Key Features of the Amita 3 Yamaha 14.5×19
- OEM-quality aluminum construction for marine durability

Why Choose a Left-Hand (LH) Marine Propeller?
A common question for marine enthusiasts is whether to use an LH or RH propeller. The Amita 3 Yamaha 14.5×19 LH Propeller is specifically designed for boats with twin-engine setups where a counter-rotating propeller is required. This arrangement helps balance torque and enhances straight-line tracking, improving navigation especially during docking and low-speed maneuvers.
In some hull designs and conditions, LH props also provide enhanced grip in the water and slightly better reverse performance. It’s essential to match the propeller rotation to your engine and transom specifications.
Performance Benefits of the Amita 3 Yamaha Marine Propeller
The Amita 3 Yamaha marine propeller is designed to deliver smooth acceleration, optimal fuel economy, and responsive steering. Its blade design and rake angle are tuned to reduce ventilation and cavitation under load, ensuring a steady ride even during sharp turns and choppy conditions.
This propeller is ideal for boaters seeking the best of both worlds — dependable cruising and sporty top-end performance. Whether you own a fishing rig or a recreational boat, this propeller offers noticeable enhancements over standard options.
Maintenance Tips
Proper maintenance of your Amita 3 Yamaha 14.5 x 19 LH propeller ensures longevity and sustained performance. Here are some practical tips:
- Inspect regularly: Check for nicks, dings, or cracks after each trip.
- Clean after use: Rinse with fresh water to remove salt, sand, or algae.
- Grease the prop shaft: Prevents corrosion and seizing.
