Overview / What Is Amita 3 Marine Propeller
The Solas Amita 3 propeller is a top-selling aluminum, three‑blade model renowned for its value and balanced performance on boat engines between 40–140 HP. Specifically, model 2411‑138‑13 offers a 13.75″ diameter with 13″ pitch, optimized for Evinrude/Johnson and OMC with 13‑tooth spline shafts :contentReference[oaicite:0]{index=0}.
Manufactured using Solas’ exclusive squeeze‑casting process, the blades are stronger and more uniform than with traditional die casting. A four‑coat paint finish provides extended corrosion protection, and the rubber hub reduces vibration, softens shifting, and guards the prop shaft :contentReference[oaicite:1]{index=1}.
Why Choose the 13.75×13” Pitch Configuration?
The 13.75 x 13″ pitch size is a common OEM equivalent for mid‑range speeds and power applications. It strikes an excellent balance between torque for acceleration and top‑end efficiency—ideal for pontoons, commercial utility boats, bass boats, and medium cruisers.
Users report noticeable improvements in hole‑shot, planing efficiency, and RPM consistency across various load conditions. In forums, owners praise its “lowest slip ratio, highest top speed, highest running height without venting and best 0‑20 mph time.” A true performance upgrade in aluminum at a competitive price :contentReference[oaicite:2]{index=2}.
Material, Construction & Durability
The Amita 3 marine propeller uses high-grade aluminum alloy compressed under Solas’ squeeze‐casting method to ensure fine grain structure, uniform density, and superior mechanical strength. It is inherently more reliable than die‑cast props.
A four‐layer paint finish has been validated via over 500 hours of salt water spray testing—simulating more than half a year of typical marine exposure. This results in superior anti‑corrosion performance suited for extended saltwater use :contentReference[oaicite:3]{index=3}.
