RE537146 is identified by John Deere's official parts catalog as an external-fan alternator rated 28 volts and 50 amps. Deere replacement-parts guides publish it for the 6068SFM75 PowerTech 6.8L marine engine and the 6068TF275 PowerTech 6.8L OEM engine under option code 3142. The same official guides identify RM100225 and SE501341 as remanufactured service units for RE537146. The former 12V 95A description is incorrect and has been removed. Confirm RE537146, 28V/50A output, connector layout, pulley and engine option code before ordering.
Send the machine model, engine model or nameplate photo so our team can confirm compatibility before shipment.
