Gasket & Seal Kit for MG-5065SC & MG-5065A

What this part is
A complete reseal package tailored to MG-5065SC (shallow case) and MG-5065A case geometry. It replaces aged gaskets, O-rings, and lip seals across covers, shafts, and service ports to eliminate weeping and stabilize hydraulic control pressures.

What it includes

• Form-fit case and cover gaskets for inspection and service plates
  
  

• Lip seals and O-rings for input/output shafts and control interfaces
  
  

• Crush washers (where applicable) for drain, fill, and test ports
  
  

• Selector/actuator seals matched to MG-5065SC & MG-5065A interfaces
  
  

What it fixes

• Chronic oil film or misting around covers and perimeters
  
  

• Aeration/foaming from air ingress at tired seals
  
  

• Control pressure instability due to internal leakage paths
  
  

• Oil contamination risks that shorten clutch life and degrade engagement feel
  
  

Signs you likely need this kit

• Recurring top-offs with no obvious drip—suggesting fine seepage
  
  

• Dampness at selector cover, inspection plates, or shaft exits
  
  

• Fresh oil smear returning shortly after wipe-downs or short trials
  
  

Installation highlights

• Prep sealing faces: remove residue without gouging aluminum
  
  

• Lightly oil seal lips; use guide sleeves over splines to prevent nicks
  
  

• Seat and torque all port fittings on clean, burr-free faces; confirm crush-washer conformity
  
  

• Post-run inspection: verify leak-free perimeters and stable control pressure after a warm run
  
  

Related components to consider

• Overhaul Plate Kit if slipping, shudder, or heat indicates clutch wear
  
  

• Oil strainer service (clean/replace) to protect fresh seals and clutches from legacy debris
  
  

Overhaul Plate Kit for MG-5065SC & MG-5065A

What this part is
A complete clutch pack renewal engineered for MG-5065SC and MG-5065A. Replacing the friction and steel stack restores positive take-up, consistent torque transfer, and predictable shifting under load.

What it includes

• Friction plates specified for MG-5065 control pressures and thermal cycles
  
  

• Steel separator plates precision-ground for flatness/parallelism to prevent hot spots
  
  

• Stack-height guidance to achieve correct clutch pack height and plate order
  
  

• Assembly aids (where applicable) to streamline staging, indexing, and pre-lube
  
  

What it fixes

• Slip under throttle in ahead or astern
  
  

• Delayed, harsh, or double-bump engagement from glazed frictions or warped steels
  
  

• Burnt-odor oil and dark debris signaling overheated clutch material
  
  

• Inconsistent maneuvering control during docking and tight-quarters work
  
  

Signs you likely need this kit

• RPM flare without proportional vessel movement when engaging gear
  
  

• Shudder on pickup or a grab–release–grab feel at low throttle
  
  

• Heat rise in the gearbox after frequent low-speed maneuvers
  
  

• Metallic/fibrous residue appearing in the oil strainer soon after service
  
  

Installation highlights

• Measure as-found pack height; document plate count and clearances before teardown
  
  

• Dry-stage the stack to confirm order/quantity; then pre-lube all plates before assembly
  
  

• Inspect steels for warp or bluing; replace any heat-spotted components
  
  

• Torque carrier hardware to spec in a cross pattern; verify runout
  
  

• Commissioning: warm, no-load run-in → progressive load checks → recheck oil and inspect for leaks
  
  

Related components to consider

• Gasket & Seal Kit whenever the case is opened
  
  

• Oil strainer cleaning/replacement to protect the fresh clutch surfaces
  
  

• Approved marine oil per MG-5065SC/MG-5065A recommendations after overhaul
