6F50 2011-2012 Ford Edge, Explorer 3.5L AWD/4WD – Remanufactured 6-Speed Automatic Trans

Description

Formulated for deep-water harbor launches, Ford 6F50 Explorer Marine Transmission remanufactured units equip 2011-2012 Ford Edge and Explorer 3.5L all-wheel marine applications. This 6-speed automatic drivetrain directs 315 horsepower at a 6500 RPM input ceiling. Microprocessor-directed valves control ratio changes with a 4.48:1 first gear reduction ratio for responsive maneuvering in crowded ports.

Spheroidal graphite iron casting structures protect internal gears against torsional distortion during heavy open-water cruising. Carburized AGMA Class 11 helical teeth maintain continuous contact to suppress driveline vibration under load. Sintered bronze clutch plates with radial oil channels evacuate friction heat from internal packs. A cupronickel tube bundle heat exchanger with sacrificial zinc anode plumbs to 1.25-inch raw water hoses. Hydraulic connections feature 7/16-20 JIC flare ports. Dry weight spans 230 lbs with 10.5 quarts capacity in an SAE #3 bell housing.

Key Features of Ford 6F50

Shipyards often choose to buy Ford 6F50 marine transmission packages to refit municipal patrol launches and pilot boats. This remanufactured multi-speed drivetrain integrates advanced electronic controls to deliver smooth acceleration and lower fuel consumption.

• 285 PSI control circuit pressures prevent clutch slippage under high-demand engine torque curves
• 6 forward gear ratios step down from 4.48:1 to 0.74:1 to match engine torque to propeller pitch
• 2.6 gallon per minute internal pumps drive oil through heat exchanger tubes to prevent overheating
• 12-volt pulse-width solenoids execute gear shifts within 80 milliseconds for clean acceleration without hesitation
• 4.48:1 reduction planetary gears deliver high low-end torque for rapid harbor maneuvering
• 275 lb-ft torsional damper plates absorb engine vibration ahead of this 6F50 marine transmission package
• 6 bolt companion flanges transfer shaft rotation straight to inboard shaft couplings

Clutch Pressure Torque Dynamics

Operating clutch line pressures stay between 215 and 285 PSI pump pressure to maintain clutch lockup without slippage. Sump fluid heat remains bounded between 150°F to 185°F operating sump temperature throughout continuous commercial service. Peak continuous input torque attains 280 lb-ft at 4500 RPM under a medium duty rating. The external heat exchanger achieves a thermal heat rejection rate of 625 BTU/min across raw water circuits. A 4.48:1 first gear mechanical reduction ratio directs deep torque to the wheel to plane heavy watercraft fast.

Thrust Flange Coupler Geometry

The companion flange features a 5.0-inch outer diameter and a 4.25-inch pitch circle diameter drilled for 6 hardened bolts. Internal heavy-duty roller bearings absorb up to 2,250 pounds of continuous propeller thrust force. Flange vertical drop geometry measures 180 mm center distance. Dial indicator alignment runout to the stern tube shaft must remain below 0.003 inches.

Transmission Fluid Maintenance Intervals

Solid-state electronic solenoids govern gear ratios without mechanical push-pull cables, while an upper dipstick port permits quick fluid checks in tight engine compartments. This transmission is not engineered for deep-sea ocean trawlers or continuous commercial harbor push tugs. Routine maintenance protects internal clutch packs.

• Examine fluid clarity and check oil level at the dipstick each shift prior to engine start
• Drain transmission fluid and inspect the magnetic suction screen every 250 hours of operation
• Renew sacrificial zinc anodes inside the water cooler bundle every 12 months during vessel haulout

Commercial Protection Crate Breakdown

Each unit ships with a 2-Year commercial limited warranty defending all internal components against defects. The heavy wood crate holds one bare marine transmission unit, an input torsional flex plate, a seawater oil cooler bundle with mounting bracket, an output companion flange, an oil dipstick, and a factory workshop manual.
