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.
