Detailed FAQ Section
What boats are compatible with the Amita 3 – Yamaha (14.3 x 21″) Solas LH Propeller?
The Amita 3 Yamaha 14.3 x 21” propeller fits most Yamaha outboard engines between 115HP and 150HP. It’s ideal for aluminum boats, bass boats, and other mid-sized recreational vessels. The propeller offers a direct fit for standard Yamaha spline configurations and can be used in both freshwater and saltwater applications.

Is aluminum a durable material for marine propellers?
Yes, aluminum propellers like the Amita 3 are squeeze-cast for added strength. They are lightweight, corrosion-resistant, and ideal for recreational boating.

What is the typical lifespan of the Amita 3 propeller?
With proper maintenance, the Amita 3 propeller can last several years. Factors such as water conditions, frequency of use, and storage impact longevity.
