VEVOR Outboard Propeller, Upgrade OEM 15 Spline Tooth Aluminum Outboard Boat Propeller Fit Yamaha Engines 60-130 HP, 4-1/4″ Gearcase, 3-Blade, RH (Right Hand Rotation), OEM Parts No. 6E5-45947-00-EL

VEVOR Aluminum Outboard Propeller Delivers 13-1/2″ Diameter for Maximum Thrust Efficiency

The VEVOR aluminum outboard propeller has a 13-1/2-inch diameter and a 15-inch pitch, delivering steady, high-output thrust across a wide range of conditions. These specifications work together to deliver quick acceleration from a stop and steady power at cruising RPMs, reducing cavitation and drag losses.

This propeller’s precise dimensions mean that you can save fuel no matter what you use it for, whether it’s fishing, cruising along the coast, or just having fun on the water. The 15-degree pitch angle keeps the engine running in its optimal RPM range, reducing fuel consumption and extending service intervals under normal loads.

15-Spline Tooth Interface Ensures OEM-Grade Mechanical Fit on Yamaha 60–130 HP Engines

The 15-spline tooth count on the drive shaft interface of this outboard propeller is in line with Yamaha’s factory engineering standards for outboard engines with 60 to 130 HP. The number of splines directly affects how accurately torque is transferred. If they don’t match, the hub will wear out too quickly, vibrate, and lose power, which this propeller avoids when properly matched.

Yamaha’s driveshaft geometry requires that each spline tooth be precisely machined to keep tight tolerances. This mechanical fidelity allows the propeller to deliver full engine torque without rotational slippage. This means that power from the 60–130 HP engine range reaches the water column with no mechanical energy loss at the shaft coupling point.

4-1/4″ Gearcase Compatibility Confirms Direct OEM Replacement Specification

VEVOR made this aluminum outboard propeller for Yamaha outboard engines with a 4-1/4 inch gearcase, which is the standard lower unit diameter for Yamaha’s mid-range engines with 60 to 130 horsepower. The gearcase size controls the hub depth, the length of the nut engagement, and component clearance during rotation. All of these are important for safe operation.

Installers can reuse the original washer and retaining nut because the gearcase measurement matches the OEM part number 6E5-45947-00-EL. You don’t need to find extra parts, which lowers costs and makes it easier to fit them when replacing them on the water or at the dock.

Aluminum Outboard Propeller Press-In Hub Design Allows Tool-Accessible Installation Within Minutes

The press-in hub design on this outboard propeller mimics Yamaha’s factory assembly method, making it easy to install without any special marine tools. The hub fits snugly into the propeller shaft with a controlled interference fit, which automatically sets the correct axial position during hand-press assembly.

This method of installation takes much less time than aftermarket designs that require machined adapters or custom spacers. The direct-replacement design is helpful for mechanics and boat owners who do their own maintenance. It uses the original Yamaha washer and nut to install the part to factory torque specifications in less than 15 minutes on average.

Corrosion-Resistant Aluminum Alloy Construction Rated for Saltwater and Freshwater Use

The blade and hub of this VEVOR aluminum outboard propeller are made from a marine-grade aluminum alloy that resists corrosion in both saltwater and freshwater. The oxide layer on aluminum provides passive protection, and the alloy composition makes it more resistant to stress-corrosion cracking under cyclic hydrodynamic loading.

The choice of material also keeps the propeller’s total weight low, thereby reducing its rotational inertia. A lower rotating mass means the engine responds more quickly to throttle inputs and places less load on the bearings during acceleration. It extends the life of crankshaft and gearcase bearings when used in high-cycle conditions throughout the propeller’s operational lifespan.

Internal Rubber Hub Absorbs Shock Loads to Protect Yamaha Engine Drivetrain Components

There is an internal rubber hub in the core of the outboard propeller. This hub acts as a mechanical buffer between the spline interface and the blade assembly. This rubber part compresses elastically during sudden throttle changes or sudden load changes, absorbing the strongest shock forces before they can reach the engine’s gearcase or driveshaft.

Reduced shock transmission lowers vibration amplitude at the engine mounting points, protecting seals, bearings, and the surfaces where the gears mesh. A quieter operation is a secondary benefit. Damping vibration reduces noise that travels through the hull, making the experience on the water more pleasant during long trips or low-speed trolling.

3-Blade Right-Hand Rotation Profile Optimized for Yamaha Mid-Range Engine Torque Curves

This aluminum outboard propeller has three blades that spin to the right and are designed to fit Yamaha 60–130 HP four-stroke outboard engines. Three evenly spaced blades keep the hydrodynamic loading balanced during each rotation cycle. It reduces propeller vibration while maintaining sufficient blade area for efficient thrust generation at mid-range RPMs.

Right-hand rotation is the same as Yamaha’s standard single-engine installation, meaning the propeller will push the boat forward in the right direction without changing the gearbox. Three-blade designs are easier to check for edge damage and balance after grounding contact than four- or five-blade high-performance designs. This is because three blades are easier to inspect.
