Solas Amita 3 (Left-Hand) Aluminum Propeller 15.3x21 for Yamaha 150-300 HP

The Solas Amita 3-E Plus 15.3x21 left-hand propeller is designed to work in unison with its right-hand counterpart to deliver perfectly balanced thrust on twin-engine boats. As the left-hand version, it installs on the port engine and spins counter-clockwise, opposing the rotation of the starboard prop. This counter-rotation cancels out unwanted lateral forces and makes controlling high-powered boats much easier and straighter.

In terms of build and materials, this left-hand Solas Amita 3 15.3x21 is identical to the right-hand – cast from high-strength aluminum with the same three-blade geometry optimized for V6 engines. It provides reliable thrust, quick acceleration, and good top-end speed for large vessels. Using a matched set of RH + LH propellers reduces strain on the steering system and improves fuel efficiency, as the boat tracks straight without constant course corrections. For twin-engine boat owners, upgrading to this set of Solas aluminum props is an economical solution that preserves excellent performance while adding comfort to the handling.

• Intended for the port engine in twin Yamaha 150-300 HP setups – essential for balanced, safe handling of 7-9+ m boats (large RIBs, offshore fishing yachts, patrol boats)
• When paired with the RH propeller, ensures the boat doesn’t pull to one side – the captain experiences neutral, light steering even at high speeds
• With its durable aluminum construction and lower cost compared to stainless alternatives, this left-hand prop is a practical maintenance choice (easier and cheaper to replace in case of impacts, while retaining strong operational performance)

By adding the Solas Amita 3 15.3x21 LH to your twin-engine boat alongside the matching RH prop, you’ll experience steadier, straight-line tracking and more responsive steering. The entire propulsion system will run smoother, contributing to a more enjoyable and efficient voyage in all conditions.
