  • Unit must have trim and tilt for replacement to work. If it has two trim hoses going to each cylinder, it has trim and tilt.

  • Unit has a round cavitation plate on lower unit; replacement unit utilizes the newer style shift.
  • Unit may have an o-ring and/or a preloaded pin on lower unit driveshaft. The replacement will be square.
  • Gear ratio must be confirmed. To be safe, it is best to remove the top cover and count the teeth on the upper gears.
