Aluminum Propeller 11.1x13R for 25-60HP (High-Speed 3-Blade Prop)

With the 11.1x13 aluminum propeller, your 25-60 HP outboard can reach its full speed potential. This prop has a slightly smaller diameter (11.1″) and a higher pitch (13″), making it ideal for boats that are not heavily burdened – for example, moderately light runabouts or RIBs running with 1-2 people and minimal gear. In practice, the higher pitch means the boat travels further with each revolution of the prop, resulting in a higher top speed under the right conditions. If your 40-60 HP engine hits the rev limiter easily with a standard prop (lower pitch), switching to a 13″ pitch can bring the WOT (wide-open throttle) RPM down and increase speed without sacrificing efficiency.

This propeller is engineered with quality in mind – it’s cast from a tough aluminum alloy that withstands minor debris impacts and long-term use. It’s finished with a special anti-corrosion coating so it can be used in saltwater conditions without issue. Its 13-spline hub fits perfectly on the shafts of Yamaha, Honda, Parsun, and Selva engines from 30 to 60 HP, ensuring an easy swap. After installing this prop, you’ll notice reduced engine noise and smooth boat movement at cruising speeds, as the engine can run at lower RPM to maintain the same velocity.

• Ideal Applications: Boats of medium size (~4 – 5.5 m) with relatively light loads where speed is a priority. Example: a 50 HP motor on a light aluminum boat or RIB that’s mainly used for quick trips or leisure cruising – this prop will allow a higher top end compared to a lower-pitch prop.
• Recommended For: Skippers who typically operate their boat with partial load and want to improve fuel efficiency and speed during cruise. A 13″ pitch will reduce unnecessary engine RPM when traveling at a sustained high speed, translating to quieter operation and lower fuel consumption.
• Note: If your boat is heavier or frequently used for towing water toys/skiers, an 11″ or 12″ pitch prop might be more suitable for strong pulling power. But for normal conditions with a light load, the 11.1x13 prop will unleash your engine’s potential for faster and smoother travel.
• Compatibility: Compatible with 13-spline drive shafts on Yamaha, Honda, Selva, Parsun engines in the 25-60 HP class. This covers common 2-stroke and 4-stroke models – e.g., Yamaha 40V/50H, Honda BF50, etc. It installs easily as a direct replacement of the OEM propeller and retains the manufacturer’s standard handling characteristics.
