SE205 Mercury OB Lower Unit

SE205 (Replaces Most 3 & 4 Cylinder Mercury OB)

Replaces most Mercury 3&4 Cylinder 2-Stroke 1987 and newer 70-125 HP
Also replaces most 75-115 HP 4-Stroke below Serial #OT801000.
This unit will not replace a 3 jaw lower unit unless you also change the shift shaft in the midsection.

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.
