Aluminum Propeller 7.5x7R for 2.5-3.5HP Outboard Engine (3-Blade RH)

This 7.5x7 aluminum propeller is specifically designed for the smallest outboard engines (2.5 – 3.5 HP) typically found on lightweight inflatables, tender dinghies, or auxiliary sailboat motors. With a 7.5″ diameter and 7″ pitch, it allows a tiny motor to spin up into its optimal RPM range, providing reliable thrust and steering even at low speeds. The 3-blade design ensures stable propulsion with minimal vibration, which makes it easier to maneuver a small boat in tight spaces and shallow waters.

Built from sturdy aluminum with a corrosion-resistant finish, this propeller is suitable for use in both freshwater lakes/rivers and saltwater environments. Its small size and light weight also make it an excellent spare to carry – it can be stored on board as a backup without taking up much space. Installation is a breeze, mounting in minutes on the standard 9-spline drive shaft used by small outboards from Parsun, Selva, Yamaha, etc.

• Ideal Applications: Perfect for very small craft – inflatable dinghies, rowboats with an outboard, or even canoes equipped with a trolling motor – where a 2-3 HP engine provides propulsion. With this 7.5x7 prop, a small motor can move the boat more efficiently when carrying 1-2 people or a light load.
• Recommended For: Owners of portable outboard motors who want optimal performance and control. The prop helps improve handling during trolling speeds and docking, allowing the engine to operate without undue strain.
• Advantage: Compared to a worn or damaged prop, this aluminum replacement restores the original thrust and fuel efficiency of a small engine. It can be swapped in quickly on the water – an important consideration for extended trips. Keeping a spare propeller on hand ensures peace of mind when cruising far from shore with a small boat.
• Compatibility: Engineered to OEM standards, the prop fits perfectly on the shafts of Yamaha, Selva, Parsun 2 – 4 HP engines (commonly 9 spline). This makes it a universal replacement or spare for numerous models in this class, delivering equal or better performance than the factory prop.
