SOLAS Amita 3 Aluminum 3-Blade Propeller 13x11 for Johnson/Evinrude 40-50 HP

The SOLAS Amita 3 13x11 is a specialized low-pitch prop designed to give maximum torque and thrust for boats that need more “oomph” when starting off or operating under load. With a 13-inch diameter and 11-inch pitch, this propeller essentially acts like a “low gear” for your Johnson/Evinrude 40-50 HP outboard. If your boat has been struggling to plane or your engine has been laboring with a higher-pitch prop, switching to an 11″ pitch can dramatically improve the situation.

The larger diameter of the prop (combined with the wide blades of the Amita 3-C series) means that each rotation moves a big volume of water. This provides a strong forward push, allowing heavy or sluggish boats to get going with authority. For instance, pontoon boats, cargo/work boats, or heavy fishing vessels with 40-60 HP engines will see a significant improvement in load-carrying ability and steering control at low speeds. Additionally, during trolling (slow fishing speeds), this prop enables movement at low speeds without putting undue strain on the engine.

The construction of the SOLAS Amita 3 13x11 is the same high-quality aluminum alloy, pressure cast for strength, that Solas uses in all its props. This ensures resistance to impact from floating debris and deformation. The finish, in turn, prevents corrosion, so even with frequent use in saltwater, the prop will remain functional and reliable. If you’re looking for a prop that will give you the “muscle” for takeoff and work, this model is the right choice.

Use Cases & Recommendations:

• Recommended for heavily-loaded boats (4–6+ m) – ideal for pontoon boats, utility/work boats, heavy fishing boats or barges with ~40-60 HP engines, where thrust is prioritized over speed
• Maximum launch thrust: With this prop, your boat will pull away from a standstill much more easily. For example, if you carry cargo or equipment, or pull trawling gear/nets, the low 11″ pitch gives you the power needed to start moving without “overworking” the motor
• Low-speed operation (trolling): For anglers who troll at low RPM – this prop keeps the boat moving at minimal speeds without the engine bogging down or stalling, as it allows the motor to run more freely
• Compatibility: Fits Johnson/Evinrude 40-50 HP (13 spline, 3.25″ gearcase) and equivalent BRP models. Also compatible with Suzuki DT/DF 40-65 HP, including Suzuki DF50/60A 4-strokes (relevant for Johnson 50 4-stroke models). Replaces high-thrust OEM props (e.g., OMC “eleven pitch” props) – check your motor and gearcase specs for precise fit
