  • Uses the newer style stubshaft with a clip.
  • If your upper shaft is not the newer style you will need to replace it.
  • Unit does not include a Water Pump.
  • Unit does not include the shift shaft. You will need to install your old one and adjust it.

  • You can paint the unit to match your Outboard.

SEI's drives come standard with a three-year, fault-free warranty. This means that the unit is covered for any failure that requires the drive to be repaired or replaced. Run it without lubrication, crash into a stump, suck up some fishing line, it does not matter, the SEI drive is always covered. SEI believes this warranty is one of the best warranties ever offered for a stern drive or a outboard lower unit. Peace of mind while on the water is important, and SEI goes the extra distance to make sure that our products perform.
