The paint color for all lower units is transitioning to black as inventory becomes depleted. Therefore, color may vary depending on product availability at time of order

SEI's drives come standard with a three-yearfault-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.
