Material:
Our Gearbox is made of aluminum alloy which offers a good balance of strength, weight, and corrosion resistance.

The gear box 63V-45300 for Yamaha outboard motors is part of the lower unit assembly.
Its primary functions include:
 

1. Power Transmission: It transfers power from the engine to the propeller, allowing the boat to move.

2. Gear Reduction: The gearbox reduces the engine's RPM to a more manageable speed for the propeller, optimizing performance and efficiency.

3. Directional Control: It allows for steering and maneuverability by changing the angle of the propeller in relation to the hull.

4. Support: It houses bearings and supports the propeller shaft, ensuring stability during operation.

What's the differences between long and short gearbox?
 

The long and short gear boxes for Yamaha outboards accommodate different transom heights.

A long shaft is used for deeper transoms, while a short shaft suits shallower ones.

This ensures optimal performance and efficiency in various boat designs and water conditions.
