Looking for a reliable, ready-to-install Twin Disc MG5065? Our rebuilt MG5065 marine gears are spin-tested for performance and sold on an exchange basis with a refundable core deposit. Choose the reduction ratio that matches your propeller and duty profile, and pair the gear with correct mounts, couplings, and controls from one source. Whether you’re repowering a workboat or restoring a classic yacht, we streamline the process with knowledgeable support and fast shipping to over 180 countries.

Rebuilt MG5065 Gear Options

• Purpose-Built Ratios: Common MG5065 reductions support a range of vessels—from planing hulls that prefer lower ratios to displacement craft that benefit from higher torque at the propeller. If you’re switching ratios, confirm prop diameter, pitch, and shaft load to maintain engine within rated RPM.
  
  

• Spin-Tested Assurance: Every MG5065 in this section is spin-tested for smooth clutch engagement, correct oil pressure, and clean gear mesh before it leaves the shop.
  
  

• Exchange Program: Return your serviceable core to unlock the refundable deposit and keep total project costs predictable.
  
  

Related Mounting & Coupling Components

• Rubber Block for Twin Disc Marine Gears: Durable rubber blocks help isolate vibration between the gear and stringers. Suitable for select MG50X installations (including many MG5065 setups). Always verify dimensions and load rating before purchase.
  
  

• Input Couplings & Drive Adapters: Match coupling spline, bolt circle, and pilot to your engine flywheel housing to prevent misalignment and premature wear.
  
  

• Mounting Hardware & Alignment Shims: Keep the gear aligned within spec to protect bearings, output seals, and shafting.
  
  

Mechanical & Electric Gauges

• Mechanical Gauges (Standard): Straightforward, field-proven monitoring for oil pressure and temperature.
  
  

• Mechanical Gauges with Alarm: Add audible/visual alerts to protect the transmission during long runs or heavy maneuvering.
  
  

• Electrical Gauges, 12-Volt & 24-Volt: Clean dash integration for modern panels; choose the voltage that matches your vessel’s system.
  
  

Controls, Cables & More

• Control Heads & Levers: Single- and dual-station options for precise gear engagement.
  
  

• Premium Cables & Linkage Kits: Reduced friction and tighter tolerances for consistent detent feel at the transmission.
  
  

• Neutral Safety & Detent Accessories: Ensure proper shift logic and safeguard the drivetrain during starts.
  
  

Cooling & Pumps

• Marine Water Pumps: Raw-water pumps sized for marine transmissions help maintain stable oil temperatures under load.
  
  

• Engine Water Pumps: Keep the prime mover running at its designed temperature window—pairing engine and gear cooling improves overall reliability.
  
  

• Brand Coverage: Detroit Diesel, Cummins, Caterpillar, John Deere, and more—consolidate your order to minimize downtime.
