excellent choice for medium-sized boats and outboard engines.

1. Efficiency: The 3-blade design of the propeller allows for increased efficiency, resulting in better fuel economy and faster acceleration.

2. Durability: The Alpha Bravo propeller is made from high-quality materials, such as aluminum alloy, which makes it resistant to corrosion and damage from impact.

3. Versatility: The 21p pitch of the propeller allows for a wide range of applications, from cruising to watersports.

4. Warranty: Mercury offers a limited warranty on their propellers, providing peace of mind in case of any defects.

1. Price: The Alpha Bravo propeller is more expensive than some other options on the market.

2. Limited Availability: The Alpha Bravo propeller may not be as widely available as other propeller brands, which could make it more difficult to find in certain locations.

3. Potential for Noise: The 3-blade design of the propeller may result in more noise compared to a 2-blade propeller.

The 5056-21 Silverado 13-3-4 21p 3-blade Alpha Bravo propeller for a Mercury outboard engine is a high-quality option with several benefits, including increased efficiency, durability, and versatility. However, the higher price and potential for noise may be drawbacks for some consumers. Ultimately, the decision to purchase this propeller should be based on individual needs and preferences.

If you are looking for a high-performance propeller that offers excellent efficiency and durability, the 5056-21 Silverado 13-3-4 21p 3-blade Alpha Bravo propeller is a great option. However, if budget is a concern or noise is a significant issue, you may want to consider other options that may be more affordable or quieter. It's always a good idea to do your research and consult with a professional to ensure that the propeller you choose is the best fit for your boat and outboard engine.

Details:

It turns out 21 pitch was too much and engine would not get to full rpm except in cold weather with only one person on-board. Prop is in excellent condition. No hub kit comes with it as I kept the on my 19p prop that stayed boat when sold.

I ran this prop only a few hours and see no nicks or gouges, so basically in like-new condition except for some surface tarnishing as its been my basement now several years. I bought this for a 21' seaway br210 with 240hp alpha out drive.
