Solas Amita 3 Stainless Rear Right Propeller 13x19 for Volvo Penta DuoProp

The Solas Amita 3 13x19 stainless rear propeller is part of the C5 set for Volvo Penta Duoprop – meaning it’s intended to run with a 15x19 front prop, together forming a duo with 19″ pitch. This is the most popular configuration for many mid-sized sport and cruiser boats, as 19P offers an excellent compromise between strong acceleration and high top speed.

When installed as the rear prop (right-hand rotation), the 13x19 handles roughly 40% of the total thrust while the front prop (left rotation) handles the remaining ~60%. This balance is optimized to reduce cavitation and increase overall propulsive efficiency. The stainless material allows the blades to be thinner and stiffer, improving hydrodynamics – the boat can achieve higher speeds due to reduced drag of the blades moving through the water.

On-water performance: With a 15x19 + 13x19 set, a typical 22-foot boat with ~250 HP can attain a significantly higher top speed (perhaps +3-5 knots) compared to a 17P set, while still planing easily. At cruising speed, the engine RPM will be lower, often resulting in quieter operation and better fuel economy.

Of course, choosing the correct pitch depends on the engine reaching its recommended WOT (wide-open throttle) range. 19P is well-suited for powerful engines and lighter or moderate-weight boats. If the boat is consistently heavily loaded or the engine is on the lower end of the power range, a 17P might be more appropriate. Recommendation: Verify that your engine can reach its full RPM with this prop; if not, drop down to a lower pitch.

Installation & Compatibility: The Solas 8531-130-19 rear prop fits DP280/290 and later Volvo Penta drives (C5 series, also applicable to some DP-E models). It has a 19-spline inner hub for direct mounting. Always install with the proper Volvo Penta or Solas cone and locking hardware. After mounting the 15x19 front prop, slide on the 13x19 rear prop, align the blades correctly, and tighten to specification. Ensure the locking tab or bolt is secure.

Maximize Your DuoProp Setup: For best results, use the matching Solas front prop (8532-150-19) with this rear prop. This pairing will ensure the load on the engine is balanced as designed. Boaters upgrading from OEM Volvo props often report similar or improved performance with Solas Amita 3 props, along with cost savings. By maintaining your duo-prop system with quality stainless props like these, you’ll enjoy rapid acceleration, high cruising efficiency, and thrilling top-end speed on the water.
