Overview / What Is the Amita 3 Propeller

The Amita 3 (14.3 × 21″) LH Solas propeller is a three‑blade aluminum design with 14.3‑inch diameter and 21‑inch pitch engineered for left‑hand rotation. Built with Solas’ “exclusive squeeze cast process,” it’s stronger than standard aluminum props and finely balanced to reduce vibration and improve thrust efficiency :contentReference[oaicite:0]{index=0}.

Designed for Evinrude, Johnson and OMC sterndrive engines ranging between 90 and 300 HP, this propeller fits lower units with a 15‑tooth spline and rubber hub system that cushions impact and minimizes driveline shock :contentReference[oaicite:1]{index=1}.

Design and Performance Features

Solas’ squeeze cast aluminum process yields prop blades that resist bending and fatigue better than typical cast aluminum alternatives. This ensures longevity and smoother operation over time :contentReference[oaicite:2]{index=2}.

The rubber hub acts as a fail‑safe—protecting gearcases and smoothing shifting by absorbing abrupt loads. The LH rotation makes this propeller perfect for counter‑rotating dual‑engine setups or specific motor configurations where torque balance is essential :contentReference[oaicite:3]{index=3}.

Compatibility and Fitment Guide

The Amita 3 propeller marine model 2512‑143‑21 fits many Evinrude/Johnson/OMC outboards: models from 90 HP V4 (1995 & newer) to 300 HP V8 (2009 & newer), including E-TEC variants and sterndrives like Cobra and King Cobra series :contentReference[oaicite:4]{index=4}.

Also compatible with OMC/Volvo Penta lower units with standard OEM hub and 15‑tooth spline. Check exact engine year, shaft length, and exhaust fitment before ordering :contentReference[oaicite:5]{index=5}.

Maintenance Tips

Regular care ensures the Amita 3 remains effective season after season. After each outing, rinse the propeller with fresh water and inspect for dents or gouges. Saltwater users should pay extra attention to rinse thoroughly and dry before storage.

Apply marine‑grade grease on the shaft periodically to mitigate corrosion and avoid seizure. Torque the prop nut to manufacturer specifications and replace cotter pins when needed to secure it properly.

How to Install the Amita 3 Propeller

Installing the Amita 3 propeller is straightforward. Remove the old prop by extracting the cotter pin and nut, then slide it off the shaft. Clean and grease the shaft before positioning the new propeller with proper thrust washer.

Torque the nut to spec, insert a new cotter pin, and ensure the propeller spins freely without wobble. Confirm correct rotation direction (LH vs RH) to avoid performance issues or damage.

Best Usage Scenarios and Troubleshooting

This LH propeller performs exceptionally well in dual-engine boats where counter-rotation reduces torque steer and improves handling. For single-engine boats that require LH rotation, it provides excellent mid-range punch and fuel economy.

If you notice excessive vibration, cavitation, or reduced responsiveness, inspect the blades for damage or imbalance. Wrong pitch, damaged hub, or incorrect hub spacing may cause these symptoms. The Amita 3 is engineered to resist such issues through balanced design and robust hub construction.

Expert Advice and Pro Recommendations

Marine propulsion experts highlight the Amita 3 – 2512‑143‑21 as a reliable and affordable performance upgrade over OEM or generic aluminum props. Its balance between cost, durability, and performance makes it a favorite for fishing, cruising, and watersports.

It’s especially recommended for marine environments requiring balanced left‑hand rotation. Buy now with code WELCOME5 for 5% off: Amita 3 – Evinrude/Johnson/OMC (14.3 × 21″) Solas LH Propeller, 2512‑143‑21.

Detailed FAQ Section

Is the Amita 3 14.3 × 21″ LH propeller compatible with all Evinrude/Johnson/OMC engines?

The Amita 3 2512‑143‑21 prop fits a broad range of Evinrude, Johnson, and OMC outboards rated 90 HP to 300 HP, with 15‑tooth spline and 4¼″ gearcase. It includes models from V4 and V6 (DPX, DSX, E‑TEC) and V8 engines up to 300 HP. However, compatibility depends on shaft length, hub type and exhaust configuration. Always consult your engine manual or Solas fitment guide to confirm fit before installation to prevent improper fitment and ensure optimal use.

How to install Amita 3 propeller Marine correctly?

Installing the Amita 3 propeller marine variant requires a set of basic tools: marine grease, torque wrench, nut and cotter pin. First remove old prop, clean and grease shaft. Fit thrust washer, slide on propeller, torque nut, insert new cotter pin. Confirm prop spins freely, secure rotation and alignment. Test at idle before full throttle. Correct installation ensures performance, avoids shaft damage, and secures safety at high RPMs. Improper installation may result in wobble, vibration or reduced top speed.

What are the cost and durability benefits of this propeller?

The Amita 3 14.3 × 21 LH propeller balances cost and durability. Made through squeeze cast aluminum, it offers stronger blades than traditional cast versions but at a fraction of stainless steel cost. It provides excellent resistance to corrosion and fatigue under normal marine conditions. With proper maintenance, lifespan can exceed several seasons. Its rubber hub adds protection, reducing risk of gearbox damage during impacts. In summary, performance and long-term value make it a durable, cost‑effective choice compared to OEM or stainless alternatives.

What maintenance tips prolong Amita 3 propeller lifespan?

Regular inspections and care are key. After each trip, rinse thoroughly with freshwater, then inspect blades and hub for damage. Remove marine growth and salt deposits. Apply marine grease to the shaft periodically to avoid corrosion and seizing. Torque the prop nut per engine spec and always replace cotter pins. Store propeller in dry conditions when not in use to prevent degradation. If bent or nicked, repair promptly to restore balance. These steps ensure the prop—especially the Amita 3 propeller marine version—delivers optimal results season after season.

How does left-hand (LH) rotation benefit dual-engine setups?

Left-hand rotation propellers like the Amita 3 help balance torque and steering forces when paired with a right-hand prop on twin-engine boats. This counter-rotation improves boat handling, reduces prop walk, and increases overall directional stability. It is essential to match LH and RH propellers when retrofitting engines or replacing props. Choosing mismatched rotation may result in poor tracking, uneven wear, or inefficient fuel use. When properly matched, the Amita 3 LH propeller marine edition delivers smooth, efficient performance in dual-engine configurations.

Conclusion

The Amita 3 – Evinrude/Johnson/OMC (14.3 × 21″) Solas LH Propeller, 2512‑143‑21 stands out as a high‑value, high‑performance choice for boaters seeking reliability, durability and efficient propulsion. Its robust squeeze‑cast aluminum design, rubber hub cushioning, and precision balancing make it a dependable upgrade from OEM or economy propellers.

Whether outfitting a fishing boat, cruiser or performance vessel, this Amita 3 propeller marine variant offers excellent acceleration, smooth handling, and long-term usage—especially for left‑hand rotation setups. With proper maintenance, it’s an investment you’ll enjoy for years.
