New SEI / Mercury 1979-2018 150, 175, 200 HP 2.0/2.4/2.5L Gearcase

This listing is for a New SEI / Mercury V6 1979-2018 2.0/2.4/2.5L Gearcase. These models use a plastic water pump and have a 4 3/4" Bullet Diameter.

These units use anodes (sold separately) located above the cavitation plate. They are not designed to replace Sport Master, Torque Master, CLE, or other high performance gearcases. 25" Transom Models from 1988 and older use a 5" spacer between a standard 20" midsection and the lower unit and therefore used longer mounting studs; these must be reused or sourced from elsewhere.

This unit comes with a three-year fault-free warranty. For further details, please see the complete warranty at https://www.obparts.com/sei-marine-parts-warranty-policy/.

If you have any questions about whether this lower unit will work for your motor or gear ratio, please send us an email with your engine model and serial number to customerservice@marinepartswarehouse.com.
