Notes about this kit:
Length (inches) from housing mounting face to end of driveshaft. Must match propeller gearbox within 1/8 inch. (Motor driveshaft length increased 7/16 inch in 1992. DO NOT USE OLDER MODEL R JET DRIVES ON 1992 MOTORS!)
Heavier load capability than R6 series.
Also fits E-Tec H.O. motors.
