Aluminum Propeller 11.6x11R for 25-60HP Outboards (High Thrust 3-Blade)

This 11.6x11 aluminum propeller is part of the “G” series designed for mid-range outboard engines (25-60 HP) where extra thrust is needed. With an impressive 11.6″ diameter and 11″ pitch, this prop provides excellent low-end power – ideal for heavier boats loaded with gear or multiple passengers. On 40-50 HP engines mounted on 5-6 meter boats, this pitch helps the vessel plane quickly and maintain a steady speed when towing inflatable tubes or water skiers. The larger diameter improves the prop’s grip on the water, meaning the boat responds instantly to throttle input even under substantial load.

Constructed from high-strength aluminum, this propeller is built for long-term use. The anti-corrosion coating protects it from saltwater and general wear, making it a reliable choice for frequent operation. The prop features a 13-spline hub – the standard for many Yamaha, Honda, Parsun, and Selva engines in the 30-60 HP range. This means installation is straightforward and hassle-free: simply swap out your old prop for the new one using the same spline washer and nut. Once installed, you’ll immediately notice better traction and more powerful acceleration, especially at low RPM.

• Ideal Applications: Medium-sized RIBs, workboats, or family powerboats (around 4.5 – 6 m) that often carry heavy loads or equipment. The 11.6x11 prop helps a 30-60 HP motor develop enough thrust to pull the boat from a standstill onto plane quickly and confidently.
• Recommended for Watersports: If you plan on towing water toys (banana boats, tubes) or water skiers with an engine around 40-50 HP, this lower-pitch prop will provide the needed power at launch to lift skiers or inflatables out of the water. It maintains better control at low and mid speeds – key for safety in watersports.
• Heavy Load / Work Use: For fishing vessels or utility boats that operate under load (lots of gear, nets, fuel), the 11″ pitch prevents the engine from “bogging down.” The motor stays within its recommended RPM range, which reduces strain and improves fuel efficiency while pushing the weight.
• Compatibility: The prop is compatible with 13-spline shafts of Yamaha, Honda, Selva, and Parsun 2-stroke and 4-stroke engines roughly between 25 and 60 HP. This includes popular models like the Yamaha 40/50HP series (Pro 50, 55B, etc.) and Honda BF40/50. Thanks to the standard interface, replacing your original prop with this one is easy and retains all factory handling and safety characteristics.
