The gear box 6B4-45300 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. |
