Overview / What Is Amita 3 – Tohatsu/Nissan (14.3 x 21″) Solas LH Propeller?
The Amita 3 propeller is part of the Solas aluminum propeller range and is known for its outstanding reliability and economic price point. Designed specifically for Tohatsu and Nissan outboard engines, the 14.3 x 21″ model (1512-143-21) is a left-hand rotating propeller, ideal for twin-engine boats or specific performance needs. The 3-blade design offers high-performance thrust, minimal vibration, and precise handling.
This aluminum propeller is corrosion-resistant and highly durable, making it ideal for saltwater and freshwater environments. It’s also designed with an exclusive squeeze cast process that enhances tensile strength and creates a smoother finish compared to traditional die-cast propellers.
Why Choose a Left-Hand Rotation Propeller?
Boaters often ask why or when to use a left-hand (LH) rotation propeller like the Amita 3 1512-143-21. LH propellers are especially beneficial for dual engine setups where one engine uses RH rotation and the other LH to counterbalance torque and improve stability. This rotation reduces prop walk, increases efficiency, and enhances steering control.
In certain single-engine boats, LH props may also be used to suit specific design configurations. Always consult your engine manufacturer to determine the optimal rotation for your vessel. The Amita 3 LH propeller offers outstanding torque response and smoother transitions when switching gears.

- Material: High-quality aluminum with corrosion-resistant coating
- Size: 14.3″ diameter x 21″ pitch
- Rotation: Left-Hand (LH)
- Blade Count: 3 blades for efficient thrust
- OEM Replacement: Matches factory specs for Tohatsu/Nissan
These attributes make it one of the best Amita 3 propeller options for durability and consistent performance in marine applications.
How to Install Amita 3 – Tohatsu/Nissan Propeller
Installing the Amita 3 propeller is straightforward and can be done with basic tools. Begin by removing the old propeller from the shaft, cleaning the spline, and greasing the hub area. Then slide the new 1512-143-21 propeller onto the shaft, ensuring proper alignment with the thrust washer, spacer, and nut. Use a torque wrench to tighten according to manufacturer specifications.
Pro Tip: Always double-check the propeller nut after your first water run to ensure it remains secure. Proper installation enhances performance and safety, reducing the risk of damage to the lower unit.
Maintenance Tips
Maintaining your Amita 3 propeller is essential to extend its life and optimize your boat’s performance. Follow these maintenance tips:
- Inspect after every trip: Look for dings, cracks, or fishing line wrapped around the shaft.
- Clean regularly: Use mild soap and water to wash off salt, algae, and debris.
- Lubricate shaft: Apply marine-grade grease on the propeller shaft to avoid corrosion and seizure.
- Check torque: Ensure the propeller nut is tight and properly torqued after installation and routine use.
By following these steps, your Amita 3 propeller will stay in peak condition and support smoother, safer voyages.
Performance and Durability Insights
The Amita 3 – Tohatsu/Nissan (14.3 x 21″) LH propeller is manufactured with precision squeeze casting for increased density and strength. Unlike standard die-cast propellers, the squeeze-cast process provides enhanced durability and a smoother hydrodynamic finish. This process improves fuel efficiency and reduces cavitation.
Additionally, the durable powder-coated finish helps the propeller resist corrosion in harsh saltwater conditions. The robust blade geometry ensures excellent thrust even at lower RPMs, making it suitable for fishing, cruising, and towing applications.
Troubleshooting Common Propeller Issues
Even the best propellers may face occasional challenges. Here’s how to handle common problems with the Amita 3:
- Vibration: May be due to bent blades or a damaged hub. Replace or repair as needed.
- Cavitation: Usually caused by damage or improper installation. Inspect and reposition propeller or trim tabs.
- Loss of speed: Often due to worn-out blades or wrong pitch. Consider switching to the correct size like 14.3 x 21″.
Regular maintenance and correct installation significantly reduce these problems, ensuring better marine propulsion performance.

Detailed FAQ Section
Is the Amita 3 – Tohatsu/Nissan (14.3 x 21″) LH propeller compatible with other engines?
This model is designed specifically for Tohatsu and Nissan outboard engines. However, it may be compatible with select Mercury or Mariner engines depending on the spline count and size. Always check OEM specifications or consult a professional before cross-compatibility installation.
How do I know if I need a left-hand rotating propeller?
Left-hand (LH) propellers are generally used in twin-engine boats to counterbalance torque from the right-hand (RH) engine. This setup improves steering and stability. If you’re unsure, check your existing propeller’s rotation or consult your engine manufacturer’s manual.
What are the best maintenance practices for this propeller?
Regular inspection, cleaning, and lubrication are the best practices. After each outing, inspect for visible damage and clean with fresh water. Every few trips, remove the prop to inspect the shaft and reapply marine grease. Avoid running aground or in debris-heavy areas to preserve the blade edge.
Can I install the Amita 3 1512-143-21 propeller by myself?
Yes, DIY installation is possible with basic tools and some mechanical knowledge. You’ll need a wrench set, marine grease, and a cotter pin (if applicable). Follow the engine manufacturer’s instructions closely and verify proper torque once installed.
What is the typical lifespan of this propeller?
With proper use and maintenance, the Amita 3 aluminum propeller can last 3–5 years or longer. Lifespan depends on operating conditions (saltwater vs. freshwater), frequency of use, and handling care. Many users report extended performance when following regular maintenance routines.
