Engine Outboard Propeller: Direct Fit for Mercury and Mariner 90-400 HP Engines with 4-3/4" Gearcase

Fitting certain Mercury and Mariner outboard engines with 90 to 400 HP is very easy with the VEVOR engine outboard blade. When installed on an engine with a 4-3/4-inch gearcase and right-hand rotation, it works the same as the original and requires no changes.

The propeller is the same as OEM No. 48-832832A45, making it easy for boat users to find a replacement. You don't have to pay store prices for this propeller; it fits just as well as the factory original.

15 Spline Tooth Configuration for Precise and Secure Drive Shaft Engagement

The engine outboard propeller has 15 spline teeth that fit securely and correctly onto the Mercury and Mariner engine driveshaft. The number of splines is the same as the original engine, so the link stays tight and doesn't move at high speeds.

A strong spline link keeps the engine's full power going to the water. When spline numbers are too low or too high, they cause vibration, early wear, and lower performance over time. Because it has 15 splines, it doesn't have these problems and always sends power.

14-1/4 Inch Diameter and 21 Inch Pitch for Powerful High-Speed Cruising

The VEVOR engine outboard propeller has a 14-1/4-inch diameter and a 21-inch pitch, providing strong forward thrust. Moving a lot of water with each rotation is possible because the diameter is big. This gives fast boats, larger vessels, and fully loaded watercraft the thrust they need to go fast.

This width and pitch combination works well in high-horsepower applications where both performance and fuel economy are important. Ensuring the pitch is right keeps the process within the best RPM range. This engine boat propeller helps you go faster and use less gas when you're out on the open water.

Engine Outboard Propeller with Corrosion-Resistant Aluminum Alloy Build for Durability

We made the engine outboard propeller from an aluminum alloy that doesn't rust and performs well in both freshwater and saltwater. One of the most corrosive environments for naval parts is saltwater, but this propeller can withstand it and doesn't degrade over time.

The aluminum also keeps the propeller light, directly improving the engine's rotational efficiency and reducing the load it has to carry during operation. There are lighter propellers on the market that reach operating speed faster, respond more quickly to throttle changes, and maintain momentum better than heavier cast-iron or stainless-steel propellers.

3-Blade Right-Hand Rotation Design for Balanced Thrust and Smooth Propulsion

The VEVOR engine outboard propeller has three blades that rotate clockwise. This makes it efficient and balanced at a wide range of speeds. For high-horsepower outboard applications, three-blade propellers offer the best balance of thrust, smoothness, and fuel economy.

Right-hand rotation is the same as the standard rotation of Mercury and Mariner outboard engines. This ensures that the thrust is directed correctly and that the steering responds correctly at all throttle levels. Putting in a propeller that turns in the right direction is very important for keeping the boat safe and stable at all speeds and in all types of water.

M21 Interchangeable Hub Kit Included for Fast and Secure Propeller Mounting

The engine-outboard propeller comes with a strong M21 interchangeable hub kit, making the fitting process much easier. The hub kit provides a safe, solid connection between the propeller and the engine's drive shaft. It doesn't need any special tools or professional installation.

The M21 hub kit's replaceable design makes it very easy to change or improve propellers in the future without having to buy a new hub every time. This saves you a lot of money on replacements in the future and makes switching motors between trips easy and quick. In the long run, this means you get more value from a single hub investment.

Internal Rubber Hub Absorbs Shock Loads and Reduces Engine Vibration and Noise

The outboard blade for the VEVOR engine has a rubber hub inside that protects the engine from sudden shock loads while it's running. The rubber hub absorbs the full impact force before it reaches the engine, protecting critical internal parts from costly damage.

The rubber hub stops vibrations while it's working, making the ride smoother and quieter at all speeds. Less shaking makes the ride more comfortable for everyone and, in the long term, helps keep the engine mounts from wearing out. The outboard blade on your engine helps protect it by absorbing shocks.

Strictly Pre-Shipment Tested for Proper Balance, Fitment, and Reliable Performance

Before it leaves the factory, every VEVOR outboard engine propeller undergoes strict quality checks to ensure it fits properly and works well. Carefully measuring each unit's size, balancing the blades, and checking the hub's integrity ensures it meets all Mercury and Mariner engine requirements for safe marine use.

Testing before shipping ensures the propeller fits properly and works reliably from the very first use. You don't have to worry about losing balance or unexpected vibrations. The VEVOR engine outboard propeller is a reliable option for marine use because it undergoes strict quality control.
