Selecting the appropriate gear ratio is critical for achieving optimal power transfer, fuel efficiency, and maneuverability. Diesel Pro Power offers a comprehensive selection of rebuilt MG514B transmissions with gear ratios specifically designed to match a variety of operational requirements. The 2.0:1 ratio is ideal for vessels that require a balanced combination of speed and torque, such as patrol boats, fast ferries, and light commercial vessels. This gear ratio delivers efficient cruising capabilities, allowing vessels to maintain higher speeds without compromising control or stability. It’s an excellent choice for operators who need to navigate open waters quickly while retaining enough torque for maneuvering in ports or busy harbors. This ratio also provides smoother transitions between speeds, making it suitable for vessels with variable load conditions. Rebuilt Transmission for Sale (2.0:1 Ratio, MG514B) The 3.0:1 ratio offers a versatile performance profile, making it a popular choice for commercial fishing boats, mid-sized workboats, and utility vessels. This ratio provides a balanced mix of thrust and cruising speed, allowing vessels to handle diverse operational demands effectively. It’s particularly suitable for operators who navigate varying sea states, from calm to moderately rough waters. The increased torque compared to the 2.0:1 ratio provides better handling during loaded operations, such as when returning to port with a full catch or load. Rebuilt Transmission for Sale (3.0:1 Ratio, MG514B) The 4.0:1 ratio is designed to deliver enhanced torque for heavier vessels like cargo boats, larger fishing vessels, and offshore supply boats. This ratio ensures that vessels can handle substantial loads without sacrificing maneuverability or control. Its high torque output makes it ideal for operations requiring precise handling in tight docking situations or when navigating through strong currents. Additionally, it helps maintain fuel efficiency by enabling vessels to operate at optimal propeller speeds, even when fully loaded. Rebuilt Transmission for Sale (4.0:1 Ratio, MG514B) For applications that demand significant thrust at lower speeds, the 4.5:1 ratio is a perfect choice. Commonly used in trawlers, utility boats, and support vessels, this ratio ensures powerful propulsion and steady control, even under challenging sea conditions. Its high torque output allows vessels to maneuver safely and efficiently, particularly when handling heavy loads or operating in confined waterways. The 4.5:1 ratio is a reliable option for operators who need to prioritize control and pulling power over speed. Rebuilt Transmission for Sale (4.5:1 Ratio, MG514B) The 5.0:1 ratio provides substantial torque for heavy-duty applications, offering exceptional control and maneuverability for larger vessels. This gear ratio is commonly chosen by operators of large workboats, oilfield support vessels, and heavily loaded commercial vessels. It enables precise handling during critical operations, including towing, docking, and tight maneuvering. Its high torque ensures vessels can operate efficiently, even in strong currents or high-load conditions, while maintaining fuel efficiency and reliability. Rebuilt Transmission for Sale (5.0:1 Ratio, MG514B) The 6.0:1 ratio delivers maximum torque and control for the most demanding marine applications, including tugboats, heavy-duty workboats, and offshore supply vessels. It offers exceptional pulling power, ensuring optimal control during towing, emergency maneuvers, or operations in strong tidal currents. This ratio is the go-to option for operators who need torque above all else, providing a reliable and stable platform for handling the heaviest loads in challenging conditions. Rebuilt Transmission for Sale (6.0:1 Ratio, MG514B) Our Diesel Pro aftermarket plate kits include everything required for a complete transmission rebuild, featuring friction plates, steel plates, seals, and rings.

Essential for major rebuilds and preventive maintenance, safeguarding against costly repairs and ensuring long-term reliability. Our high-quality bearings are essential for maintaining smooth operation, reducing vibration, and extending the lifespan of the MG514B transmission. Input shaft bearings manage high levels of torque from the engine, ensuring consistent power transfer to the transmission. Output shaft bearings support the propeller load, maintaining alignment and reducing stress on the drivetrain. Thrust bearings provide axial stability, critical for preventing misalignment and reducing wear on internal components. Precision-engineered materials and tight tolerances deliver exceptional durability and performance, even under high-load conditions. Enhanced noise reduction improves vessel comfort and operational smoothness. The oil pump is a crucial component, ensuring consistent lubrication and cooling under all load conditions. Maintains optimal oil flow and pressure, even during extended periods of high-demand operation. Prevents oil starvation, protecting critical components such as bearings, gears, and seals from damage. Designed for long-lasting performance, reducing the need for frequent maintenance and minimizing the risk of unexpected failures. Vital for preserving overall transmission health and performance, especially in high-capacity commercial vessels. Rubber blocks, also known as torsional isolators or flexible couplings, play a vital role in the MG514B transmission system by absorbing vibrations and compensating for misalignments. Dampens torsional vibrations, significantly reducing stress on internal components and improving operational smoothness. Compensates for slight misalignments caused by hull flexing, engine movement, or shaft deflection, preserving drivetrain integrity. Marine-grade construction resists oil, saltwater, and high temperatures, ensuring long-lasting durability in harsh environments. Contributes to quieter operation, reducing noise levels onboard and enhancing crew comfort. Quick installation and easy replacement, making them ideal for both planned maintenance and urgent repairs.
