Overview of Twin Disc MG-506 2.96:1
The Twin Disc MG-506 marine transmission with a 2.96:1 gear ratio is designed to handle significant power outputs while providing a high reduction for better thrust and control at lower RPMs. This ratio is particularly useful for boats that need to operate efficiently at slower speeds or require extra torque for pushing or towing.
Key Specifications (Approximate, as models can vary):
-
Gear Ratio: 2.96:1 (reduces engine RPM to propeller RPM, providing higher torque but lower top speed).
-
Power Rating: Typically supports engines up to 300-400 horsepower, depending on the exact model (e.g., MG-506-1 or MG-506-A) and year of manufacture. Maximum input torque and RPM (usually around 3000 RPM) should be checked in the specific technical manual.
-
Oil Capacity: Around 1.2 to 1.3 U.S. gallons (4.5 to 5 liters), depending on the housing and cooling system. Use straight 30-weight oil or as specified by Twin Disc.
