Overview / What Is Amita 3 – Mercury (13 x 21″) Solas RH Propeller?
The Amita 3 Mercury propeller marine is a three‑blade aluminum propeller built by Solas for Mercury outboard motors. The designation “13 x 21” refers to a 13‑inch diameter and a 21‑inch pitch. This higher‑pitch propeller delivers more forward slip per revolution, which translates into better top speed at the cost of slightly reduced low‑end thrust.
With an RH (right‑hand) rotation design and compatibility with Mercury hubs, this propeller is ideal for boats that operate primarily at higher cruising speeds. It’s especially advantageous for performance‑minded users who want to extract more speed from engines rated in the 80HP to 150HP range without moving to stainless steel.
Key Technical Specifications

This propeller merges Solas’s precision casting with Mercury hub compatibility for plug‑and‑play installation. The 21‑inch pitch allows higher surface speed per revolution, earning it a spot among the best Amita 3 propeller options for speed‑oriented boating.
Performance Benefits of 13 x 21 Pitch
Choosing the 13 x 21 configuration offers several performance advantages. The increased pitch delivers more distance per revolution, which benefits top speed and fuel economy at cruising RPMs. Compared to a 13 x 19 propeller, the 21 pitch reduces engine RPM at a given speed, enhancing efficiency on longer trips or sustained runs.
This setup suits heavier or planing boats that need to overcome drag at higher speeds. When engine RPM remains in its optimal band, wear is reduced and fuel consumption improves—making it one of the best cost and durability options in the Amita 3 series.
How to Install the Amita 3 Mercury Propeller
Understanding how to install/use/repair the Amita 3 Mercury propeller marine correctly is essential for safe performance:
- Turn off the engine and secure the craft to prevent movement.
- Remove the cotter pin and loosen the prop nut with a proper wrench.
- Slide off the old propeller, inspecting the shaft, keyway, and hub components.
- Clean and grease the drive shaft generously with marine‑grade grease.
- Align the propeller on the splined shaft and slide it fully into place.
- Install the prop nut, torque according to Mercury specifications, and secure with a new cotter pin.
Warning: Never re‑use cotter pins or neglect shaft greasing—failure to lubricate can lead to seizure or hub damage.
Following these installation and maintenance tips ensures the propeller runs smoothly and extends its lifespan in both salt- and freshwater conditions.
Comparing 13 x 21 vs. 13 x 19 Pitch Options
When evaluating long‑term performance, the difference between a 13 x 19 and a 13 x 21 propeller is significant. The 19 pitch offers better low‑end acceleration and heavier load pull, making it ideal for fishing, towing, or slower trolling operations. In contrast, the 21 pitch sacrifices some low RPM grunt in exchange for cruising efficiency and top‑end gain.
Boaters should consider their primary use: if high speeds and fuel economy at mid‑range RPMs are priorities, the 13 x 21 is a superior choice. If acceleration or pulling power is key, the 19 might be better despite slightly reduced cruising performance.
Maintenance Tips
By following regular Amita 3 Mercury propeller marine maintenance tips, you’ll preserve performance and prevent unnecessary repairs:
- Rinse after every trip: Remove salt, sand, and marine growth with freshwater especially after saltwater use
- Inspect blades: Look carefully for nicks, cracks, bent tips, or signs of cavitation
- Balance check: Have a propeller shop evaluate blade balance periodically to avoid vibration
- Grease shaft: Clean and apply fresh marine grease at least once per boating season
- Storage care: Store in a dry location, avoid stacking heavy items on the prop
Proactive maintenance directly impacts cost and durability of the propeller. Neglect often leads to inefficient propulsion performance, increased fuel burn, or even mechanical damage.
